field of technique
[001] The present invention is related to the field of sprayable aqueous compositions. In particular, the present invention relates to sprayable aqueous compositions which include an anti-mist component to control droplet size. Fundamentals
[002] Sprayable compositions can be applied to a hard surface with a transient trigger spray device or an aerosol spray device. These cleaners have great utility due to the fact that they can be applied by spraying to vertical, suspended or slanted surfaces. Spray devices create a spray pattern of aqueous sprayable compositions that come in contact with target hard surfaces. Most of the sprayable composition is found on the target hard surfaces as large spray deposits, while a small part of the sprayable composition can become a mist or aerosol suspended in the air, which consists of small particles that comprise the cleaning composition that can remain. suspended or dispersed in the atmosphere surrounding the dispersal site for a period of time, such as between about 5 seconds to about 10 minutes.
[003] Aqueous sprayable compositions can be supplied as concentrated solutions that can be diluted with water to form use solutions. Such concentrated solutions reduce transport and storage costs as the dilution water is not transported or stored, but is preferably added to the solution at a later time. In some embodiments, it is preferred that the concentrate be stable at high temperatures and low temperatures, such as those experienced during shipping and storage. summary
[004] In one embodiment, a non-Newtonian concentrate composition includes at least one acid, at least one surfactant, and an anti-mist component. The anti-mist component is selected from polyethylene oxide, polyacrylamide, polyacrylate and combinations thereof. The non-Newtonian composition has a viscosity less than about 40 centipoise.
[005] In another embodiment, the non-Newtonian concentrate composition includes water, at least one surfactant and an anti-mist component. An additional modality is a method of using a concentrated cleaning solution. The concentrated cleaning solution includes a surfactant and an anti-mist component and is diluted with water to form a wearing solution having an anti-mist component concentration of between about 0.002% and about 0.006%, by weight, where the anti-mist component is selected from polyethylene oxide, polyacrylamide, and combinations thereof.
[006] One more additional modality consists of a method of using a concentrated cleaning solution, where the concentrated solution is diluted with water to form a use solution that has a polyacrylate concentration between about 0.2% and 5% , by weight.
[007] Although multiple embodiments are presented, other embodiments of the present invention will become apparent to those skilled in the art from the detailed description, which shows and describes illustrative embodiments of the invention. Consequently, the drawings and detailed description are to be considered as illustrative in nature and not restrictive. Brief description of the drawings

