BACKGROUND 1. FIELD OF THE INVENTION:
[001] The process (s), procedures (s), method (s), product (s), result (s) and / or inventive concept (s) presently described and / or claimed (collectively referred to below as "inventive concept (s) presently described and / or claimed") refers, in general, to personal care cleaning compositions such as shampoos and liquid soaps. More particularly, but not by way of limitation, the inventive concept (s) presently described and / or claimed still refers to sulfate-free or substantially sulfate-free personal care cleaning compositions. 2. BACKGROUND OF THE INVENTION:
[002] Personal care cleaners, such as shampoos, liquid soaps and liquid hand soaps, typically employ sulfate-based surfactant systems (such as, but not limited to, sodium lauryl sulfate and sodium lauryl sulfate sodium) due to its effectiveness in foaming and stability, and in depositing conditioners / health aids on a target substrate such as hair or skin. It is believed that such deposition occurs through polymer-surfactant complexes, known as coacervates, which are formed after dilution with water. The conditioners / health aides are trapped by the coacervates, which precipitate out of the solution for deposition on the substrate, thus releasing the conditioners / health aids. Personal care cleaners containing sulphate-based surfactants are also, in general, easy to thicken with typical thickeners, such as salts and cellulose-based materials.
[003] However, many believe that sulfate-based surfactants are aggressive to the hair and irritating to the skin. In particular, many believe that sulfate-based surfactants cause an increase in color fading and dryness of the hair, as well as a dryness of the scalp, which can lead to dandruff. The main challenges in the use of sulfate-free surfactants are: 1) difficulty in thickening, 2) weak foam and foam stability, 3) low deposition of conditioners / health aids, 4) low sharpness, and 5) low cleaning. Based on this, the use of sulfate-free surfactants in personal care cleaners typically results in higher costs due to the higher costs of sulfate-free surfactants and the need to use more of these to achieve the same effectiveness as the surfactants based on sulfate.
[004] Therefore, there is a need for an improved personal care cleaner, which uses a sulfate-free surfactant (s) and which is economical and more effective, or at least as effective as sulfate-based cleaners. BRIEF DESCRIPTION OF THE FIGURES

In one respect, R22 is methyl. In another aspect, Q is chloride.
[063] Other optional silicone fluids are insoluble silicone gums. These gums are polysiloxane materials with a viscosity of 25 ° C, greater than or equal to 1,000,000 centistokes (1 m2 / s). Silicone gums are described in U.S. Patent No. 4,152,416; Noll and Walter, "Chemistry and Technology of Silicones", New York: Editora Acadêmica, 1968; in the sheets for General Electric Silicone Rubber SE 30, SE 33, SE 54 and SE 76 products, all of which are incorporated by reference. Silicone gums typically have a molecular weight mass in excess of about 200,000 Daltons, generally between about 200,000 to about 1,000,000 Daltons, specific examples of which include polydimethylsiloxane / polydimethylsiloxane / methylvinylsiloxane copolymer, polydimethylsiloxane / diphenyl copolymer siloxane / methylvinylsiloxane and mixtures thereof.
[064] Another category of non-volatile insoluble silicone fluid conditioning agents are high refractive index polysiloxanes, with a refractive index of at least about 1.46 in one aspect, at least about 1.48 in another. aspect, at least about 1.52 in one more aspect, and at least about 1.55, yet, in an additional aspect. The refractive index of the polysiloxane fluid will generally be less than about 1.70; typically less than about 1.60. In this context, polysiloxane "fluids" include oils as well as gums.
