COMPOSITION FOR TREATING HAIR THAT UNDERSTANDS METATHETIZED POLYOL INSATURED ESTERS AND METHOD FOR
HAIR CLEANING [001] FIELD OF THE INVENTION [002] The present invention relates to a hair treatment composition containing an anionic surfactant, an aqueous vehicle, and an oligomer derived from the polyol unsaturated esters metathesis, and methods their use.
[003] BACKGROUND OF THE INVENTION [004] Human hair becomes dirty due to contact with the surrounding environment and the sebum secreted by the scalp. Soiling of the hair makes it feel dirty and acquires an unattractive appearance.
[005] Washing with shampoo cleans hair by removing excess dirt and sebum. However, washing with shampoo can leave hair wet, tangled and, generally, in a state of difficult handling. Once the hair dries, it is often left in a dry, rough, dull or frizzy condition due to the removal of natural hair oils.
[006] Several approaches have been developed to alleviate these post-shampoo problems. One approach is to apply shampoos to hair that try to either clean or condition hair from a single product.
[007] In order to provide hair conditioning benefits in a shampoo base for cleaning, a wide variety of active conditioners has been proposed. However, the inclusion of active contents of conditioning agents in shampoos can result in problems of rheology and stability, causing advantages and

2/57 disadvantages for the consumer in terms of cleanliness, foam profiles, and the effects of bending under weight. Additionally, the rising costs of silicone and the petroleum-based nature of silicone have minimized the desirability of silicone as an active conditioning agent.
[008] Based on the arguments mentioned above, there is a need for an active conditioning agent that can provide conditioning benefits to the hair and can replace, or be used in combination with silicone, or other active conditioning agents to maximize the conditioning activity of compositions for hair treatment. Additionally, there is a desire to find an active conditioning agent that can be derived from a natural source, thereby providing an active conditioning agent derived from a renewable resource. There is also a desire to find an active conditioning agent that is either derived from a natural source or leads to a stable product that comprises a micellar surfactant system.
[009] SUMMARY OF THE INVENTION [010] The present invention relates to a composition for treating hair or hair comprising: (a) from about 0.05% to about 15% of one or more oligomers derived from metathesis unsaturated polyol esters, by weight of said hair treatment composition; (b) from about 5% to about 50% of one or more anionic surfactants, by weight of said composition for hair treatment; and (c) at least about 20% of an aqueous vehicle, by weight of said hair treatment composition.

[021] A. Metatetized oligomer [022] The hair treatment composition can
understand from about 0.05% about 15%, alternatively of fence 0.1% about 10%, and alternatively of about 0.25% a about 5%, one or more oligomers derivatives metathesis of esters
polyol unsaturated, by weight of said composition for hair treatment. Exemplary metatetized polyol esters and their starting materials are disclosed in US patent application No. US 2009/0220443 A1, which is incorporated herein by way of reference.
[023] A metatetated polyol unsaturated ester refers to the product obtained when one or more ingredient (s) based on unsaturated polyol ester is (are) subjected to a metathesis reaction. Metathesis is a catalytic reaction that involves the exchange of alkylidene units between compounds containing one or more double bonds (that is, olefinic compounds) via the formation and cleavage of carbon-carbon double bonds. Metathesis can occur between two equal molecules (often called a self-synthesis) and / or it can occur between two different molecules (often called a cross-metathesis. The self-synthesis can be represented schematically as shown in Equation I:
R ¹ —CH = CH — R ² + R * —CH = CH — R ² θ
R ¹ —CH = CH — R * + R ² —CH = CH — R ² (I) where R ¹ and R ² are organic groups.
6/57 [024] Cross metathesis can be represented schematically as shown in Equation II:
R ¹ —CH = CH — R ² + R ³ —CH = CH — R ⁴ θ
R ¹ —CH = CH — R ³ + R — CH = CH — R ⁴ + R ² -
CH = CH — R ³ + R ² —CH = CH — R ⁴ + R'— CH = CH—
FROG ² —CH = CH — R ² + R ³ —CH = CH — R ³ + R ⁴ -
CH = CH — R ⁴ (II)
1 2 where R1, R ² , R ³ , and R ⁴ are organic groups.[025] When O unsaturated polyol ester comprises molecules that has more than a double bond of carbon- carbon (this is, a polyunsaturated ester of polyol), the
self-synthesis results in the oligomerization of the unsaturated polyol ester. The self-synthesis reaction results in the formation of metathesis dimers, metathesis trimers, and metathesis tetramers. Higher order metathesis oligomers, such as metathesis pentamers and metathesis hexamers, can also be formed by continuous self-synthesis and will depend on the number and type of chains connecting the polyol unsaturated ester material and the number of esters and the orientation of the ester in relation to the establishment.