[011] The present invention relates to concentrated spray compositions that include an anti-mist component, such as polyethylene oxide, polyacrylamide or polyacrylate, and solutions for using the same. In one embodiment, the concentrated spray compositions can contain a sufficient amount of anti-mist component such that when the concentrate is diluted with water to form a use solution and is dispensed from a transient trigger spray, the solution of use exhibits an increased average droplet size and reduced mist or aerosol. In one embodiment, the sprayable use solution produces little or no small particle aerosol. In another embodiment, when dispensed with a trigger sprayer, a sprayable use solution has an average droplet size above 50 microns. It has been found that increasing the droplet size of the dispensed use solution can reduce inhalation, aerosol and mist.
[012] Sprayable compositions can be used in any environment where it is desirable to have larger droplet sizes dispensed from a transient trigger spray. For example, the sprayable composition can be used in institutional applications, food and beverage applications, healthcare applications, vehicle care applications, pest elimination applications and laundry applications. Such applications include, but are not limited to, stain removal and cleaning of fabric and laundry, stain removal and kitchen and bathroom cleaning, stain removal and carpet cleaning, stain removal and vehicle cleaning, car cleaning, local operations, general purpose stain removal and cleaning, stain removal and surface cleaning, particularly hard surfaces, glass window cleaning, air renewal or flavoring, industrial or household cleaners, antimicrobial cleaning. Methods of using the sprayable compositions are also provided.
[013] The concentrated spray composition includes at least one anti-mist component, such as polyethylene oxide (PEO), polyacrylamide or polyacrylate. The anti-mist component can work to reduce atomization and mist of the spray solution when dispensed using a sprayer, which includes aerosol sprays and transient trigger sprays. Transient trigger sprayers include stock transient trigger sprayers (ie non-low speed trigger sprayers) and low speed trigger sprayers, both available from Calmar. Commercially available suitable stock transient trigger sprayers include 1.66 HP Calmar Mixor trigger sprayer. The anti-mist component can also increase the average particle size of the dispensed hold solution, which reduces inhalation of the hold solution and particularly reduces inhalation of the sensitizer or irritant.
[014] In one example, the concentrated spray composition includes polyethylene oxide (PEO), polyacrylamide or polyacrylate. In another example, the concentrated spray composition includes blends of polyethylene oxide (PEO), polyacrylamide and polyacrylate. In a further example, the concentrated spray composition includes blends of polyethylene oxide (PEO) and polyacrylamide. PEO is a high molecular weight polymer. A suitable PEO can have a molecular weight between about 3,000,000 and about 7,000,000. A commercially available PEO consists of Polyox WSR 301, which has a molecular weight of about 4,000,000 and is available from Dow. A suitable concentration range for PEO is between approximately 0.01% and 0.3% by weight of the concentrated spray solution. A particularly suitable concentration range for PEO is between approximately 0.01% and 0.2% by weight of the concentrated spray solution.
[015] The anti-mist component may alternatively or additionally include a polyacrylamide. A suitable polyacrylamide can have a molecular weight between about 8 million and about 16 million, and more suitably between about 11 million and about 13 million. A commercially available polyacrylamide is SuperFloc® N-300 available from Kemira Water Solutions, Inc. A suitable concentration range for polyacrylamide is between approximately 0.01% and 0.3% by weight of the concentrated spray solution. A particularly suitable concentration range for polyacrylamide is between approximately 0.01% and 0.2% by weight of the concentrated spray solution.
[016] Polyacrylate is a high molecular weight polymer. A suitable polyacrylate polymer can have a molecular weight between about 500,000 and about 3 million. A more suitable polyacrylate polymer can have a molecular weight of at least about 1 million. A commercially available polyacrylate is Aquatreat® AR-7H available from Akzo Nobel. Suitable polyacrylate concentrations in the concentrate composition are between about 0.5% and about 20% by weight. Particularly suitable polyacrylate concentrations in the concentrate composition are between about 1% and about 10% by weight.
[017] Concentrated spray compositions may optionally include at least one stability component. The effectiveness of an anti-mist component to reduce haze and increase droplet size may degrade over time. A stability component can reduce the degradation of the anti-mist component and improve the shelf life of the concentrated spray composition. Suitable stability components can include antioxidants, chelators and solvents. Example antioxidants include, but are not limited to, Irganox® 5057, a liquid aromatic amine antioxidant, Irganox® 1135, a liquid hindered phenolic antioxidant, Tinogard NOA, and Irgafos 168, all available from BASF. Additional exemplary antioxidants include vitamin E acetate. Exemplary chelators include, but are not limited to: sodium gluconate, sodium glucoheptonate, N-hydroxyethylenediaminetriacetic acid (HEDTA), ethylenediaminetetraacetic acid (EDTA), nitrilotriacetic acid (NTA) , diethylenetriaminepentaacetic acid (DTP A), ethylenediaminetetrapropionic acid, triethylenetetraaminehexaacetic acid (TTHA), and their substituted ammonium salts, ammonium and alkali metal thereof, tetrasodium salt of ethylenediaminetetraacetic acid (EDTA), trisodium salt of nitrilotriacetic acid (NTA), ethanoldiglycine disodium salt (EDG), diethanolglycine sodium salt (DEG) and 1,3-propylenediaminetetraacetic acid (PDTA), dicarboxymethyl glutamic acid tetrasodium salt (GLDA), methylglycine-NN-diacetic acid trisodium salt (MGDA) and salt iminodisuccinate sodium (IDS). Suitable commercially available chelators include Dissolvine® GL-47-S, tetrasodium glutamate diacetate and Dissolvine® GL-38, glutamic acid, N-N-diacetic acid, tetrasodium salt, both available from Akzo Nobel. Exemplary solvents include, but are not limited to, propylene glycol and glycerin. A suitable concentration range of stability components includes between approximately 100 parts per million (ppm) and approximately 100,000 ppm of the concentrated spray composition or between approximately 0.01% and 10%, by weight. A particularly suitable concentration range of stability components includes between approximately 100 parts per million (ppm) and approximately 70,000 ppm of the concentrated spray composition or between approximately 0.01% and 7%, by weight.
[018] Concentrated sprayable compositions can include a combination of stability components, which can additionally improve the stability of the composition. For example, concentrated spray compositions can include a combination of two or more antioxidants, chelators and solvents. In one example, the concentrated spray composition can include an antioxidant and a chelator. In a further example, the concentrated spray composition may include Irganox® 1135 and Dissolvine® GL-47-S. It has been found that, when used in combination, the effective amounts of Irganox® 1135 and Dissolvine® GL-47-S are half the effective amounts of each when used alone.
[019] The concentrated sprayable composition consists of a non-newtonian fluid. Newtonian fluids have a short rest time and have a direct correlation between elongation and shear viscosity (the elongation viscosity of the fluid equals three times the shear viscosity). Shear viscosity is a measure of a fluid's ability to resist the movement of layers relative to one another. Stretch viscosity, which is also known as stretch viscosity, is a measure of a fluid's ability to elastically stretch under stretch stress. Non-Newtonian fluids do not have a direct correlation between elongation and shear viscosity and are capable of storing elastic energy when under stress, providing exponentially more elongation than shear viscosity and producing a thickening effect under stress (i.e. , shear thickening). These properties of non-Newtonian fluids result in the sprayable composition which has a low viscosity when not under shear, but which thickens when under tension from the trigger spray to form larger droplets.
[020] The concentrated sprayable composition has a relatively low shear viscosity when not under stress. Shear viscosity can be measured with a Brookfield LVDV-II viscometer using the R1 spindle at 50 rpm and room temperature. As further described below, in one example, the shear viscosity of the concentrated sprayable composition is comparable to the shear viscosity of water. A suitable shear viscosity for the concentrated sprayable composition is about 40 centipoises or less. A more preferred shear viscosity is about 30 centipoises or less. In one example, the anti-mist components do not increase the shear viscosity of the concentrated sprayable composition when not under stress and the increased shear viscosity is created by other components, such as the surfactant. Compared to the low shear viscosity concentrate sprayable composition of the present application, the addition of xanthan gum to a concentrate produces a Newtonian fluid that is too thick to be used as a concentrate. The concentrated spray composition of the present application forms a thin aqueous mixture of low shear viscosity even at high concentrations of the anti-mist component, such as those required for concentrated solutions.
[021] In another example, a flowable concentrate sprayable composition contains a sufficient amount of anti-mist component such that the average particle size of the dispensed use solution is large enough to reduce haze. A suitable average particle size is about 11 microns or larger. A particularly suitable average particle size is about 50 microns or larger. A more particularly suitable average particle size is about 70 microns or larger, about 100 microns or larger, about 150 microns or larger, or about 200 microns or larger. The suitable average particle size may depend on the composition of the use solution and thus on the concentrated sprayable composition. For example, a suitable average particle size for a strongly acidic or alkaline use solution may be about 100 microns or larger, and more particularly about 150 microns or larger, and more particularly about 200 microns or larger. A suitable average particle size for a moderately acidic or alkaline use solution may be about 11 microns or larger, preferably about 50 microns or larger, and more preferably about 150 microns or larger. A strongly acidic working solution may have a pH of about 3 or below, a strongly alkaline working solution may have a pH of about 11 or greater, and a moderately acidic or alkaline working solution may have a pH of between about 3 and about 11.
[022] In one example, concentrated spray compositions consist of concentrated acidic non-Newtonian spray compositions that generally include at least one acid, at least one surfactant, and at least one anti-mist component, such as polyethylene oxide (PEO) or polyacrylamide (PAA ). A suitable concentration range of the components of the concentrated sprayable composition includes between approximately 0.1% and 30% by weight of surfactant, between approximately 0.1% and 75% by weight of at least one acid, and between approximately 0.01% and 0.3% PEO or PAA. Concentrated spray compositions can be diluted with water to form ready-to-use solutions.
[023] In another example, concentrated spray compositions generally include at least one acid, at least one surfactant and polyacrylate. A suitable concentration range of the components of the concentrated sprayable composition includes between approximately 0.1% and 30% by weight of surfactant, between approximately 7% and 75% by weight of at least one acid, and between approximately 0. 5% and 20% polyacrylate. Concentrated spray compositions can be diluted with water to form ready-to-use solutions.
[024] The acid can be a strong acid that dissociates substantially in an aqueous solution, such as, but not limited to, hydrobromic acid, hydroiodic acid, hydrochloric acid, perchloric acid, sulfinic acid, trichloroacetic acid, trifluoroacetic acid, acid nitric acid, dilute sulfonic acid and methanesulfonic acid. Weak organic or inorganic acids can also be used. Weak acids are acids in which the first step of dissociating a proton from the cation portion of the acid does not essentially proceed to completion when the acid is dissolved in water at ambient temperatures at a concentration within the useful range to form the present composition sprayable. Such inorganic acids are also mentioned as weak electrolytes. Examples of weak organic and inorganic acids include phosphoric acid, sulfamic acid, acetic acid, hydroxyacetic acid, citric acid, benzoic acid, tartaric acid, maleic acid, malic acid, fumaric acid, lactic acid, succinic acid, gluconic acid, acid glucaric, and the like. Mixtures of strong acid with weak acid or mixtures of a weak organic acid and weak inorganic acid with strong acid can also be used.