[065] The high refractive index of the polysiloxane fluid includes those represented by the general formula defined by the polyalkyl, polyaryl and polyalkylaryl siloxanes described above, as well as the cyclic polysiloxanes (cyclomethicone) represented by the formula:
where the substituent R20 is as defined above, and the number of repeated units, k, varies from about 3 to about 7 in one aspect, and from 3 to 5 in another aspect. The high refractive index of the polysiloxane fluids may contain an amount of aryl containing sufficient R20 substituents to increase the refractive index to the desired level, which is described above. In addition, the R20 and k should be selected so that the material is non-volatile. Aryl-containing substituents include those containing alicyclic and heterocyclic five- and six-membered aryl rings and those containing fused five- or six-membered rings. Aryl rings can be replaced or not replaced. Substituents include aliphatic substituents and may also include alkoxy substituents, acyl substituents, ketones, halogens (eg, Cl and Br), amines, among others. Examples of aryl-containing groups include substituted and unsubstituted arenes, such as phenyl and phenyl derivatives, such as phenyl with C1-C5 alkyl or alkenyl substituents, for example, allylphenyl, methyl phenyl and ethyl phenyl, vinyl phenis such as styrene and phenyl alkynes (e.g., C2-C4 phenyl alkynes). Heterocyclic aryl groups include substituents derived from furan, imidazole, pyrrole, pyridine, etc. Substitutes for fused aryl rings include, for example, naphthalene, coumarin and purine.
[066] The high refractive index of polysiloxane fluids will exhibit an aryl degree containing substituents of at least about 15% by weight in one aspect, at least about 20% by weight in another aspect, at least about 25 % by weight in yet another aspect, at least about 35% by weight in yet another aspect, and at least about 50% by weight in an additional aspect, based on the weight of the polysiloxane fluid. Typically, the degree of aryl substitution will be less than about 90% by weight, more typically less than about 85% by weight, and can generally range from about 55% to about 80% by weight of the fluid polysiloxane.
[067] In another aspect, the high refractive index of polysiloxane fluids presents a combination of phenyl or substituted phenyl derivatives. The substituents can be selected from C1-C4 alkyl (for example, methyl), hydroxy and C1-C4 alkylamino (for example, -R24NHR25NH2 where each R24 and R25 group is, independently, a C1-C3 alkyl, alkenyl and / or alkoxy.
[068] When silicones with a high refractive index are used, they can optionally be used in solution with a dispersing agent, such as a silicone resin or a surfactant, to reduce the surface tension to a sufficient amount to improve dispersion. and then improve the shine (after drying) of the hair treated with such compositions. Silicone fluids suitable for use are described in U.S. Patent No. 2,826,551, U.S. Patent No. 3,964,500, U.S. Patent No. 4,364,837, English Patent No. 849,433 and Silicone Compounds, Petrarch Systems, Inc. (1984), all of which are incorporated by reference. High refractive index polysiloxanes are available from Dow Corning Corporation (Midland, Michigan), Huls America (Piscataway, New Jersey) and General Electric Silicons (Waterford, New York).
[069] Silicone resins can be included in the appropriate silicone conditioning agent for use in combination with the personal care cleaning composition, as described above. These resins are cross-linked polysiloxanes. Crosslinking is introduced through the incorporation of trifunctional and tetrafunctional silanes such as monofunctional or difunctional silanes (or both) during the production of the silicone resin.
[070] As is well known in the art, the degree of crosslinking that is required in order to result in a silicone resin will vary according to the specific silane units incorporated in the silicone resin. In general, silicone materials which have a sufficient level of trifunctional and tetrafunctional siloxane monomer units (and therefore a sufficient level of crosslinking) so that they dry to form a rigid or hard film are considered silicone resins. The ratio of oxygen atoms to silicon atoms is indicative of the level of crosslinking in a given silicone material. Silicone materials which have at least about 1.1 oxygen atoms per silicon atom, in general, will be silicone resins here. In one respect, the oxygen: silicon atoms ratio is at least about 1.2: 1.0. Silanes used in the production of silicone resins include monomethyl-, dimethyl-, trimethyl-, monophenyl-, diphenyl-, methylphenyl-, monovinyl- and methylvinyl-chlorosilanes, and terachlorosilanes, with the most commonly used methyl substituted silanes. Silicone resins are offered by General Electric as GE SS4230 and SS4267.