[026] As a starting material, the unsaturated polyol esters are prepared from one or more unsaturated polyol esters. As used herein, the term unsaturated polyol ester refers to a compound that has two or more hydroxyl groups in which at least one of the hydroxyl groups is in the form of an ester, and in which the ester has an organic group including at least a carbon-carbon double bond. In many embodiments, the unsaturated polyol ester can be represented by the general structure I:
7/57 _m (HO) - R - (O — C — R ') „(O — c— R'% II o where n>1; m ^ 0; p ^ Q; (n + m + p )>2; R is an organic group; R 'is an organic group having at least one carbon-carbon double bond; and R ^z is a saturated organic group. The exemplary modalities of the unsaturated polyol ester are described in detail in the document US 2009/0220443 A1. [027] In many embodiments of the invention, the unsaturated polyol ester is an unsaturated ester of glycerol Sources of unsaturated esters of glycerol polyol include synthesized oils, natural oils (for example, vegetable oils, oils algae, bacterial derived oils, and animal fats), combinations thereof, and the like. Used recycled vegetable oils can also be used. Representative examples of vegetable oils include Argan oil (Argania spinosa), canola oil, seed oil rapeseed, coconut oil, corn oil, cottonseed oil, olive oil, palm oil, peanut oil im, safflower oil, sesame oil, soy oil, sunflower oil, soybean oil with high oleoil content, sunflower oil with high oleoil content, flaxseed oil, palm kernel oil, tung oil, castor oil, rapeseed oils with a high erucic acid content, Jatropha oil, combinations of these, and the like.
Representative examples of animal fats include lard, tallow, chicken / chicken fat, yellow fat,
8/57 fish oil, combinations thereof, and the like. A representative example of a synthesized oil includes such oil, which is a by-product of the manufacture of wood pulp.
[028] Other examples of unsaturated polyol esters include diesters such as those derived from ethylene glycol or propylene glycol, esters such as those derived from pentaerythritol or dipentaerythritol, or sugar esters such as SEFOSE®. Sugar esters like SEFOSE® include one or more types of sucrose polyesters, with up to eight ester groups that could experience the exchange reaction via metathesis. Sucrose polyesters are derived from a natural resource and therefore, the use of sucrose polyesters can result in a positive environmental impact. Sucrose polyesters are polyester materials, having multiple substitution positions around the sucrose backbone along with chain length, saturation, and derivative variables of the fatty chains. Such sucrose polyesters can have an esterification (IBAR) greater than about 5. In one embodiment, the sucrose polyester can have an IBAR of about 5 to about 8. In another embodiment, the sucrose polyester has an IBAR from about 5 to 7, and in another embodiment, the sucrose polyester has an IBAR of about 6. In yet another embodiment, the sucrose polyester has an IBAR of about 8. Since sucrose polyesters are derived from a natural resource, there may be a distribution at IBAR and in chain length. For example, a sucrose polyester that has an IBAR of 6, can contain a mixture mainly of IBAR of about 6, with some IBAR of about 5 and some IBAR of about 7.
9/57
In addition, such sucrose polyesters can have a saturation value or iodine (VI) value of about 3 to about 140. In another embodiment the sucrose polyester can have a VI of about 10 to about 120. In yet another embodiment the sucrose polyester can have a VI of about 20 to 100. In addition, such sucrose polyesters have a chain length of about C12 to C20 but are not limited to these chain lengths.
[029] Non-limiting examples of sucrose polyesters suitable for use include SEFOSE® 1618S, SEFOSE® 1618U, SEFOSE® 1618H, Sefa Soyate IMF 40, Sefa Soyate LP426, SEFOSE® 2275, SEFOSE® C1695, SEFOSE® C18: 0 95, SEFOSE® C1495, SEFOSE® 1618H B6, SEFOSE® 1618S B6, SEFOSE® 1618U B6, Sefa Algodoate, SEFOSE® C1295, Sefa C895, Sefa C1095, SEFOSE® 1618S B4.5, all available from The Procter and Gamble Co. of Cincinnati, Ohio, USA.
[030] Other examples of suitable natural polyol esters can include but are not limited to sorbitol esters, maltitol esters, sorbitan esters, esters derived from maltodextrin, xylitol esters, and other sugar derived esters.
[031] In other embodiments, ester chain lengths are not restricted to C8-C22 or even chain lengths and may include natural esters that come from fat and oil comethesis with both natural and synthetic short chain olefins that provide a polyol ester raw material that can have odd and even chains as well as shorter and longer chains for the self-synthesis reaction. Suitable short chain olefins include ethylene and butene.