[025] The acid may be present in sufficient amounts such that the concentrated spray composition has an acidic pH. In one example, the concentrated spray composition has a pH of 4.5 or less. In another example, the concentrated spray composition includes between approximately 7% and 75% by weight acid. In a further example, the concentrated spray composition includes between approximately 10% and approximately 65%, by weight, of acid. In a still further example, the concentrated spray composition includes between approximately 40% and 60% by weight of acid. Highly acidic concentrated spray compositions, particularly those which include between approximately 40% and 60% by weight acid, containing at least one anti-mist component, have demonstrated instability when stored at elevated temperatures for extended periods of time. The stability component can improve the shelf life of concentrated spray compositions.
[026] The acid can also include a fatty acid, such as a fatty acid antimicrobial agent or neutralized salt of a fatty acid. Fatty acids include medium chain fatty acids, which include C6-C16 alkyl carboxylic acids, such as hexanoic acid, butyric acid, octanoic acid, heptanoic acid, nonanoic acid, decanoic acid, undecanoic acid, and dodecanoic acid. More suitable fatty acids include a C8-C12 alkyl carboxylic acid, more suitably C9-C10 alkyl carboxylic acid, such as decanoic acid (capric acid). In one example, the sprayable composition includes at least one fatty acid and has a total acid concentration of between about 7% and 45%, by weight. In a further example, the fatty acid comprises between about 1% and 10%, by weight, with a total acid concentration of between about 7% and 45%, by weight.
[027] The concentrated sprayable composition includes a surfactant. A variety of surfactants can be used, which include anionic, nonionic, cationic and amphoteric surfactants. Exemplary suitable anionic materials are surfactants which contain a large lipophilic moiety and a strong anionic group. Such anionic surfactants typically contain anionic groups selected from the group consisting of sulfonic, sulfuric or phosphoric, phosphonic or carboxylic acid groups which when neutralized will produce sulfonate, sulfate, phosphonate or carboxylate with a cation thereof, preferably being selected to from the group consisting of an alkali metal, ammonium, alkanol amine, such as sodium, ammonium or triethanol amine. Examples of operative anionic sulfonate or sulfate surfactants include sodium alkylbenzene sulfonates, sodium xylene sulfonates, sodium dodecylbenzene sulfonates, linear sodium tridecylbenzene sulfonates, potassium octyldecylbenzene sulfonates, sodium lauryl sulfate, sodium palmityl sulfate, sodium cocoalkyl sulfate, sodium olefin sulfonate.
[028] Nonionic surfactants do not carry distinct charge when dissolved in aqueous media. The hydrophilicity of the nonionic is provided by the bonding of hydrogen with water molecules. Such nonionic surfactants typically comprise molecules that contain large segments of a polyoxyethylene group together with a hydrophobic moiety or a compound that comprises a segment of polyoxypropylene and polyoxyethylene. Polyoxyethylene surfactants are commonly manufactured through base catalyzed ethoxylation of aliphatic alcohols, alkyl phenols and fatty acids. Polyoxyethylene block copolymers typically comprise molecules that have large segments of ethylene oxide coupled with large segments of propylene oxide. These nonionic surfactants are well known for use in this area of the art. Additional exemplary nonionic surfactants include alkyl polyglycosides.
[029] The lipophilic moieties and cationic groups that comprise amino groups or quaternary nitrogen can also provide surfactant properties to the molecules. As the name suggests for cationic surfactants, the hydrophilic portion of nitrogen carries a positive charge when dissolved in an aqueous medium. The soluble surfactant molecule can have its solubility or other surfactant properties optimized with the use of low molecular weight alkyl groups or hydroxy alkyl groups.
[030] The cleaning composition may contain a cationic surfactant component which includes a detergent amount of cationic surfactant or a mixture of cationic surfactants. Cationic surfactant can be used to provide disinfection properties. In one example, cationic surfactants can be used in basic or acidic compositions.
[031] Cationic surfactants that can be used in the cleaning composition include, but are not limited to: amines such as primary, secondary and tertiary monoamines with C18 alkyl or alkenyl chains, ethoxylated alkylamines, ethylenediamine alkoxylates, imidazoles such as a 1-(2-hydroxyethyl)-2-imidazoline, a 2-alkyl-1-(2-hydroxyethyl)-2-imidazoline, and the like; and quaternary ammonium compounds and salts such as, for example, alkylquaternary ammonium chloride surfactants, such as n-alkyl(Ci 2 -Cie )dimethylbenzyl ammonium chloride, n-tetradecyldimethylbenzylammonium chloride monohydrate, a naphthalene substituted quaternary ammonium chloride , such as dimethyl-1-naphthylmethylammonium chloride.
[032] Amphoteric surfactants can also be used. Amphoteric surfactants contain both a basic hydrophilic and an acidic moiety in the structure. These ionic functions can consist of any one of the anionic or cationic groups that have been previously described in the sections relating to anionic or cationic surfactants. Briefly, anionic groups include carboxylate, sulfate, sulfonate, phosphonate, etc., while cationic groups typically comprise compounds having amine nitrogens. Many amphoteric surfactants also contain oxide or hydroxyl groups which enhance their hydrophilic tendency. Preferred amphoteric surfactants of this invention comprise surfactants having a cationic amino group combined with an anionic carboxylate or sulfonate group. Examples of useful amphoteric surfactants include the sulfobetaines, N-coco-3,3-aminopropionic acid and its sodium salt, n-tallow-3-amino-dipropionate disodium salt, 1,1-bis(carboxymethyl)-salt 2-undecyl-2-imidazolinium disodium hydroxide, cocoaminobutyric acid, cocoaminopropionic acid, cocoamidocarboxy glycinate, cocobetaine. Suitable amphoteric surfactants include cocoamidopropylbetaine and cocoaminoethylbetaine.
[033] Amine oxides, such as tertiary amine oxides, can also be used as surfactants. Tertiary amine oxide surfactants typically comprise three alkyl groups attached to an amine oxide (N2O). Commonly, alkyl groups comprise two lower (1-4C) alkyl groups combined with a C6 -24 higher alkyl group, or may comprise two higher alkyl groups combined with a lower alkyl group. Additionally, lower alkyl groups may comprise alkyl groups substituted by hydrophilic moiety, such as hydroxyl, amine groups, carboxylic groups, etc. Suitable amine oxide materials include dimethylcetylamine oxide, dimethyllaurylamine oxide, dimethylmyristylamine oxide, dimethylstearylamine oxide, dimethylcocoamine oxide, dimethyldecylamine oxide and mixtures thereof. The classification of amine oxide materials can depend on the pH of the solution. On the acid side, amine oxide materials protonate and can stimulate cationic surfactant characteristics. At neutral pH, amine oxide materials are nonionic surfactants and, on the alkaline side, exhibit anionic characteristics.
[034] Concentrated acid spray compositions include water. Suitable water concentrations include between about 25% and 90% by weight. The most suitable water concentrations include between about 45% and about 70%, by weight, and between about 25% and about 45%, by weight.
[035] In another embodiment, the concentrated sprayable composition consists of a concentrated quaternary sprayable composition that generally includes water, a quaternary compound, at least one of PEO, PAA and polyacrylate, and optionally, may include a stability component. The pH of the concentrated quaternary spray composition can be between about 4 and about 12. Suitable quaternary compounds include quaternary ammonium compounds. When the concentrated quaternary spray composition includes PEO or PAA, suitable concentrations include between about 75% and 95%, by weight, of water, between about 5% and 30%, by weight, of quaternary compounds, less than about 1% of at least one fragrance or dye, between about 0.01 and 0.3%, by weight, of at least one of PEO or PAA, and optionally between about 0.01% and 10%, by weight, of a stability component. In another example, the concentrated quaternary spray composition includes from about 10% to about 20%, by weight, of quaternary compounds. In a further example, the concentrated quaternary spray composition consists essentially of between about 75% and 95% by weight of water, between about 5% and 30% by weight of quaternary compounds, less than about 1 % of at least one fragrance or dye, between about 0.01% and 0.3% by weight of at least one of PEO or PAA, and optionally between about 0.01% and 10% by weight , of a stability component.
[036] When the concentrated quaternary sprayable composition includes polyacrylate, suitable concentrations include between about 75% and 95% by weight of water, between about 5% and 30% by weight of quaternary compounds, less than about 1% of at least one fragrance or colorant, between about 0.5% and 20% by weight of polyacrylate and optionally between about 0.01% and 10% by weight of a stability component . In a further example, the concentrated quaternary spray composition consists essentially of between about 75% and 95% by weight of water, between about 5% and 30% by weight of quaternary compounds, less than about 1 % of at least one fragrance or colorant, between about 0.5% and 20% by weight of polyacrylate and optionally between about 0.01% and 10% by weight of a stability component.
[037] In a further embodiment, the concentrated sprayable composition consists of a concentrated sprayable ambient flavor composition. In one example, the concentrated sprayable ambient flavor composition includes water, at least one nonionic surfactant, at least one anionic surfactant, at least one of PEO, PAA and polyacrylate, at least one fragrance or colorant, and optionally may include a stability component and/or a microbiocide. Suitable concentrations, when the anti-mist component consists of PEO or PAA, include between about 50% and 90% by weight of water, between about 1% and 15% by weight of nonionic surfactant, between about 1% and 10%, by weight, of anionic surfactant, between about 0.01% and 0.3%, by weight, of at least one of PEO and PAA, between about 0.05% and 15%, in weight, of at least one fragrance or colorant, and optionally can include between about 0.01% and 10%, by weight, of at least one stability component. Suitable concentrations, when the anti-mist component consists of polyacrylate, include between about 50% and 90% by weight of water, between about 1% and 15% by weight of nonionic surfactant, between about 1% and 10% by weight of anionic surfactant, between about 0.5% and about 20% by weight of polyacrylate, between about 0.05% and 15% by weight of at least one fragrance or colorant and optionally can include between about 0.01% and 10%, by weight, of at least one stability component. The concentrated sprayable ambient flavor composition can include between about 0% and about 0.1%, by weight, of a microbiocide, and more preferably, it can include between about 0.03% and about 0.1 % by weight of microbiocide. In a further example, sprayable compositions consist essentially of the components listed above.
[038] In yet a further embodiment, the sprayable composition consists of a concentrated sprayable window glass cleaning composition. The concentrated sprayable window glass cleaning composition can include water, a solvent, a surfactant, optionally at least one fragrance or colorant, at least one of PEO, PAA and polyacrylate, and optionally at least one stability component. The concentrated sprayable window glass cleaning composition can have a pH between about 2 and about 11.5. Suitable solvents include ethanol and 1,3-propanediol, both VOC solvents. "VOC" refers to volatile organic compounds, which have been the subject of regulation by different government entities, the most prominent regulations having been established by the California Air Resource Board in its General Consumer Products Regulation. A compound is non-volatile if its vapor pressure is below 0.1 mm Hg at 20°C.
[039] In one embodiment, suitable compositions comprise between about 65% and 98% by weight of water, between about 0.05% and 15% by weight of solvent (such as a VOC solvent or a non-VOC solvent), between about 0.01% and about 10% by weight of surfactant, between about 0.01% and about 0.3% by weight of PEO, PAA or a combination thereof. themselves and, optionally, between about 0.01% and 10%, by weight, of at least one stability component. Suitable compositions may alternatively comprise between about 85% and 95%, by weight, water, between about 0.5% and 10%, by weight, solvent, between about 0.05% and about 10% by weight of surfactant, between about 0.01% and about 0.3% by weight of PEO, PAA or a combination thereof, and optionally between about 0.01% and 10%, in weight, of at least one stability component. The fragrances and/or colorants can be present in an amount between about 0% and about 0.7%, by weight, of the concentrated composition. The anti-mist component of the suitable compositions described above may also include between about 0.01% and 10%, by weight, of at least one stability component.