[071] Silicone materials and silicone resins, in particular, are identified according to an abbreviated nomenclature system known to those skilled in the art as "MDTQ" nomenclature. According to this system, silicone is described according to the presence of the various units of siloxane monomers which make up the silicone. Briefly, the symbol M denotes the monofunctional unit (CH3) 3SiO0 / 5; D denotes the difunctional unit (CH3) 2SiO; T denotes the tri-functional unit (CH3) SiOi / 5; and Q denotes the quad- or tetrafunctional SiO2 unit. The main symbol units (for example, M ', D', T 'and Q') denote substituents other than methyl and must be specifically defined for each occurrence. Typical alternative substituents include groups such as vinyl, phenyl, amine, hydroxy, etc. The molar ratios of the different units, both in terms of the symbol subscriptions indicating the total number of each type of unit in the silicone (or an average of these) or with the proportions specifically indicated in combination with the complete molecular weight of the silicone material description according to the MDTQ system. High relative molar amounts of T, Q, T 'and / or Q' to D, D ', M and / or M' in a silicone resin is indicative of the high levels of crosslinking. As discussed earlier, however, the overall level of crosslinking can also be indicated by the ratio of oxygen to silicon.
[072] Examples of silicone resins include, but are not limited to, MQ, MT, MTQ, MDT and MDTQ resins. In one respect, methyl is the substitute for silicone resin. In another aspect, the silicone resin is selected from among MQ resins, in which the M: Q ratio is from about 0.5: 1.0 to about 1.5: 1.0 and the average molecular weight of the silicone is about 1000 to about 10,000 Daltons.
[073] When used with non-volatile silicone fluids having a refractive index below 1.46; the weight ratio of the non-volatile silicone fluid to the silicone resin component, ranges from about 4: 1 to about 400: 1 in one aspect, from about 9: 1 to about 200: 1 in another aspect from about 19: 1 to about 100: 1 in one more aspect, particularly when the silicone fluid component is a polydimethylsiloxane fluid or a mixture of polydimethylsiloxane fluid and polydimethylsiloxane gum as described above. As long as the silicone resin forms a part of the same phase in these compositions as that of silicone fluid, that is, the conditioning agent, the sum of the fluid and resin must be included in the determination of the level of silicone conditioning agent in the composition.
[074] The volatile silicones described above include cyclic and linear polydimethylsiloxanes and the like. Volatile cyclic silicones (cyclomethicone) typically contain about 3 to about 7 silicon atoms, alternating with oxygen atoms, in a cyclic ring structure as described above for non-volatile cyclic silicones. However, each R20 substituent and repeated unit, k, in the formula, must be selected so that the material is non-volatile. Typically, R20 is substituted with two alkyl groups (for example, methyl groups). Volatile linear silicones are silicone fluids, as described above, with viscosities of no more than about 25 mPas. "Volatile" means that the silicone has a measurable vapor pressure, or a vapor pressure of at least 2 mmHg (266.6448 Pa) at 20 ° C. Non-volatile silicones have a vapor pressure of less than 2 mmHg (266.6448 Pa) at 20 ° C. A description of volatile cyclic and linear silicones is found in Todd and Byers, "Volatile Silicon Fluids for Cosmetics", Cosmetics and Toiletries, Volume 91 (1), pages 27-32 (1976), and in Kasprzak, "Volatile silicons", Soap / Cosmetics / Specialty Chemicals, pages 40-43 (December 1986), each incorporated by reference.
[075] Examples of volatile cyclomethicone are D4 cyclomethicone (octamethylcyclotetrasiloxane), D5 cyclomethicone (decamethylcyclopentasiloxane), D6 cyclomethicone and mixtures thereof (for example, D4 / D5 and D5 / D6). Volatile cyclomethicone and cyclomethicone mixtures are commercially available from G.E. Silicons such as SF1173, SF1202, SF1256 and SF1258, Dow Corning Corporation as Dow Corning® 244, 245, 246, 345, 1401 and 1501 fluids. Mixtures of volatile cyclomethicone and volatile linear dimethicone are also contemplated.