10/57 [032] Oligomers derived from the metathesis of unsaturated polyol esters can be further modified via hydrogenation. For example, in certain modalities, the
oligomer can be fence in 60% hydrogenated or more; in certain modalities, fence in 70% hydrogenated or more; in certain modalities, fence in 80% hydrogenated or more; in certain modalities, fence in 85% hydrogenated or more; in certain modalities, fence in 90% hydrogenated or more; and in certain modalities, generally 100% hydrogenated.
[033] In some embodiments, the triglyceride oligomer is derived from soybean oil auto-synthesis. The soy oligomer can include hydrogenated soy polyglycerides. The soy oligomer can also include C15-C23 alkanes, as a by-product. An example of metathesis-derived soy oligomers is the fully hydrogenated DOW CORNING® HY-3050 soy wax, available from Dow Corning.
[034] In other embodiments, the metatetated unsaturated polyol esters can be used as a blend with one or more unmetatized polyol unsaturated esters. Unsaturated polyol esters that are not metatetated can be completely or partially hydrogenated. One such example is DOW CORNING® HY-3051, a blend of HY-3050 oligomer and hydrogenated soybean oil (HSBO), available from Dow Corning. In some embodiments of the invention, the unsaturated polyol unsaturated ester is a glycerol unsaturated ester. Sources of unsaturated glycerol polyol esters include synthesized oils, natural oils (e.g., vegetable oils, algae oils, bacterial derived oils, and animal fats), combinations thereof, and the like. Vegetable oils can also be used
11/57 used recycled. Representative examples of vegetable oils include those listed above.
[035] Other modifications of the polyol ester oligomers may be partial amidation of some fraction of the esters with ammonia or higher organic amines such as dodecylamine or other fatty amines. This modification will alter the total composition of the oligomer but may be useful in some applications that provide increased product lubricity. Another modification can be via partial amidation of a polyamine, providing potential for some pseudo-cationic nature to the polyol ester oligomers. One such example is the DOW CORNING® HY-3200 material. Other exemplary modalities of amidofunctionalized oligomers are described in detail in WO2012006324A1, which is incorporated herein by way of reference.
[036] Polyol ester oligomers can also be further modified by partial hydroformylation of the unsaturated functionality to provide one or more OH groups and an increase in the hydrophilicity of the oligomer.
[037] In specific embodiments, the unsaturated polyol esters metatetized and blends are formulated as emulsions of small particles. An emulsion of the triglyceride oligomer can be prepared using a combination of nonionic, zwitterionic, cationic, and anionic surfactants. In some embodiments, the triglyceride oligomer emulsion may be a combination of nonionic and anionic surfactants. Suitable nonionic emulsifiers include Neodol 1-5. Suitable anionic emulsifiers include alkyl and alkyl ether sulfates having the respective formulas ROSO3Na and RO (C2H4O) xSO3Na. In another embodiment, the unsaturated polyol esters metatetized
12/57 are pre-cast before emulsification and incorporated into the hair treatment composition. In some embodiments of small particle emulsions, the unsaturated polyol esters metatetized have a particle size of about 0.05 to about 35 micrometers, alternatively about 0.1 to about 10 micrometers, and alternatively about 0.1 to about 2 micrometers.
[038] In other embodiments, unsaturated polyol esters and blends can be modified prior to oligomerization to incorporate contiguous terminal branching. Exemplary polyol esters modified prior to oligomerization to incorporate terminal branching are shown in WO2012 / 009525 A2, which is incorporated herein by way of reference.
[039] B. Surfactant [040] The hair treatment composition can comprise a detersive surfactant, which provides cleaning performance to the composition. The detersive surfactant, in turn, comprises an anionic surfactant, amphoteric or zwitterionic surfactants, or mixtures thereof. Various examples and descriptions of detersive surfactants are presented in US Patent No. 6,649,155; US Patent Application Publication No. 2008/0317698 and US Patent Application Publication No. 2008/0206355, which are hereby incorporated by reference in their entirety.

[048] C. Aqueous vehicle [049] Compositions for hair treatment can be in the form of pourable liquids (under ambient conditions). Such compositions will therefore typically comprise a vehicle that is present at a content of about 20% by weight to about 95% by weight, or even about 60% by weight to about 85% , by weight. The vehicle may comprise water, or a miscible mixture of water and organic solvent, and In one aspect it may comprise water with minimal or non-significant concentrations of organic solvent, unless otherwise casually incorporated into the composition as minor ingredients from other components.

Exemplary polyhydric alcohols useful in the present invention include propylene glycol, hexylene glycol, glycerin and propanediol.