[040] In an alternative embodiment, the concentrated sprayable window glass cleaning composition has a low concentration of VOCs and/or a relatively high concentration of biobased content. In one example, the concentrated sprayable window glass cleaning composition comprises water, at least one solvent or glycerin, at least one surfactant, optionally, at least one fragrance or colorant, optionally, at least one chelator, optionally, at least one dispersant, at least one of PEO, PAA and polyacrylate, and optionally, at least one stability component.
[041] Suitable surfactants include alkyl polyglycosides. Suitable alkyl polyglycosides include, but are not limited to, alkyl polyglycosides and alkyl polypentosides. Alkyl polyglycosides consist of biologically based nonionic surfactants that have detergent and wetting properties. Commercially available alkyl polyglycosides can contain a mixture of carbon lengths. Suitable alkyl polyglycosides include alkyl polyglycosides that contain short-chain carbons, such as chain lengths of less than C12. In one example, suitable alkyl polyglycosides include C8-C10 alkyl polyglycosides and mixtures of alkyl polyglycosides that contain primarily C8-C10 alkyl polyglycosides. Suitable commercially available alkyl polyglycosides include Glucopon 215 UP available from BASF Corporation. Alkyl polypentosides are commercially available from Wheatoleo. Suitable commercially available polypentosides include Radia® Easysurf 6781, which contains chain lengths of about C8-C10 and is available from Wheatoleo.
[042] Suitable solvents include suitable biobased alternative propylene glycol and 1,3-propanediol. Alternatively, glycerin can be used when a high content biobased cleaner with low VOC content is desired. Glycerin is an unsatisfactory solvent. However, it has been found that glycerin can help a fabric "slide" across the surface of a window and reduce blemishes.
[043] The concentrated window glass cleaning composition may optionally include a laminating agent such as a block copolymer of ethylene oxide and propylene oxide. Suitable laminating agents include Pluronic N-3, available from BASF Corporation. In some situations, it may be desirable to exclude ethylene oxide and propylene oxide block copolymers from the concentrated window glass cleaning composition.
[044] A dispersant can be added to the concentrated sprayable window glass cleaning composition to assist with dispersing water hardness and other non-hard materials such as, but not limited to, total dissolved solids such as sodium salts . Suitable dispersants include sodium polycarboxylates, such as sodium polyacrylate, and acrylate/sulfonated copolymers. In one example, the sodium polycarboxylate or acrylate/sulfonated copolymer has a molecular weight less than about 100,000. In another example, the sodium polycarboxylate or acrylate/sulfonate copolymer has a molecular weight less than about 50,000. In a further example, the sodium polycarboxylate or acrylate/sulfonated copolymer has a molecular weight between about 5,000 and about 25,000. Suitable commercially available polymers include Acusol 460N available from Rohm and Haas and Aquatreat AR-546 available from Akzo Nobel.
Suitable chelators include amino-carboxylates such as, but not limited to, salts of ethylenediamine tetraacetic acid (EDTA) and methyl glycine diacetic acid (MGDA), and tetrasodium salt of dicarboxymethyl glutamic acid (GLDA) . Amino carboxylates can also be in their acid form. Suitable commercially available MGDAs include, but are not limited to, Trilon® M available from BASF. Biologically-based amino carboxylates, such as GLDA, can also be used. Suitable bio-based amino carboxylates can contain at least 40% bio-based content, at least 45% bio-based content, and more preferably, at least 50% bio-based content. For example, suitable commercially available GLDAs include, but are not limited to, Dissolvine® GL-47-S and Dissolvine® GL-38, both available from Akzo Nobel, which contain approximately 50% biobased content.
[046] Suitable concentrations for a concentrated sprayable window glass cleaning composition that has low VOCs include between about 20% and 99.9% by weight of water, between about 0% and about 5 %, by weight, of at least one dispersant, between about 0% and about 10%, by weight, of chelator, between about 0.05% and about 30%, by weight, of solvent or glycerin, between about 0.05% and about 50% by weight of surfactant, between about 0% and about 0.7% by weight of at least one fragrance or colorant, between about 0.01% and about 0.3% by weight of PEO, PAA or a combination thereof, and optionally between about 0.01% and 10% by weight of at least one stability component. The most suitable concentrations include between about 65% and 99.9%, by weight, of water, between about 0.01% and about 5%, by weight, of at least one dispersant, between about 0.05 % and about 5% by weight of chelator, between about 0.05% and about 8% by weight of solvent or glycerin, between about 0.5% and about 20% by weight, of surfactant, between about 0% and about 0.7% by weight of at least one fragrance or colorant, between about 0.01% and about 0.3% by weight of PEO, PAA or a combination thereof, and optionally, between about 0.01% and 10%, by weight, of at least one stability component. Even more suitable concentrations include between about 85% and 99.9%, by weight, of water, between about 0.01% and about 5%, by weight, of at least one dispersant, between about 0. 05% and about 2% by weight of chelator, between about 0.05% and about 2% by weight of solvent or glycerin, between about 1% and about 10% by weight of surfactant, between about 0% and about 0.7% by weight of at least one fragrance or colorant, between about 0.01% and about 0.3% by weight of PEO, PAA or a combination thereof, and optionally, between about 0.01% and 10%, by weight, of at least one stability component. The concentrated sprayable window cleaner can optionally further include between about 0% and 0.05% by weight of laminating agent.
[047] A suitable VOC content of the wearing solution includes less than about 3% VOCs by weight of the wearing solution, less than about 1% VOCs by weight of the wearing solution, or about 0% of VOCs in use solution weight. The low VOC concentrated window glass cleaning composition can also have a relatively high biobased content. In one example, the low VOC concentrated window glass cleaning composition includes at least 49% biobased content. More suitably, the low VOC concentrated window glass cleaning composition includes at least 75%, at least 80%, at least 85%, at least 90% or at least 95% biobased content. Low VOC window glass cleaning compositions are also disclosed in the provisional application entitled "Bio-Based Glass Cleaner" (legal registration number 401367), which was filed on the same date and which is incorporated herein by way of of reference.
[048] It is recognized that the above components may be partially or fully replaced by a comparable bio-based component. Bio-based components are components that are composed, wholly or in significant part, of biological products. The amount of biological components or derivatives is referred to as the bio-based content, which is the amount of bio-based carbon in the material or product expressed as a percentage by weight (mass) of the total organic carbon in the material or product. Biobased content can be determined using ASTM method D6866, entitled Standard Test Methods for Determining the Bio-Based Content of Natural Range Materials Using Radiocarbon and Isotope Ratio Mass Spectometry Analysis. More specifically, the ASTM D6866 method uses radiocarbon dating to measure the amount of new carbon present in a product as a percentage of the total organic carbon by comparing the ratio of Carbon 12 to Carbon 14. The water content of a product does not is included as part of the biobased content as it does not contain carbon. It is observed that the bio-based content is distinct from the biodegradability of the product. Product biodegradability measures the ability of microorganisms present in the disposal environment to completely consume the carbon components within a product within a reasonable amount of time and in a specified environment. In one example, the concentrated cleaning composition includes at least 49% biobased content. More suitably, the concentrated composition includes at least 75%, at least 80%, at least 85%, at least 90% or at least 95% biobased content. Additional Functional Materials
[049] The concentrated sprayable composition may contain other functional materials that provide desired functionalities and properties to the sprayable composition. For the purposes of this application, the term "functional materials" includes a material which when dispersed or dissolved in a use solution/concentrated solution, such as an aqueous solution, provides a beneficial property in a particular use. Examples of functional materials include, but are not limited to: compatible aqueous solvents, sequestrants, metal protectants, dyes/odorants, preservatives and microbiocides. Aqueous compatible solvents
[050] The concentrated sprayable composition may contain a compatible solvent. Suitable solvents are soluble in the aqueous sprayable composition of the invention in usage ratios. Preferred soluble solvents include lower alkanols, lower alkyl ethers and lower alkyl glycol ethers. These materials are colorless liquids with pleasant mild odors, are excellent solvents and coupling agents, and are typically miscible with aqueous spray compositions of the invention. Examples of such useful solvents include methanol, ethanol, propanol, isopropanol and butanol, isobutanol, ethylene glycol, diethylene glycol, triethylene glycol, propylene glycol, dipropylene glycol, ethylene-propylene glycol mixed ethers. Glycol ethers include lower alkyl (CI-S alkyl) ethers which include propylene glycol methyl ether, propylene glycol ethyl ether, propylene glycol propyl ether, dipropylene glycol methyl ether, dipropylene glycol ethyl ether, tripropylene glycol methyl ether, ethylene glycol methyl ether, ethylene glycol ethyl ether, ethylene glycol butyl ether, diethylene glycol methyl ether, diethylene glycol butyl ether, ethylene glycol dimethyl ether, ethylene glycol monobutyl ether and others. The solvent capacity of cleaners can be increased with the use of monoalkanol amines. kidnappers
[051] The concentrated sprayable composition may contain an organic or inorganic scavenger or mixtures of scavengers. Organic sequestrants such as citric acid, alkali metal salts of nitrilotriacetic acid (NTA), EDTA, alkali metal gluconates, polyelectrolytes such as a polyacrylic acid, sodium gluconate, and the like can be used herein.
[052] The concentrated sprayable composition may also comprise an effective amount of a water-soluble organic phosphonic acid that has sequestering properties. Preferred phosphonic acids include low molecular weight compounds that contain at least two anion-forming groups, at least one of which consists of a phosphonic acid group. Such useful phosphonic acids include mono-, di-, tri-, and tetra-phosphonic acids which may also contain groups capable of forming anions under alkaline conditions, such as carboxy, hydroxy, thio, and the like. Among these are phosphonic acids that have the formulas: R 1 N[CH2PO3 H2] 2 or R 2 C(PO 3 H2) 2 OH, where R 1 can be -[(lower)alkylene]N[CH2 PO3 H2] 2 or a third moiety --CH 2 PO 3 H 2; and wherein R 2 is selected from the group consisting of C 1 C 6 alkyl.
[053] Phosphonic acid can also comprise a low molecular weight phosphonopolycarboxylic acid, such as one that has about 2 to 4 carboxylic acid moieties and about 1 to 3 phosphonic acid groups. Such acids include 1-phosphono-1-methylsuccinic acid, phosphonosuccinic acid, and 2-phosphonobutane-1,2,4-tricarboxylic acid.
[054] Other organic phosphonic acids include 1-hydroxyethylidene-1,1-diphosphonic acid (CH 3 C(PO 3 H 2) 2 OH, available from ThermPhos as Dequest® 2010, a 58 to 62% aqueous solution; amino [tri(methylenephosphonic acid)] (N[CH 2 PO 3 H 2 ] 3 ), available from ThermPhos as Dequest® 2000, a 50% aqueous solution; ethylenediamine [tetra(methylene-phosphonic acid)] available from ThermPhos as Dequest® 2041, a 90% solid acid product; and 2-phosphonobutane-1,2,4-tricarboxylic acid available from Lanxess as Bayhibit AM, a 45 to 50% aqueous solution. It will be appreciated that the phosphonic acids mentioned above can also be used in the form of water-soluble acid salts, particularly the alkali metal salts such as sodium or potassium; ammonium salts or alkylol amine salts where the alkylol has 2 to 3 carbon atoms, such as mono-, di- or tri-ethanolamine salts. If desired, mixtures of the individual phosphonic acids or their acid salts can also be used. Additional useful phosphonic acids are disclosed in patent no. U.S. 4,051,058, the description of which is incorporated herein by reference.