[076] Examples of volatile linear dimethicones include hexamethyldisiloxane, octamethyltrisiloxane, decamethyltetra siloxane, dodecamethyl pentasiloxane and mixtures thereof. Volatile linear dimethones and dimethicone mixtures are commercially available from Dow Corning Corporation as Dow Corning® 200 fluid (eg, product names 0.65 CST; 1 CST; 1.5 CST and 2 CST) and Dow Corning® 2- fluid 1184.
[077] Emulsified silicones are also suitable for combination with the personal care cleaning composition, as described above. Typically, silicone emulsions have an average silicone particle size in the composition of less than 30 pm in one aspect, less than 20 pm in another aspect, and less than 10 pm in one more aspect. In one embodiment, the average silicone particle size of the emulsified silicone in the composition is less than 2 pm, and ideally ranges from 0.01 to 1 pm. Silicone emulsions having an average silicone particle size of <0.15 micrometers are generally referred to as microemulsions. The particle size can be measured using a laser light scattering technique, using a 2600D granulometer from Malvern Instruments. Silicone emulsions suitable for use in conjunction with the personal care cleaning composition, as described above, are also commercially available in a pre-emulsified form. Examples of suitable preformed emulsions include DC2-1766, DC2-1784, DC2-1788 emulsions, and DC2-1865 and DC2-1870 microemulsions, all available from Dow Corning. All of these are dimethiconol emulsions / microemulsions. Cross-linked silicone gums are also available in pre-emulsified form, which advantageously facilitates Formulation. Examples of materials are available from Dow Corning as DC X2-1787, which is a cross-linked dimethicone gum emulsion. Other examples of materials are available from Dow Corning as DC X2-1391, which is a crosslinked dimethicone gum micromulsion. Preformed amino functional silicone emulsions are also available from silicone oil suppliers such as Dow Corning and General Electric. In particular, suitable emulsions are amino-functional silicone oils with non-ionic and / or cationic surfactants. Specific examples include the cationic emulsion DC929, cationic emulsion DC939, cationic emulsion DC949 and the nonionic emulsions DC2-7224, DC2- 8467, DC2-8177 and DC2-8154 (all available from Dow Corning). Mixtures of any of the types of silicone above can also be used. Specific examples of suitable amino functional silicones are the silicone amino acids DC2-8220, DC2-8166, DC2-8466 and DC2-8950-114 (all available from Dow Corning) and GE 1149-75, (ex General Electric Silicons). An example of a quaternary silicone polymer useful in conjunction with the personal care cleaning composition, as described above, is material K3474, available from Goldschmidt, Germany.
[078] Other suitable silicone oils include copolyol dimethicone, which is linear or branched dimethylsiloxane (dimethicone) copolymers, modified with alkylene oxide units. The alkylene oxide units can be arranged randomly or as block copolymers. A generally useful class of dimethicone polyols is block copolymers having polydimethylsiloxane blocks and terminal and / or pendant polyalkylene oxide blocks, such as polyethylene oxide blocks, polypropylene oxide or both. Dimethicone copoliois can be water-soluble or insoluble, depending on the amount of polyalkylene oxide present in the dimethicone polymer and can be anionic, cationic or non-ionic.
[079] Water-soluble or water-dispersible silicones can also be used in combination with the personal care cleaning composition, as described above. Such water-soluble silicones contain anionic functionality, cationic functionality and / or appropriate nonionic functionality to make the silicone soluble in water or dispersible in water. In one embodiment, water-soluble silicones contain a main polysiloxane chain in which at least an anionic fraction is grafted. The anionic fraction can be grafted to a terminal end of the polysiloxane base, or be grafted as a pendant side group or both. Anionic group means any hydrocarbon fraction that contains at least one anionic group or at least one group that can be ionized to an anionic group after neutralization by a base. As previously discussed, the quantity of anionic hydrocarbon groups which are grafted onto the silicone chain is chosen so that the corresponding silicone derivative is either water-soluble or water-dispersible after neutralization of the ionizable groups with a base. Anionic silicone derivatives can be selected from existing commercial products or can be synthesized by any means known in the art. Nonionic silicones contain terminal alkylene oxide and / or pendant side chain units (eg, copolyol dimethicone).