[051] D. Additional components [052] The hair treatment composition may additionally comprise one or more additional components known for use in personal care or hair care products, provided that the additional components, on the other hand, do not harm undue product stability, product aesthetics, or product performance. These optional ingredients are, more typically, those described in reference books, such as the CTFA Cosmetic Ingredient Handbook, Second Edition, The Cosmetic, Toiletries, and Fragrance Association, Inc. 1988, 1992. Individual concentrations of these additional components can be found in the range from about 0.001% by weight to about 10% by weight of personal care compositions.

Conditioning agents include materials that are used to provide a certain conditioning benefit to hair and / or skin. Conditioning agents useful in hair treatment compositions typically comprise a water-insoluble, water-dispersible and non-volatile liquid that forms liquid, emulsified particles. Conditioning agents suitable for use in the hair treatment composition are those generally characterized as silicones (for example, silicone oils, cationic silicones, silicone gums, high refractive silicones and silicone resins), organic conditioning oils (for example, oils hydrocarbon, polyolefins and fatty esters) or combinations thereof, or those conditioning agents that otherwise form liquid particles, dispersed in the aqueous surfactant matrix of the present invention.

The particles of the silicone-based conditioning agent can consist of volatile silicone, non-volatile silicone or combinations of these substances. If volatile silicones are present, it will typically have been incidental to their use as a solvent or vehicle for commercially available forms of ingredients based on non-volatile silicone materials, such as gums and silicone resins. The particles of the silicone based conditioning agent can contain a silicone fluid based conditioning agent and also other ingredients, such as a silicone resin to improve the deposition efficiency of the silicone fluid or enhance the shine of the hair.
[059] The concentration of the silicone-based conditioning agent is typically in the range of about 0.01% to about 10%, by weight of the composition, alternatively from about 0.1% to about 8%, alternatively from about 0.1% to about 5%, and alternatively about 0.2% to about 3%. Some non-limiting examples of suitable silicone-based conditioning agents, and optional suspending agents for silicone, are described in the reissued US Patent No. 34,584 and in US Patents No. 5,104,646 and US No. 5,106,609, whose descriptions are hereby incorporated by reference.

[060] The dispersed particles of silicone-based conditioning agent typically have a mean diameter value in the range of about 0.01 micrometer to about 50 micrometers. For application of small particles to the hair, the average volumetric diameters of the particles are typically in the range of about 0.01 micrometer to about 4 micrometers, alternatively from about 0.01 micrometer to about 2 micrometers, and alternatively about 0.01 micrometer to about 0.5 micrometer. For the application of larger particles to the hair, the average volumetric diameters of the particles are typically in the range of about 5 micrometers to about 125 micrometers, alternatively from about 10 micrometers to about micrometers, alternatively from about 15 micrometers to about 70 micrometers, and alternatively from about 20 micrometers to about 50 micrometers.
[061] Reference material on silicones, including sections that discuss silicone fluids, gums and resins, as well as the manufacture of silicones, are found in the Encyclopedia of Polymer Science and Engineering, vol. 15, 2d ed., Pgs. 204 to 308, John Wiley & Sons, Inc. (1989), incorporated herein by reference.

[070] iii. Silicone gums [071] Other silicone fluids suitable for use in the hair treatment composition are insoluble silicone gums. These gums are polyorganosiloxane materials having a viscosity, as measured at 25 ° C, greater than or equal to 1 m ² / s (1,000,000 csk). Silicone gums are described in US Patent No. 4,152,416; Noll and Walter, Chemistry and Technology of Silicones, New York: Academic Press (1968); and in General Electric Silicone Rubber Product Data Sheets SE 30, SE 33, SE 54 and SE 76, all of which are incorporated herein by reference. Specific non-limiting examples of silicone gums for use in hair treatment include polydimethyl siloxane, (polydimethyl siloxane) copolymer (methyl vinyl siloxane), poly (dimethyl siloxane) copolymer (diphenyl siloxane) (methyl vinyl siloxane) and mixtures thereof.
[072] iv. High refractive index silicones [073] Other conditioning agents based on insoluble, non-volatile silicone fluid that are suitable for use in the hair treatment composition are known as high refractive index silicones, which have a refractive index of at least about 1.46, alternatively at least about 1.48, alternatively at least about 1.52, and alternatively at least about 1.55. The refractive index of the polysiloxane fluid should generally be less than about 1.70, typically less than about 1.60. In this context, polysiloxane fluid covers
24/57 oils and gums. The high refractive index polysiloxane fluid includes those represented by the general formula (I) above, as well as cyclic polysiloxanes, such as those represented by the formula (V) below:
R
I ‘-I-si-oV
R where R is as defined above, and n is a number from about 3 to about 7, alternatively from about 3 to about 5.