[055] The sprayable composition can also incorporate a water-soluble acrylic polymer that can act to condition wash solutions under end use conditions. Such polymers include polyacrylic acid, polymethacrylic acid, acrylic acid-methacrylic acid copolymers, hydrolyzed polyacrylamide, hydrolyzed polymethacrylamide, hydrolyzed acrylamide methacrylamide copolymers, hydrolyzed polyacrylonitrile, hydrolyzed polymethacrylonitrile, hydrolyzed acrylonitrile methacrylamide copolymers, or mixtures thereof. Water-soluble salts or partial salts of these polymers, such as the respective alkali metal (eg sodium or potassium) or ammonium salts can also be used. The weight average molecular weight of the polymers is from about 500 to about 15,000 and is preferably in the range from 750 to 10,000. Preferred polymers include polyacrylic acid, the partial sodium salt of polyacrylic acid or sodium polyacrylate which have weight average molecular weights within the range of 1,000 to 6,000. These polymers are commercially available and methods for their preparation are well known in the art.
[056] For example, commercially available water conditioning polyacrylate solutions useful in the present spray solutions include the sodium polyacrylate solution, Colloid® 207 (Colloids, Inc., Newark, N.J.); the polyacrylic acid solution, Aquatreat®AR-602-A (Alco Chemical Corp., Chattanooga, Tenn.); polyacrylic acid solutions (50-65% solids) and sodium polyacrylate powders (2,100 and 6,000 mw) and solutions (45% solids) available as the Goodrite®°K-700 series from BF Goodrich Co. ; and the sodium or partial sodium salts of polyacrylic acid solutions (m.w. 1000 to 4500) available as the Acrysol® series from Rohm and Haas.
[057] The present sprayable composition may also incorporate scavengers to include materials such as complex phosphate scavengers, which include sodium tripolyphosphate, sodium hexametaphosphate, and the like, as well as mixtures thereof. Phosphates, the hardness sequestering agent component of condensed sodium phosphate works as a water softener, cleaner and detergent builder. Condensed cyclic and linear alkali metal (M) phosphates commonly have a molar ratio of M 2O:P 2O 5 of about 1:1 to 2:1 and greater. Typical polyphosphates of this type consist of sodium tripolyphosphate, sodium hexametaphosphate, preferred sodium metaphosphate, as well as the corresponding potassium salts of these phosphates and mixtures thereof. Phosphate particle size is not critical and any commercially available finely divided or granular product can be employed.
[058] Sodium tripolyphosphate is another inorganic hardness sequestering agent. Sodium tripolyphosphate acts to sequester calcium and/or magnesium cations, providing water softening properties. It contributes to the removal of dirt from hard surfaces and keeps dirt in suspension. It has little corrosive action on common surface materials and is low in cost compared to other water conditioners. Sodium tripolyphosphate has relatively low solubility in water (about 14% by weight) and its concentration needs to be increased using different solubility media. Typical examples of such phosphates being alkaline condensed phosphates (i.e. polyphosphates) such as sodium or potassium pyrophosphate, sodium or potassium tripolyphosphate, sodium or potassium hexametaphosphate, etc. Metal protectors
[059] The sprayable composition may contain a material that can protect the metal from corrosion. Such metal protectants include, for example, sodium gluconate and sodium glucoheptonate. Dyes/Odorants
[060] Various colorants, odorants, which include perfumes, and other aesthetic optimizing agents can also be included in the compositions. Examples of suitable commercially available dyes include, but are not limited to: Direct Blue 86, available from Mac Dye-Chem Industries, Ahmedabad, India; Fastusol Blue, available from Mobay Chemical Corporation, Pittsburgh, PA; Acid Orange 7, available from American Cyanamid Company, Wayne, NJ; Basic Violet 10 and Sandolan Blue/ Acid Blue 182, available from Sandoz, Princeton, NJ; Acid Yellow 23, available from Chemos GmbH, Regenstauf, Germany; Acid Yellow 17, available from Sigma Chemical, St. Louis, MO; Sap Green and Metanil Yellow, available from Keystone Aniline and Chemical, Chicago, IL; Acid Blue 9, available from Emerald Hilton Davis, LLC, Cincinnati, OH; Hisol Fast Red and Fluorescein, available from Capitol Color and Chemical Company, Newark, NJ; and Acid Green 25, Ciba Specialty Chemicals Corporation, Greenboro, NC.
[061] Examples of suitable fragrances or perfumes include, but are not limited to: terpenoids such as citronellol, aldehydes such as amyl cinnamaldehyde, a jasmine such as CIS-jasmine or jasmal, and vanillin. Surface Chemistry Modifiers
[062] Various surface chemistry modifiers can be incorporated into the concentrated sprayable composition. Examples of suitable commercially available surface chemistry modifiers include Laponite® silicates available from Southern Clay Products, Inc. Surface chemistry modifiers can have high surface free energy and high surface area that lead to interactions with many types of organic compounds. In one example, suitable surface chemistry modifiers have a free surface energy of about 200 mjoules/meter2 and a surface area between about 750 and 800 m2/gram. A suitable concentration range for surface chemistry modifiers in the use solution is between about 10 ppm and about 100 ppm. Solution for use
[063] The concentrated spray composition can be diluted with water, known as dilution water, to form a use solution. In general, a concentrate refers to a composition that is intended to be diluted with water to provide a use solution; a working solution is dispersed or used without further dilution.
[064] The resulting use solution has a relatively low concentration of anti-mist component. In a suitable use solution, the concentration of PEO is between about 0.002% and about 0.006%, by weight. In another example, the PEO concentration is between about 0.003% and 0.005%. In a further example, the PEO concentration in the concentrated spray solution may be 10 to 200 times greater than the PEO concentration in the use solution.
[065] In another suitable use solution, the concentration of polyacrylamide is between about 0.002% and 0.01% by weight. In a particularly suitable use solution, the concentration of polyacrylamide is between about 0.003% and about 0.007% by weight.
[066] In an additional suitable use solution, the concentration of PEO, PAA or a combination thereof is between about 0.002% and about 0.006% by weight. In another example, the concentration of PEO, PAA or a combination thereof is between about 0.003% and 0.005%. In a further example, the concentration of PEO, PAA or a combination thereof in the concentrated spray solution may be 10 to 200 times greater than the PEO concentration of the use solution.
[067] As discussed above, the anti-mist component may alternatively be polyacrylate. In a suitable use solution, the polyacrylate concentration is greater than about 0.1% by weight. In another example, the polyacrylate concentration is between about 0.2% and about 5.0% by weight. In a further example, the concentration of polyacrylate is between about 0.3% and about 3.0% by weight.
[068] The resulting use solution may also have a relatively low stability component concentration. In a suitable use solution, the concentration of stability component is between about 0.003% and about 10%, by weight.
[069] As discussed above, the concentrated spray composition may include an acid. The acid can be present in a sufficient amount such that the solution has a pH of 4.5 or less. In one example, a suitable acid concentration in the wearing solution is between about 0.1% and 10% by weight of the wearing solution. The amount of acid present in the use solution may depend on whether the acid is a strong acid or a weak acid. Strong acids may have a greater tendency to lose protons such that a smaller amount of strong acid is needed to reach the same pH compared to a weak acid. In one example, the use solution contains from about 0.1% to about 1% strong acid. In another example, the use solution contains between about 1% and about 10% weak acid.
[070] The use solution can be dispensed with the use of an aerosol spray or transient stock trigger spray (i.e. non-low speed trigger), which results in limited flotation, mist, and/or atomization of the solution for aqueous use. Example transient stock trigger sprayers include, but are not limited to, the 1.66 HP Calmar Mixor trigger sprayer. The reduction in flotation, haze and atomization can be determined from the droplet size of the applied solution, with an increased droplet size indicating reduced haze and atomization. The increased droplet size also reduces inhalation of the use solution. It is preferred that the average droplet size is about 10 microns or larger, about 50 microns or larger, about 70 microns or larger, about 100 microns or larger, about 150 microns or larger, and preferably about 200 microns or greater. There are several methods for determining droplet size including, but not limited to, adaptive high-speed cameras, laser diffraction, and phase Doppler particle analysis. Commercially available laser diffraction apparatus include Spraytec available from Malvern and Helos available from Sympatec.
[071] When the use solution containing the anti-mist component is dispersed with a transient trigger spray, the resulting droplet size is increased compared to the same spray solutions that do not contain the anti-mist component. A suitable use solution containing the anti-mist component and sprayed with a stock spray results in less than about 0.5% droplets with a droplet size below 11 microns, and more particularly less than about 0. 4% droplets with a droplet size below 11 microns, and more particularly less than 0.1% of droplets with a droplet size below 11 microns. In one example, an unmodified ready-to-use solution had 1.3% droplets below 11 microns, while the same ready-to-use solutions modified with 0.003% polyethylene oxide had 0.65% droplets below 11 microns when dispersed with the same transient spray trigger.
[072] The use solution can also be dispensed with using a low speed trigger sprayer such as the one available from Calmar. A typical transient trigger sprayer includes a discharge valve at the discharge nozzle end of a discharge passage. A resilient element, such as a spring, keeps the discharge valve seated in a closed position. When the fluid pressure at the discharge valve is greater than the strength of the resilient element, the discharge valve opens and disperses the fluid. A typical dump valve on a stock trigger sprayer consists of a regulating valve that allows the user to control the actuation rate of the trigger sprayer. The discharge valve actuation rate determines the flow velocity, and a higher velocity results in smaller droplets. A low-speed trigger sprayer may contain a two-stage pressure build-up discharge valve assembly that regulates the speed of the operator's pumping stroke and produces a well-defined particle size. In one example, the two-stage pressure build-up relief valve may include a first valve that has a high pressure threshold and a second valve that has a lower pressure threshold so that the discharge valve opens and closes with pressure at the beginning and end of the pumping process. Exemplary low speed trigger sprayers are commercially available from Calmar and are described in patent no. U.S. 5,522,547 to Dobbs and patent no. U.S. 7,775,405 to Sweeton, all of which are incorporated in their entirety herein. Low speed trigger sprays can result in less fluctuation, mist and atomization of the use solution, and can reduce the amount of small droplets dispensed. The sprayable composition containing an anti-mist component can act synergistically with the low velocity trigger spray to produce a greater increase in droplet size than would be expected based on the components alone. In one example, a stock solution containing the anti-mist component sprayed with a low velocity trigger spray resulted in 0% droplets with a droplet size below 11 microns.
[073] The use solution consists of a non-newtonian liquid. When not under tension, the use solution has a viscosity similar to water. For example, in one modality, the wearing solution has a viscosity less than about 40 centipoise.
[074] As discussed above, the anti-mist component can increase the droplet size of the wearing solution when dispensed. The anti-mist component can also increase the average flight distance of the wearing solution when dispensed from a trigger sprayer. Increasing the average flight distance allows a user to move further away from the target hard surface and can decrease the likelihood of inhaling particulates, particularly particulates that bounce off the hard surface. Modalities
[075] The present invention relates to concentrated aqueous spray compositions that include an anti-mist component, such as polyethylene oxide and polyacrylamide, and solutions for using the same. The concentrated spray composition of the present invention can be diluted with diluting water to form a wearing solution, which can be applied to a surface to remove the subject using a spray device.
[076] Exemplary ranges for sprayable composition components, when supplied as a concentrated acid cleaner, a concentrated high acid cleaner, a concentrated neutral quaternary cleaner, a concentrated ambient flavor and a concentrated glass window cleaner, are provided in Tables 1 to 6, respectively. Tables 1 to 6 provided exemplary ranges when the anti-mist component consists of PEO, PAA or combination thereof and when the anti-mist component consists of polyacrylate. Table 1- Composition of Concentrated Acid Cleaner