[080] Silicones with anionic groups can be synthesized by the reaction between (i) a polysiloxane containing a silicic hydrogen and (ii) a compound containing an olefinic unsaturation that also contains an anionic functional group. An example of such a reaction is the hydrosilylation reaction between poly (dimethylsiloxanes) containing Si-H group (s) and an olefin, CH2 = CHR26, where R26 represents a fraction containing an anionic group. The olefin can be monomeric, oligomeric or polymeric. Polysiloxane compounds that contain pending reactive thio (—SH) group (s) are also suitable for grafting an unsaturated anionic group containing compounds in the poly (siloxane) base.
[081] According to one aspect, anionic monomers containing ethylenic unsaturation are used alone or in combination and are selected from unsaturated linear or branched carboxylic acids. Examples of unsaturated carboxylic acids are acrylic acid, methacrylic acid, maleic acid, maleic anhydride, itaconic acid, fumaric acid and crotonic acid. The monomers can optionally be partially or completely neutralized by the base to form an alkaline, alkaline earth metal and ammonium salt. Suitable bases include, but are not limited to, alkali, alkaline earth (eg, sodium, potassium, lithium, calcium) and ammonium hydroxides. It will be noted that, similarly, the oligomeric and polymeric graft segments formed from the preceding monomers can then be neutralized with a base (sodium hydroxide, aqueous ammonia, etc.) to form a salt. Examples of silicone derivatives which are suitable for use are described in patent applications EP-A-0.582.152 and WO 93/23009. Examples of classes of silicone polymers are polysiloxanes containing repeated units represented by the following structure:
where G1 represents hydrogen, C 1 -C 10 alkyl radical and phenyl; G2 represents C1-10 alkylene; G3 represents an anionic polymeric residue obtained from the polymerization of at least one anionic monomer containing ethylenic unsaturation; j is 0 or 1; t is an integer ranging from 1 to 50; eu is an integer from 10 to 350. In one embodiment, G1 is methyl; j is 1; and G2 is a propylene radical; G3 represents a polymeric radical obtained from the polymerization of at least one unsaturated monomer containing a carboxylic acid group (for example, acrylic acid, methacrylic acid, itaconic acid, fumaric acid, crotonic acid, maleic acid or acotinic acid and the like).
[082] The content of the carboxylate group in the final polymer preferably ranges from 1 mole of carboxylate per 200 g of polymer to 1 mole of carboxylate per 5000 g of polymer. The molecular weight number of the silicone polymer ranges preferably from 10,000 to 1,000,000 and even more preferably from 10,000 to 100,000. Examples of unsaturated monomers containing carboxylic acid groups are acrylic acid and methacrylic acid. In addition, to the carboxylic acid group containing monomers, C1-2 alkyl esters of acrylic acid and methacrylic acid can be copolymerized in the polymeric base. Examples of esters include, but are not limited to, ethyl and butyl esters of acrylic and methacrylic acid. A commercially available silicone-acrylate polymer is marketed by the company 3M under the brand name silicone polymers "Plus" 9857C (VS80 dry). These polymers contain a polydimethylsiloxane base (PDMS) in which repeated units of poly (meth) acrylic acid and the poly (meth) acrylate butyl ester are grafted (through a thiopropylene group). These products can be obtained conventionally by copolymerizing the radical between polydimethylsiloxane functionalized with thiopropyl and a mixture of monomers comprising (meth) acrylic acid and butyl (meth) acrylate.
[083] In another modality, water-soluble copolyol silicone can be represented by copolyol silicone carboxylates represented by the formula:

Representative R32 radicals are: —CH2CH2—, —CH = CH—, —CH = CHCH2— ephylene.

[085] In yet another modality, the water-soluble silicones useful in conjunction with the personal care cleaning composition, as differently described above, can be represented by an anionic copolyol silicone represented by the formula:
where R and R are, independently, —CH3 or a radical represented by: - (CH2) 30 (EO) a (PO) b (EO) c — C (0) —R40— C (0) 0H, subject to condition that both R37 and R38 are not - CH3 at the same time; R40 is selected from a divalent radical —CH2CH2, —CH = CH— and phenylene; R39 is selected from C1 -C5 alkyl or phenyl; in this formula a, b and c are integers that vary independently from 0 to 20; EO is an ethylene oxide residue, for example, - (CH2CH20) -; PO is a propylene oxide residue, for example, - (CH2CH (CH3) 0) -; in this formula o is an integer that ranges from 1 to 200 and q is an integer that ranges from 0 to 500.