[074] Polysiloxane fluids with a high refractive index include R substituents containing aryl in an amount sufficient to increase the refractive index to the desired level, which is described herein. Additionally, R and n can be selected so that the material is non-volatile.
[075] Aryl containing substituents include those containing five and six membered alicyclic and heterocyclic aryl rings and those containing five or six membered fused rings. The aryl rings themselves can be replaced or not replaced.
[076] In general, polysiloxane fluids with a high refractive index will have a degree of substituents containing aryl of at least about 15%, alternatively at least about 20%, alternatively at least about 25%, alternatively at least about 35%, and alternatively at least about 50%. Typically, the degree of aryl substituents will be less than about 90%, more generally less than about 85%, alternatively from about 55% to about 80%. In
25/57 some embodiments, polysiloxane fluids with a high refractive index have a combination of phenyl substituents or substituents derived from phenyl, with alkyl substituents, in some embodiments C1C4 alkyl, hydroxyl, or C1-C4 amino alkyl (specifically— R4NHR5NH2 in that each R4 and R ⁵ independently is an alkyl, alkenyl and / or C1-C3 alkoxy).
[077] When silicones with a high refractive index are used in the hair treatment composition, they can be used in solution with a diffusing agent, such as a silicone resin or a surfactant, to reduce surface tension by a sufficient amount to improve spreading thus improving the shine (subsequent to drying) of the hair treated with the compositions.
[078] Silicone fluids suitable for use in the hair treatment composition are disclosed in US Patent No. 2,826,551, US Patent No. 3,964,500, US Patent No. 4,364,837, British Patent No. 849,433, and Silicon Compounds, Petrarch Systems, Inc. (1984), all of which are incorporated by reference.
[079] V. Silicone resins [080] Silicone resins can be included in the silicone-based conditioning agent of the hair treatment composition. Such resins are highly cross-linked polymeric siloxane systems. Crosslinking is introduced through the incorporation of trifunctional and tetrafunctional silanes with monofunctional, difunctional silanes or both, during the manufacture of silicone resin.
[081] Silicone materials and particularly silicone resins can be conveniently identified
26/57 according to a shorthand nomenclature system known to those skilled in the art as MDTQ nomenclature. Under this system, silicone is described according to the presence of the various units of siloxane monomers that comprise it. Briefly, the symbol M denotes the monofunctional unit (CH ₃ ) 3SiO ₀ , ₅ ; D denotes the difunctional unit (CH 3) 2SiO, T denotes the trifunctional unit (CH ₃ ) SiOi, ₅ and Q denotes the block or tetra unit SiO ₂ . Cousins of the unit symbols (for example, M ', D', T 'and Q'), denote substituents other than methyl and must be specifically defined for each occurrence.
[082] Silicone resins for use in the hair treatment composition may include, but are not limited to, MQ, MT, MTQ, MDT and MDTQ resins. Methyl is a possible silicone substitute. In some embodiments, silicone resins are MQ resins, in which the M: Q ratio is about 0.5: i, o to about i, 5: i, o and the average molecular weight of the silicone resin is about i.ooo about io.ooo.
[o83] The weight ratio between the non-volatile silicone fluid component, which has a refractive index below 1.46, and the silicone resin component, when used, can be about 4: ia to 4oo: i , alternatively from about 9: 1 to about 200: 1, and alternatively from about i9: ia to ioo: i, particularly when the silicone fluid component is a polydimethyl siloxane fluid or a mixture of polydimethyl siloxane fluid and polydimethyl siloxane gum as described herein. As the silicone resin forms part of the same phase in the compositions of the present invention as the silicone fluid, that is, the conditioning conditioner, the sum of fluid and resin needs to be
27/57 included in the determination of the level of conditioning agent based on silicone in the composition.
[084] b. Organic conditioning oils [085] The conditioning agent of the hair treatment composition can also comprise at least one organic conditioning oil, either alone or in combination with other conditioning agents, such as the silicones described above.

[129] (5) Cationic synthetic polymer [130] The cationic polymer described here assists in providing damaged hair, particularly chemically treated hair, with a replacement hydrophobic F-layer. Lyotropic liquid crystals are formed by combining the cationic synthetic polymers described here with the anionic detersive surfactant component mentioned above in the shampoo composition. The synthetic cationic polymer has a relatively high charge density. It should be noted that some synthetic polymers that have a relatively high cationic charge density do not form liotropic liquid crystals, mainly due to their abnormal linear charge densities. Such cationic synthetic polymers are described in WO 94/06403 issued to Reich et al.
37/57 [131] The concentration of cationic polymers is in the range of about 0.025% to about 5%, preferably from about 0.1% to about 3%, more preferably from about 0.2% to about 1% by weight of the shampoo composition.