[077] The concentrated acid cleaner composition of Table 1 can be diluted with water to about 5% to 15% concentrate to form a use solution. For example, the concentrated acid cleaner use solution of Table 1 can have a concentration of PEO, PAA or a combination thereof between about 0.002% and about 0.006% by weight. Suitable acid concentrations in the wear solution include from about 0.1% to about 10% by weight of the wear solution. Table 2 - Concentrated Highly Acid Cleaner Composition I

[078] The concentrated highly acidic cleaner composition of Table 2 can be diluted with water to about 5% to 15% concentrate to form a wear solution. For example, the concentrated acid cleaner use solution of Table 2 can have a concentration of PEO, PAA or a combination thereof between about 0.002% and about 0.006% by weight. Suitable acid concentrations in the wear solution include from about 0.1% to about 10% by weight of the wear solution. Table 3 - Concentrated High Acid Cleaner Composition II

[079] Suitable nonionic surfactants may consist of branched or unbranched ethoxylated amine according to one of the following formulas:

[080] R can be an alkylaryl or linear or branched alkyl substituent. R can be a substituent having from 1 to 24 carbon atoms and each n can be from 1 to 20. R can be derived from coconut oil and n can be between 1 to 14, preferably between 6 to 12 and having an HLB from approximately 10 to 14, where HLB represents the empirical expression for hydrophilic and hydrophobic groups of the surfactant, and the higher the HLB value, the more water soluble the surfactant is. In a suitable branched ethoxylated amine, the total EO groups (n + n) are preferably between 6 to 12 or 6 to 10. In another suitable ethoxylated amine, R may be terminated or terminated with ethylene oxide, oxide units of propylene or butylene oxide. A suitable CAS number for an ethoxylated amine might be 61791-14-8.
[081] The nonionic surfactant can be a medium to short chain carbon group that has fewer than 24 carbon atoms that does not include an alcohol. The ethoxylated amine can also consist of a cocoamine. Ethoxylated cocoamines are commercially available, for example, under trade names such as Varonic (Evonik Industries) and Toximul (Stepan Company), which include Varonic K-210 and Toximul CA 7.5.
[082] The concentrated highly acidic cleaner composition of Table 3 can be diluted with water to form a use solution that has an acid concentration, which includes a fatty acid antimicrobial agent, of between about 1% and about 10% , by weight. In another example, the acid scavenger concentration use solution of Table 3 may have a concentration of PEO, PAA or a combination thereof between about 0.002% and about 0.006% by weight. Table 4 - Concentrated neutral quaternary cleaner composition

[083] The concentrated neutral quaternary cleaner composition of Table 4 can be diluted with water to about 0.1% to 0.5% concentrate to form a wear solution. In one example, the use solution of the concentrated neutral quaternary cleaner composition of Table 4 may have a concentration of PEO, PAA or a combination thereof between about 0.002% and about 0.006%, by weight. The use solution of the concentrated neutral quaternary cleanser composition can have a pH of between about 5 and about 11. Table 5 - Concentrated Ambient Flavor Composition

[084] The concentrated ambient flavor composition of Table 5 can be diluted with water to about 3% to 10% concentrate to form a use solution. Table 6 - Concentrated Window Glass Cleaning Composition