[086] Other water-soluble silicones useful in conjunction with the personal care cleaning composition, as described above, are quaternized silicone copolymer polymers. These polymers have an outstanding quaternary nitrogen functional group present and are represented by the formula:
where R41 represents a quaternary substituent - N + R3R4R5X ", where R3 and R4 and R5 are independently selected from hydrogen and straight and branched C1-C24 alkyl and X" represents an appropriate anion to balance the cationic charge on the nitrogen atom ; R42 is selected from C1-10 alkyl and phenyl; R43 is - (CH2) 30 (EO) x (PO) y (EO) z — H, where EO is an ethylene oxide residue, for example, - ( CH2CH2O) -; PO is a propylene oxide residue, for example, - (CH2CH (CH3) 0) -; in this formula a is an integer from 0 to 200, b is an integer from 0 to 200, and c is an integer from 1 to 200; in this formula x, y and z are integers and are independently selected from 0 to 20. In one aspect, anion X “represents an anion selected from chloride, bromide, iodide, sulfate, methylsulfate, sulfonate, nitrate, phosphate and acetate.

[090] In the copolyol modalities defined above, EO and PO residues can be arranged randomly, not randomly or by block sequences.
[091] Dimethicone copoliois are described in U.S. Patent Nos. 5,136,063 and 5,180,843, the descriptions of which are incorporated herein by reference.
[092] In addition, dimethicone copoliois are commercially available under the Silsoft® and Silwet® brands from the General Electric Company (GE-OSi).

[093] The personal care cleaning composition, as described above, can further comprise from about 0.05% to about 3%, by weight of the composition in one aspect, from about 0.08% to about 1.5% in another aspect, and from about 0.1% to about 1% in yet another aspect, of at least one conditioning oil as the conditioning agent, either alone or in combination with other conditioning agents, such as silicones (described above) and the other conditioning agents described below.
[094] Suitable conditioning oils include, but are not limited to, hydrocarbon oils having at least about 10 carbon atoms, such as cyclic hydrocarbons, linear aliphatic hydrocarbon chains (saturated or unsaturated) and aliphatic branched hydrocarbon chains (saturated or unsaturated), including polymers and mixtures thereof. Linear chains of hydrocarbon oils typically contain about 12 to 19 carbon atoms. Branched chains of hydrocarbon oils, including hydrocarbon polymers, typically contain more than 19 carbon atoms.

[097] Cationic polymers are also useful as conditioning agents, alone or in combination with the other conditioning agents described herein. Suitable cationic polymers can be synthetically derived or modified from natural polymers, such as cationically modified polysaccharides. While several of the cationic polymers listed here as appropriate conditioning agents are duplicative of those described above for use in other applications, those skilled in the technology will recognize that many polymers act in multiple functions.
[098] Representative conditioning cationic polymers include, but are not limited to, radical free polymerizable acrylic or methacrylic ester or amide monomers. Copolymers can contain one or more units derived from acrylamides, methacrylamides, diacetone acrylamides, acrylic or methacrylic acids or their esters; vinyl lactams, such as pyrrolidone vinyl or caprolactam vinyl, and vinyl esters.

Example 2 - Coacervate formation test
[107] The deposition performance of basic shampoos containing a cationic polymer can be predicted by the depth and width of the coacervate curve. The coavervate curve can be created by plotting the% transmittance at 600 nm of a shampoo in different dilution ranges. Formulations A-F, I, M, T, V and the commercial formulation were subjected to such a test to form coacervates. 0% transparency was measured at various dilution rates (defined as water volume: formulation volume) using an Agilent Cary 60 UV-vis spectrophotometer.