In one embodiment, the 1-hydroxy-2pyridinothione salts in the form of platelet particles have an average particle size of up to about 20 micrometers or up to about 5 micrometers or up to about 2.5 micrometers. Salts formed from other cations, such as sodium, may also be suitable. Anti-dandruff pyridinothione actives are described, for example, in US Patent No. 2,809,971;
US patent No. 3,236,733; patent US No. 3,753. 196; patent US No. 3,761. 418; patent US No. 4,345. 080; patent US n ° 4,323,683; US patent n ° 4,379 .753; and on patent US n °
4,470,982.
[145] In one embodiment, in addition to the anti-dandruff active selected from polyvalent metal salts of pyrithione, the composition additionally comprises one or more actives
43/57 antifungals and / or antimicrobials. In one embodiment, the antimicrobial active ingredient is selected from the group consisting of: coal tar, sulfur, Whitfield's ointment, Castellani's tincture, aluminum chloride, gentian violet, octopirox (pyroctone olamine), cyclopyroxamine-olamine, undecylenic acid and its metal salts, potassium permanganate, selenium sulfide, sodium thiosulfate, propylene glycol, bitter orange oil, urea preparations, griseofulvin, 8-hydroxy-quinoline-chylquinol, thiobendazole, thiocarbamates, haloprogine, polyoxides, hydroxy-pyridone , morpholine, benzylamine, allylamines (such as terbinafine), tea tree oil, clove leaf oil, coriander, palmarosa, berberine, thymus, cinnamon oil, cinnamic aldehyde, citronellic acid, hinocytol, pale ichthiol, Sensiva SC -50, Elestab HP-100, azelaic acid, liticase, iodopropynyl butylcarbamate (IPBC), isothiazalinones such as octyl-isothiazalinone and azoles, and mixtures thereof. In one embodiment, the antimicrobial is selected from the group consisting of: itraconazole, ketoconazole, selenium sulfide, coal tar and mixtures thereof.
[146] In one embodiment, azole antimicrobials are an imidazole selected from the group consisting of: benzimidazole, benzothiazole, bifonazole, butaconazole nitrate, climbazole, clotrimazole, croconazole, eberconazole, econazole, elubiol, fenticonazole, fluczazole, fluconazole, fluczazole, fluczazole, fluczazole, fluconazole, fluconazole , ketoconazole, lanoconazole, metronidazole, miconazole, neticonazole, omoconazole, oxiconazole nitrate, sertaconazole, sulconazole nitrate, tioconazole, thiazole and mixtures thereof, or azole antimicrobials are a triazole selected from the group consisting of: terconazol mixtures thereof. When present in
44/57 composition for hair treatment, the azole antimicrobial active is included in an amount of about 0.01% by weight, to about 5% by weight, or about 0.1% by weight, about 3% by weight, or about 0.3% by weight, to about 2% by weight. In one embodiment, the azole antimicrobial asset is ketoconazole. In one embodiment, the antimicrobial active ingredient alone is ketoconazole.
[147] Modalities of the hair treatment composition may also comprise a combination of active antimicrobial agents. In one embodiment, a combination of antimicrobial actives is selected from the group of combinations consisting of: octopirox and zinc pyrithione, pine and sulfur tar, salicylic acid and zinc pyrithione, salicylic acid and elubiol, zinc pyrithione and elubiol, zinc pyrithione and climbasol , octopirox and climbasol, salicylic acid and octopirox and mixtures thereof.
[148] In one embodiment, the composition comprises an effective amount of a layered material containing zinc. In one embodiment, the composition comprises from about 0.001% by weight to about 10% by weight or from about 0.01% by weight to about 7% by weight or about 0.1% by weight, to about 5% by weight, of a layered material containing zinc, by total weight of the composition.
[149] Layered materials containing zinc may be those with crystal growth occurring mainly in two dimensions. It is conventional to describe layered structures as not only those in which all atoms are embedded in well-defined layers, but also those in which there are ions or molecules between the layers, called gallery ions
45/57 (A.F. Wells Structural Inorganic Chemistry Clarendon Press, 1975). Zinc-containing layered materials (ZLMs) may have zinc embedded in the layers and / or be components of gallery ions. The following classes of ZLMs represent relatively common examples from the general category and are not intended to limit the broader scope of materials that fit that definition.