[085] The concentrated window glass cleaning composition of Table 6 can be diluted with water to about 0.5% to 10% concentrate to form a use solution. The use solution can have a pH between about 3 and about 10.
[086] The concentrated compositions shown above in Tables 1 to 6 can be further concentrated to further reduce the amount of water required to be transported and stored. In one example, the concentrated compositions in Tables 1 to 6 are concentrated 2 to 4 times. For example, PEO and/or PAA can be present in an amount between about 0.02% to about 1.2%, by weight, of the composition, and the polyacrylate can be present in an amount between about 0.5 % to about 30% by weight of the concentrated composition. The stability component can be present in concentrations of up to about 20% by weight or up to about 40% by weight of the concentrate composition. EXAMPLES

Example 1 - Stretch Viscosity
[0110] The elongation resistance can be measured with devices such as those described in R.W. Dexter, Atomization and Sprays, vol. 6, pages 167 to 197, 1996, which is incorporated herein by reference. The apparatus used to measure the elongation viscosity in Example 1 comprised five 100 mesh screens tightly packed on top of one another at the base of a 50 ml burette containing a measurable amount of liquid. The mesh screens were contained in an adapter and tubing positioned at the base of the burette. The burette was 74 cm long and had a diameter of 1.5 cm. The adapter and tubing were 10.5 cm long, and the mesh screens (i.e., the area available for flow through the adapter and tubing) were 1.2 cm in diameter. The liquid was forced through the tortuous path formed by many fine holes. The time taken for 50 ml of a liquid to flow through the apparatus was measured and correlated with a shear viscosity. The longer the time taken to flow through the packed bed of the mesh, the more strength and therefore the greater the elongation viscosity.
[0111] Aqueous solutions comprising Polyox WSR 301 or xanthan gum were prepared according to Table 6, and the time required for 50 grams of the aqueous solution to flow through the apparatus was measured. Table 6

[0112] As shown in Table 6, samples containing Polyox WSR 301 took longer to flow through the apparatus, while having similar shear viscosities to water. In comparison, the shear viscosity of sample 6, which contained xanthan gum, was higher than that of water. The increased time to flow through the apparatus indicated an increased stretch viscosity.
[0113] Samples 2 to 5, which include Polyox, have a viscosity similar to that of water and a greater elongation viscosity than water. Increased elongation viscosity can result in increased droplet size and reduced haze. In comparison, xanthan gum produced a composition that has significantly increased shear viscosity and elongation viscosity. Due to the fact that xanthan gum results in increased shear viscosity and elongation viscosity, xanthan gum would result in a concentrated composition that is too thick for use. Example 2 - Stability test
[0114] Several concentrated aqueous spray solutions were tested to determine their temperature stability. Concentrated spray solutions were tested at room temperature (20° Celsius to 25° Celsius), 120° Fahrenheit (48.88° Celsius), 4° Celsius. Observations were made after 96 hours, 240 hours, 336 hours and 4 weeks. Concentrated spray solutions were also exposed to freeze-thaw cycles, in which the solutions were frozen and then allowed to thaw at room temperature. The solutions were exposed to four cycles of total freezing and thawing and observations were made after each cycle. Sample 7
[0115] For sample 7, polyethylene oxide was added to Oasis 299 concentrate. The component concentrations of the solutions are shown below in Table 7. Table 7

[0116] There was no visually noticeable change in elongation viscosity or other visually observable property for Sample 7 stored at 120° Fahrenheit (48.88° Celsius), 4° Celsius, and room temperature after 96 hours, 240 hours, 336 hours and 4 weeks. After three freeze/thaw cycles, Sample 7 contained phantom tails that disappeared after inverting the solution. Similar phantom tails were observed after the four freeze/thaw cycle of Sample 7, and these phantom tails disappeared after two rotations of the solution. Phantom tails can be caused by the decreased solubility of one of the components due to a decrease in temperature. Particulates disappeared after mechanical disturbance (such as mixing) or returning the solution to room temperature. Sample 8
[0117] For Sample 8, polyethylene oxide was added to the window cleaner concentrate A of Table A. Sample 8 component concentrations are shown below in Table 8. Table 8

[0118] After 96 hours, 240 hours, 336 hours and four weeks at 120° Fahrenheit (48.88° Celsius), 4° Celsius and room temperature, no noticeable change in elongation viscosity or other visually observable property was visually observed for to Sample 8. No notable changes were observed after one and two freeze/thaw cycles of Sample 8. After three freeze/thaw cycles of Sample 8, phantom tails were present, but disappeared after solution inversion. Similar phantom tails were observed after the fourth freeze/thaw cycle of Sample 8, and these phantom tails disappeared after two rotations of the solution. Sample 9
[0119] For Sample 9, polyethylene oxide was added at 0.001 to 0.05% to a ready-to-use solution of Lemon-Lift. Polyethylene oxide appeared to be rapidly degraded and Sample 10 did not pass stability tests. Example 3 - Spray tests Comparative samples A and B
[0120] Ready-to-use solutions were formed from concentrated Samples 7 and 8. The ready-to-use solutions were sprayed with a trigger sprayer available from Calmar and the mist or aerosol produced by each sample was observed. After four weeks of storage at the specified temperature or four freeze/thaw cycles, Concentrated Samples 7 and 8 were returned to room temperature and diluted with water to form ready-to-use (RTU) solutions. The 1.66 HP Calmar Mix or HP trigger sprayer was used to spray each sample onto a hard surface. Calmar Mixor HP is not a low speed sprayer. The spray test results of Samples RTU 7 and 8 were visually compared to Comparative Samples A and B, respectively. Sample RTU 7 was formed by diluting the Sample 7 formulations with water at a dilution ratio of 5 to 15%. Comparative Sample A consisted of a ready-to-use solution of Oasis 299 prepared by diluting Oasis 299 liquid concentrate with water at a dilution ratio of 5 to 15%. Sample RTU 8 was formed by diluting Sample 8 with water to form a solution containing 0.5 to 10% concentrate by weight. Comparative Sample B consisted of a ready-to-use window cleaner concentrate prepared by diluting window cleaner concentrate A with water to form a solution containing 0.5 to 10% window cleaner concentrate A by weight . Visual observations are shown in Table 9 below. Table 9


[0121 ] The addition of polyethylene oxide (Polyox WSR 301) reduced haze in Oasis 299 and window cleaner A. The reduction was observed in samples stored at 4°C, room temperature and in those subjected to freeze/thaw cycles. Samples stored at 120°F (48.88°C) also showed improvement. Samples 10 to 37 and Comparative Samples C, D and E
[0122] Stability components have been investigated to prolong the shelf life of concentrated solutions. A stability component was added to the Oasis 299 concentrate according to Table 10 and the solutions were stored for four weeks at 120°F (48.88°C). All solutions contained concentrated Oasis 299, 0.042% by weight Polyox WSR 301 and the specified stability component. beautiful 10


[0123] After four weeks, the concentrated solutions were removed from the oven and allowed to return to room temperature. The concentrated solutions were then diluted with water to form ready-to-use 5 to 15% concentrated solutions. The ready-to-use solutions were sprayed with stock trigger sprayers and the mist or aerosol of each was observed. The spray test results of Samples 10 to 37 were visually compared to those of Comparative Samples C, D and E. Comparative Sample C consisted of Oasis 299 concentrate containing 0.042% by weight Polyox and stored at room temperature for four weeks. Comparative Sample D consisted of Oasis 299 concentrate containing 0.042% by weight Polyox and stored at 120°F (48.88°C) for four weeks. Comparative Sample E consisted of Oasis 299 concentrate containing 0.042% by weight Polyox and stored in the dark at room temperature for four weeks.
[0124] Samples 10 to 13 and Samples 22 to 25 exhibited reduced haze compared to Comparative Sample D. This suggests that Irganox 5057 and GL-38 enhance the stability of the anti-mist polymer. None of the other Samples significantly reduced haze compared to Comparative Sample D. Samples 38 to 57
[0125] Polyacrylamide was investigated as an anti-mist component and additives were added to investigate the improved shelf life. Samples 38 to 57 included Oasis 299 concentrate, 0.0736% SuperFloc N-300 by weight and an additive according to Table 11. Table 11