[108] Formulations were each diluted with water to form samples having a 1: 1 weight (formulation) / weight (water) ratio; 1: 2.5; 1: 5; 1: 7.5; 1:10; 1: 12.5; 1:15; 1: 17.5; 1:20 and 1: 22,5 and individually located in vats for the test. Each sample was individually tested in the spectrophotometer against a vat filled with water by measuring the transmittance at a wavelength of 600 nm.
[109] Figure IA shows the results of such tests for commercial Formulation and Formulations A-E. As can be seen in Figure IA, Formulations B and C show similar coacervate formations when compared to a commercial Formulation, and Formulation A demonstrated effective coacervate formations. Figure 1B shows the results of such tests for commercial Formulation and Formulation F. As can be seen in Figure IB, Formulation F shows comparable coacervate formations when compared to commercial Formulation. Figure 15 shows the results of such tests for Formulations I, M, T and V. Formulations I and T show a minimum transmission of 13.5% (Formulation I) and 6.5% (Formulation T). Example 3 - Combing tests Wet combing tests
[110] Bleached Caucasian human hair was separated into individual hair braids weighing about 3 grams each. For each of the tests, the braids were rinsed with water and 0.2 g of the Formulation per gram of the braid was soaped on the hair braid for thirty seconds, caressing the braid in a descending manner. The braid was then rinsed for thirty seconds with water and 0.2 g of the formulation per gram of the braid was applied to the braid a second time, and soaped for thirty seconds, caressing the braid in a descending manner. The braid was then rinsed again for thirty seconds with water and the excess water was removed by passing the braid between the index and middle fingers.
[111] The total wet combing energy (gf-mm) was then measured using the Instron wet combing procedure. According to the Instron wet combing procedure, each hair braid was soaked in distilled water for 15 minutes. The excess water was removed by passing the braid through the index and middle fingers. The braid was loosened by combing the braid with his hands. The braid was then dipped in distilled water three times to untangle the braid. The excess water was then removed again by passing the braid between the index and middle fingers. The braid was positioned on a hanger and combed with the INSTRON instrument, which uses an Instron tension meter equipped to measure the total force required to comb damp hair. Performance was assessed by the ability of a particular formulation to reduce the required strength. Each of the formulations was tested 3 separate times. Dry combing tests
[112] Bleached Caucasian human hair was separated into individual hair plaits weighing about 3 grams each. For each of the tests, the braids were rinsed with water and 0.2 g of the formulation per gram of the braid was soaped on the hair braid for thirty seconds, caressing the braid in a descending manner. The braid was then rinsed for thirty seconds with water and 0.2 g of the braid formulation per gram was applied to the braid a second time, and soaped for thirty seconds, caressing the braid in a descending manner. The braid was then rinsed again for thirty seconds with water and the excess water was removed by passing the braid between the index and middle fingers.
[113] The total dry combing energy (gf-mm) was then measured using the Instron dry combing procedure. According to the Instron dry combing procedure, each hair braid was soaked for 15 minutes in distilled water. The excess water was removed by passing the braid through the index and middle fingers. The braid was loosened by combing the braid with his hands. The braid was then dipped in distilled water three times to untangle the braid. The excess water was then removed again by passing the braid between the index and middle fingers. The braid is then dried with the dryer to remove any remaining water. The dry braid was positioned on a hanger and combed with the INSTRON instrument, which uses an Instron tension meter equipped to measure the total force required to comb dry hair. Performance was assessed by the ability of a particular formulation to reduce the required strength. Each of the formulations was tested 3 separate times.
[114] Figure 2A shows the averages of the results of such tests for the Commercial Formulation and Formulations A-E. The data in Figure 2A shows that the wet and dry combing performance of Formulations AE were each comparable to that of Formulation commercial.
[115] Figure 2B shows the averages of the results of such tests for the Commercial Formulation and Formulations F and H. The data in Figure 2B shows that the wet and dry combing performance of Formulations F and H were comparable to that of the commercial Formulation .