[150] Many ZLMs occur naturally as minerals. In one embodiment, ZLM is selected from the group consisting of: hydrozincite (zinc carbonate hydroxide), auricalcite (zinc-copper carbonate hydroxide), rosesite (copper-zinc carbonate hydroxide) and mixtures thereof. Related zinc-containing minerals can also be included in the composition. Natural ZLMs can also occur as anionic layer species, such as clay-type minerals (eg, phyllosilicates) contain zinc gallery ions resulting from ion exchange. All of these natural materials can also be obtained synthetically or formed in situ in a composition or during a production process.
[151] Another common class of ZLMs that is often, but not always, synthetic is double layered hydroxides. In one embodiment, ZLM is a double layered hydroxide according to the formula [M ²⁺ i-xM ³⁺ x (OH) 2] ^{x +} A ^m _x / _m ^ nH2O in which some or all of the divalent ions ( M ²⁺ ) are zinc ions (Crepaldi, EL, Pava, PC, Tronto, J, Valim, JB J. Colloid Interfac. Sci. 2002, 248, 429 to 442).
[152] Yet another class of ZLMs can be prepared which is called double hydroxy salts (Morioka, H., Tagaya, H., Karasu, M, Kadokawa, J, Chiba, K Inorg. Chem. 1999, 38, 4211 to 416). In one embodiment, ZLM is a double salt of
46/57 hydroxy according to the formula [M ²⁺ i_xM ²⁺ i + x (OH) ₃ (i_ _y) ] ⁺ A ⁿ (i = 3y) / n * nH2O, where the two metal ions (M ^{2 +} ) can be the same or different. If they are equal and represented by zinc, the formula is simplified to [Zn1 + x (OH) ₂ ] ^{2x +} 2x A-nH ₂ O. This last formula represents (where x = 0.4) materials such as zinc hydroxychloride and hydroxynitrate of zinc. In one embodiment, the ZLM is zinc hydroxychloride and / or zinc hydroxynitrate. These are related to hydrozincite as well, with the divalent anion replacing the monovalent anion. These materials can also be formed in situ in a composition or during a production process.
[153] In embodiments that have a zinc-containing layered material and a pyrithione or a polyvalent metallic pyrithione salt, the ratio of layered material that contains zinc and pyrithione or polyvalent metallic pyrithione salt is about 5: 100 to 10: 1 or about 2:10 to about 5: 1 or about 1: 2 to about 3: 1.
[154] The deposition of anti-dandruff active on the scalp is at least about 1 microgram / cm ² . The deposition on the scalp of the anti-dandruff active is important in order to ensure that the anti-dandruff active reaches the scalp where it is able to perform its function. In one embodiment, the deposition of the anti-dandruff active on the scalp is at least about 1.5 micrograms / cm ² , or at least about 2.5 micrograms / cm ² , or at least about 3 micrograms / cm ² , or at least about 4 micrograms / cm ² , or at least about 6 micrograms / cm ² , or at least about 7 micrograms / cm ² , or at least about 8 micrograms / cm ² , or at least about 8 micrograms / cm ² , or at least about 10 micrograms / cm ² . Scalp deposition of the anti-dandruff active is measured
47/57 washing individuals' hair with a composition comprising an anti-dandruff active, for example, a composition according to the present invention, by a cosmetic expert trained in accordance with a conventional washing protocol. The hair is then parted in an area of the scalp to allow an open glass cylinder to be kept on the surface while an aliquot of an extraction solution is added and stirred before recovery and analytical determination of the content of the anti-dandruff active by conventional methodology, such as HPLC.
[155] Hair treatment composition modalities may also comprise fatty alcohol gel nets, which have been used for years in cosmetic creams and hair conditioners. These gel networks are formed by the combination of fatty alcohols and surfactants in the ratio of about 1: 1 to about 40: 1 (alternatively about 2: 1 to about 20: 1, and alternatively about 3: 1 to about 10: 1). The formation of a gel network involves heating a dispersion of the fatty alcohol in water with the surfactant to a temperature above the melting point of the fatty alcohol. During the mixing process, the fatty alcohol melts, allowing the surfactant to be partitioned into fatty alcohol droplets. The surfactant brings water into the fatty alcohol. This turns drops of isotropic fatty alcohol into drops of the liquid crystalline phase. When the mixture is cooled below the melting temperature of the chain, the liquid crystal phase is converted into a solid crystalline gel network. The gel network provides a stabilizing benefit for cosmetic creams and hair conditioners. Besides that,
48/57 it provides the benefits of conditioning sensation for hair conditioners.
[156] Thus, according to one modality, fatty alcohol is included in the fatty alcohol gel network at a content, by weight, of about 0.05%, by weight, to about 14%, by weight . For example, fatty alcohol can be present in an amount ranging from about 1% by weight to about 10% by weight, and alternatively from about 6% by weight to about 8% by weight.