[0126] After storage for four weeks at 120°F (48.88°C), the concentrated solutions were removed from the oven and allowed to return to room temperature. The concentrated solutions were then diluted with water to form 5 to 15% RTU solutions concentrated with a SuperFloc N-300 concentration of 0.007% by weight. The RTU solutions from Samples 38 to 57 were sprayed using a stock sprayer and visual observations regarding the mist and aerosol of each can be observed. These visual results were compared with those for the RTU solutions of Comparative Samples C, D and E.
[0127] Samples 38 to 40 and Samples 47 to 49 exhibited reduced haze compared to Comparative Sample D. This suggests that Irganox 5057 and GL-47 enhance the stability of the anti-mist polymer. None of the other Samples significantly reduced haze compared to Comparative Sample D. Example 4 - Droplet Size Samples 58 to 65
[0128] The droplet size distributions of cleaners modified with polyethylene oxide were compared to cleaners that were not modified (ie, did not contain polyethylene oxide). Droplet size distributions were determined using a HELOS apparatus available from Sympatec GmbH, Clausthal-Zellerfeld, Germany. HELOS determines the droplet size by laser diffraction. Droplet size distributions were determined for ready-to-use solutions dispensed with stock trigger sprayers and with low-speed sprayers available from Calmar.
[0129] To analyze the particle size using the Sympatec Helos Particle Size Analyzer, the switch on the Particle Size Analyzer was turned to position no. 2. If the switch was originally in position no. 0, the unit was allowed to stabilize for 30 minutes before testing began. If the switch was originally in position no. 1, stabilization time was not required and the test could be started immediately. The Sympatec Helos particle size analyzer was in communication with a computer that ran software designed to interpret the data from the particle size analyzer.
[0130] The Sympatec Helos Particle Size Analyzer is capable of measuring drop sizes only in certain ranges depending on the lenses used. The desired lens was placed on the particle size analyzer and a reference measurement was performed to calibrate the particle size analyzer.
[0131] A sprayer with the test medium was started. The sprayer was then placed so that the spray hole was 20.32 centimeters (8 inches) from the lens and center of the spray passed through the laser. To conduct the test, the sprayer was actuated three times at 90 strokes per minute using an automatic actuator. Computer software calculated the particle size distributions.
[0132] Samples 58 to 65 consisted of ready-to-use solutions formed by diluting the respective concentrated base cleaning composition with water to form a solution containing the weight percentages indicated in Table 12. Base cleaning compositions modified concentrates were formed by adding a sufficient amount of polyethylene oxide so that, when diluted, the respective ready-to-use solution contained 0.003% polyethylene oxide by weight. Table 12

[0133] Figure 1 illustrates the percentage of droplets below 11 microns for Samples 58 to 65 when dispensed with a 1.66cc output Calmar Mixor HP sprayer (ie, a non-low speed sprayer). As shown in Figure 1, the addition of 0.003% polyethylene oxide decreases the droplet percentage below 11 microns in Oasis 285, Oasis 146, Oasis 299 and Window Cleaner A (W.C). The percentage of particles of 11 microns or above are of interest due to the fact that particles of this size are believed to be more resistant to inhalation in the throat and lungs. On average, the addition of 0.003% polyethylene oxide significantly decreased the percentage of droplets below 11 microns in Oasis 285, Oasis 146, Oasis 299 and window cleaner A by 53%.
[0134] Figure 2 illustrates the average droplet size for each stock and modified solution when applied with a 1.66 cc output Calmar Mixor HP sprayer (ie, a non-low velocity sprayer). The addition of 0.003% polyethylene oxide increased the average droplet size in Oasis 285, Oasis 146, Oasis 299 and window cleaner A (W.C.) by an average of 28%.
[0135] Figure 3 illustrates the average droplet size for each stock and modified solution when applied with a low speed trigger sprayer available from Calmar. The addition of 0.003% polyethylene oxide increased the droplet size on average by 157.8% for all products tested. Example 5 - Stability test Samples 66 to 88 and Comparative Samples F, G and H
[0136] The purpose of this experiment was to observe the rate of degradation of the effectiveness of high molecular weight PEO through a drop in shear viscosity over time with the use of a Brookfield viscometer. Samples 66 to 88 were formed by adding the stability additive specified in Table 13 to the concentrated highly acidic scavenger A of Table B above. Additional Polyox WSR 301 was also added so that the resulting formulations contained 0.2% Polyox WSR 301. The concentration of Polyox WSR 301 was chosen so that the resulting formulation had a relatively higher viscosity than water. The high concentration of Polyox WSR 301 was only chosen in order to allow observance of the degradation rate and produced an undesirably thick solution. Table 13


[0137] Viscosities of the concentrated solutions were measured with a DV-II+ viscometer available from Brookfield before storage and after storage for 5 days, 10 days, 18 days, 24 days and 32 days at 120°F (48.88 °C) and at room temperature. To measure viscosity, the samples were allowed to stabilize at room temperature (about 72°F (22.22°C)) and then tested with a Brookfield viscometer using the RV-2 spindle at 2 RPM and time to 5-minute settling between samples. The ratio of viscosity after storage to original viscosity was calculated for each sample ((viscosity after storage / original viscosity)* 100%) and are shown in Table 14. Table 14


[0138] The results were compared with Comparative Samples F, G and H. Comparative Sample F consisted of Highly Acid Cleaner A containing 0.2% by weight Polyox and stored at room temperature for four weeks. Comparative Sample G consisted of Highly Acid Cleaner A containing 0.2% by weight Polyox and stored at 120°F (48.88°C) for four weeks. Comparative Sample H consisted of Highly Acid Cleaner A containing 0.2% by weight Polyox and stored in the dark at room temperature for four weeks. After storage for 32 days, Samples 70 and 74 and Comparative Samples F and H had a viscosity ratio greater than 50%. A reduction in viscosity (ie, a low viscosity ratio) may indicate Polyox degradation. Samples 89 to 94 and Comparative Sample I
[0139] The polymer degradation rate for compositions that include a combination of antioxidants and chelators has also been investigated. Concentrated samples included 0.044% by weight of Polyox WSR 301 and the additive specified below in concentrated highly acidic acid cleaner A. Table 15


[0140] Concentrated samples were formed by mixing Polyox WSR 301 and Stability Additive with Glucopon High Acid Cleaner A for about 10 minutes. The Polyox Stability Additive, Glucopon blend was then blended with the remaining ingredients of High Acid Acid Cleanser A for 10 minutes. Samples were allowed to settle overnight at room temperature and then stored at 120°F (48.88°C). After a period of storage, the samples were removed from the oven, returned to room temperature. A stock solution containing 0.004% by weight of Polyox WSR 301 was created by diluting a portion of the sample with water. Use solutions were sprayed with stock trigger sprayers and spray patterns were qualitatively observed. Spray patterns were ranked based on the mist or aerosol observed in the air and the percentage of cleaner contacting the substrate surface, with the best spray patterns having less mist observed and a greater amount of cleaner contacting the substrate .
[0141 ] After five days of air storage at 120°F (48.88°C), Samples 89 to 94 had better spray patterns than Comparative Sample I, and Samples 92 and 93 had the best spray pattern . Similarly, after fourteen days of storage at 120°F (48.88°C), Samples 89 to 94 had better spray patterns than Comparative Sample I, and Samples 92 and 93 produced the most preferred spray patterns. Example 5 - Polyacrylate Test Samples 95 to 98
[0142] The purpose of this experiment was to assess the effectiveness of polyacrylate as an anti-mist component. Aquatreat AR-7-H was added to the water in accordance with Table 16 to form use solutions that were sprayed using a stock trigger sprayer. Table 16

[0143] All use solutions had a viscosity comparable to that of water (based on visual observation) and homogenized in about 1 minute or less to form a clear colorless solution. Reduced haze was visually observed for Sample 95. Sample 99
[0144] Sample 99 consisted of a concentrate composition formed by mixing 25 grams of Aquatreat AR-7-H with 75 grams of water to form a 4% active polyacrylate concentrate. Sample 99 had a viscosity comparable to that of water (based on visual observation) and consisted of a clear, colorless solution. Example 6 - Distance Test Samples 100 to 102 and Comparative Sample J
[0145] Tests were conducted to investigate the effect of Polyox on the average flight distance of a wearing solution when dispensed with a stock trigger spray using Dietzgen Diazo paper, which turns blue when exposed to ammonia .
[0146] Firstly, the concentrations of water and Polyox were formed according to Table 17 below. Ammonium hydroxide in an amount of 2.5% by weight was also added to each sample. Solutions have been added to stock trigger sprayers.
[0147] Next, the Diazo paper was laid out along a horizontal surface and the stock trigger spray was placed on one end of the paper so that, when dispensed, the horizontal flight distance of the sample was parallel with the length of the paper. The solution was dispensed by squeezing the trigger sprayer. Due to the fact that the samples included ammonia, the paper turned blue when it came into contact with the sample and the horizontal flight distance of each droplet was visible. The droplet with the far horizontal flight distance was determined and measured. The test was repeated two additional times and the furthest horizontal flight distance of each test was averaged. The results are shown in Table 17. Table 17

[0148] As shown in Table 17, Polyox increased the flight distance of the samples compared to Comparative Sample J, which did not include Polyox.
[0149] Several modifications and additions can be made to the exemplary modalities discussed, without deviating from the scope of the present invention. For example, although the embodiments described above refer to particular features, the scope of this invention also includes embodiments that have different combinations of features and embodiments that do not include all of the features described above.