[116] Figure 16 shows the average wet combing energy results after washing for Formulations I, K, M, T and V. Formulations I and K show the low combing energy of the network while Formulations T and V show improvement in combing. Example 4 - Foam stability tests
[117] The Commercial Formulation and Formulations B, F, I, J, K, L, M, T and V were subjected to foam stability tests using the Krüss Foam Analyzer DFA 100 instrument. The DFA 100 instrument allows formation of foam from liquids and measurement of the height of initial formation and degradation of the foam column over time. Formulation samples were diluted to 10% by weight with deionized water and then tested on the DFA 100 analyzer at a temperature of 25 ° C, for a stirring period of 15 seconds, a measurement time of 616 seconds and with stirring. at 4000 rpm.
[118] The results for the Formulation B tests are shown in Figure 3. As can be seen in Figure 3, Formulation B provides instant foam and acceptable foam stability.
[119] The results for the Commercial Formulation and Formulation F tests are shown in Figure 4. As can be seen in Figure 4, Formulation F provides greater instant foaming and the foam begins to degrade long after the Commercial Formulation .
[120] The photos were then taken from the foam produced for Formulation F and Commercial Formulation after 3 minutes to assess the size of the bubbles. Figures 5 and 6 show the size of the bubbles for Formulation F and Commercial Formulation, respectively. As can be seen from Figures 5 and 6, Formulation F shows much smaller bubble sizes when compared to commercial Formulation, which is indicative of finer foam and improved foam stability.
[121] The results for the Formulation I and J tests are shown in Figure 7. As can be seen in Figure 7, Formulation I provides slightly higher instant foaming and better foam stability than that for Formulation J (without Benecel ™ type E rheology modifier).
[122] The results for the Formulation I and K tests are shown in Figure 8. As can be seen in Figure 8, Formulation I provides greater instant foaming and slightly better foam stability than for Formulation K ( rheology modifier Benecel ™ type K instead of Benecel ™ type E).
[123] The results for the Formulation I and L tests are shown in Figure 9. As can be seen in Figure 9, Formulation I provides greater instant foaming and slightly better foam stability than for Formulation L ( without hydroxypropyl gum and APTAC / acrylamide copolymer).
[124] The results for testing Formulations M, T and V are shown in Figure 12, Figure 13 and Figure 14. Formulation V provides stable foam. Example 5 - Sensory assessment tests
[125] Formulation B and commercial Formulation were separately applied to the hair braids, as described above in Example 3, and the hair braids were subjected to sensory tests.
[126] For the performance of the wet state, the braids were tested for: untangling, combing ability, viscosity, slippery texture, softness and coating.
[127] The wet performance tests were carried out according to the following method: - Use of bleached hair; - Two braids per sample; - Maximum of 10 braids at a time (ie, 5 samples at a time); - Cleaning of the hair braids with 4.5% sodium lauryl sulfate solution (SLS) - wash the braids with shampoo as described above (ie 0.1 g of shampoo / g hair or other treatment); - during the wash with shampoo (treatment) and sensorially evaluate the foam speed, foam structure (large bubbles, creamy foam, etc.), the amount of foam and sensation during massage; - Rinse for 30 seconds with water at 37 ° C and evaluate sensorially the foam speed, foam structure (large bubbles, creamy foam, etc.), the amount of foam and sensation during massage; - After rinsing, sensorially evaluate the wet sensation (including: viscosity, softness, slippery texture, coating) , wet combing ability and detangling; - Position the traits hair in the humidity chamber, in the following condition: T = 23 ° C, RH = 50% for drying overnight.
[128] For the dry state performance, the dry braids were also tested for: shine, untangling, combing ability, lightness, volume, slippery texture, softness, coating and dryness.
[129] The assessment was carried out by six trained lecturers (the assessment must be carried out by at least five people).
[130] The results of the wet state performance tests are shown in Figure 10 and show that Formulation B demonstrated equal or slightly better performance in wet sensory tests when compared to the commercial Formulation. The results of the dry state performance tests are shown in Figure 11 and show that Formulation B demonstrated equal or slightly better performance in dry sensory tests when compared to the commercial Formulation.