[157] The liquid fatty alcohols useful here are those that have from about 10 to about 40 carbon atoms, from about 12 to about 22 carbon atoms, from about 16 to about 22 carbon atoms, about 16 to about 18 carbon atoms. These fatty alcohols can be straight or branched, and can be saturated or unsaturated. Some non-limiting examples of fatty alcohols include cetyl alcohol, stearyl alcohol, beenyl alcohol and mixtures of these substances. Mixtures of cetyl and stearyl alcohols at a ratio of about 20:80 to about 80:20 are also suitable.
[158] Preparation of the gel net: A vessel is loaded with water and the water is heated to about 74 ° C. Cetyl alcohol, stearyl alcohol, and SLES surfactant are added to the heated water. After incorporation, the resulting mixture is passed through a heat exchanger where the mixture is cooled to about 35 ° C. After cooling, the fatty alcohols and the surfactant crystallize to form a crystalline gel network. Table 1 provides the components and their respective amounts for the composition of the gel network.

[161] Test methods [162] It is understood that the test methods that are presented in the test methods section of the present application are to be used to determine the respective values of the inventors' parameters of the applicants as described and claimed in the present invention .
[163] A. Wet and dry conditioning test method [164] This test method is designed to allow a subjective assessment of the basic performance of conditioning shampoos for the effectiveness of wet and dry combing. The control treatments exemplified in Table 2 are (1) a clarifying shampoo that uses only surfactants and has no conditioning materials present, and (2) the same clarifying shampoo used in the washing process followed by the application of a conditioner for medium hair. These treatments facilitate the performance differentiation of a set of prototype conditioning shampoos. In a typical test, 3 to 5 separate formulations can be evaluated for their performance. The substrate is virgin brown hair obtainable from a variety of sources that is selected to ensure
50/57 uniformity and absence of significant superficial damage or hair damaged by low bleach bleaching.

[166] B. Treatment procedure [167] Five strands of 4 grams, length 20.3 cm (8 inches) are combined in a support of strands of hair, wet for ten seconds with handling with water at 40 ° C , medium hardness (0.15-1.7 g / L (9-10 gpg)) to ensure complete and uniform wetting. The strand is lightly drained and the product is applied evenly over the combined strands length of 2.54 cm (one inch) below the support towards the tip in a content of 0.1 gram of product per gram of dry hair ( 0.1 g / g of hair or 2 g for 20 g of hair). For
51/57 more concentrated prototypes, the use content is reduced to 0.05 g / g of hair. The combination of wicks is foamed for 30 seconds by a scrubbing motion typical of that used by consumers and rinsed with water at 40 ° C flowing at 5.7 L / min (1.5 gal / min) (with the hair being handled) for another 30 seconds to ensure completeness. This step is repeated. For the control treatment with conditioner, it is applied in the same way as the shampoo above, manipulated in the entire combination of strands and rinsed thoroughly with manipulation, again for 30 seconds. The strands are lightly drained, separated from each other, hung on shelves so that they do not come into contact, and untangled with a wide-toothed comb.
[168] C. Classification procedures [169] For wet combing evaluations using trained classifiers, the strands are separated on the shelves into five sets with one strand from each treatment included in the classification set. Only two combing classifications are performed on each strand. Classifiers are asked to compare treatments by combing with a narrow nylon tooth comb similar to those used by consumers and to assess ease / difficulty on a scale of zero to ten. Ten separate assessments are collected and the results are analyzed using the statistical analysis package to establish statistical significance. Control mapping is regularly used to ensure that low and high controls separate into their regular domains. The statistical significance of differences between treatments is determined with the use of
52/57
Statgraphics Plus 5.1. All conditioning prototypes must be more than two LSDs above the clarifying control to be seen as acceptable.
[170] For dry combing assessments, the above strands are moved to a controlled humidity and temperature room (22 ° C / 50% RH) and allowed to dry overnight. They remain separate as above and examiners are asked to assess dry conditioning performance through three assessments; ease of dry combing the middle of the lock, ease of dry combing of the tips, and tactile evaluation of the tips. The same ten-point scale is used for these comparisons. Again, only two examiners carry out an evaluation of each set of locks. Statistical analysis to separate differences is done using methods equal to the methods above.
[171] Examples [172] The following examples illustrate the present invention. The exemplified compositions can be prepared using conventional formulation and mixing techniques. It will be noted that other modifications of the composition for hair treatment within the scope of the practice of those versed in the hair treatment formulation technique can be carried out without deviating from the spirit and scope of this invention. All parts, percentages and reasons for this document are expressed in weight, unless otherwise specified. Some components can be obtained from suppliers in the form of diluted solutions. The fixed amount reflects the weight percent of the active material, unless otherwise specified.
