[0025] As a result of intensive research, the inventors have discovered that it is possible to provide a composition that contains a polyion complex and that can provide improved texture, such as smoothness, softness, and less stickiness, to keratinous fibers such as hair.

[0026] Therefore, the composition according to the present invention (a) at least one ionic polymer selected from the group consisting of cationic polymers, anionic polymers, amphoteric polymers, and mixtures thereof; and At least one crosslinking agent selected from the group consisting of a non-polymeric acid or a salt thereof having two or more pKa values, a non-polymeric base or a salt thereof having two or more pKb values, and a mixture thereof. At least one polyion complex comprising (b) at least one texturing agent; and (c) Water and Includes.

[0027] (a) It may be preferable that the polyion complex is in the form of particles.

[0028] The compositions according to the present invention can provide keratinous fibers, such as hair, with improved texture, such as smoothness, softness and less stickiness.

[0029] In addition, the composition according to the present invention is stable in that it does not undergo any phase separation over time.

[0030] The composition and the like according to the present invention will be described in more detail below.

[0031] [Polyion complex] The composition according to the present invention contains at least one type of (a) polyion complex. Two or more different types of (a) polyion complexes may be used in combination. Therefore, a single type of (a) polyion complex or a combination of different types of (a) polyion complexes may be used.

[0032] (a) It may be preferable that the polyion complex is in the form of particles. The particle size of the polyion complex particles may be 5 nm to 100 μm, preferably 100 nm to 50 μm, more preferably 200 nm to 40 μm, and even more preferably 500 nm to 30 μm. Particle sizes less than 1 μm can be measured by dynamic light scattering, and particle sizes greater than 1 μm can be measured by optical microscopy. This particle size can be based on the number average diameter.

[0033] The amount of (a) polyion complex in the composition according to the present invention may be 0.01% by mass or more, preferably 0.1% by mass or more, more preferably 1% by mass or more, based on the total mass of the composition.

[0034] The amount of (a) polyion complex in the composition according to the present invention may be 25% by mass or less, preferably 20% by mass or less, more preferably 15% by mass or less, based on the total mass of the composition.

[0035] The amount of the (a) polyion complex in the composition according to the present invention may be 0.01% by mass to 25% by mass, preferably 0.1% by mass to 20% by mass, and more preferably 1% by mass to 15% by mass, relative to the total mass of the composition.

[0036] The cation / anion ratio, as the charge density of the (a) polyion complex in the composition according to the present invention, may be 1.01 to 5, preferably 1.05 to 4, more preferably 1.1 to 3, and even more preferably 1.5 to 2, expressed as the ratio of cation equivalents / g divided by anion equivalents / g.

[0037] When the composition according to the present invention contains at least one fatty substance (d), the particulate (a) polyion complex can exist at the interface between (c) water and (d) fatty substance. Therefore, the (a) polyion complex can form an emulsion, for example. For example, when (c) water constitutes the continuous phase and a fatty substance such as (d) oil constitutes the dispersed phase, the (a) polyion complex can form an O / W emulsion that may resemble a so-called Pickering emulsion.

[0038] Alternatively, the (a) polyion complex can form a capsule having a hollow space. The (d) fatty substance can be present within the hollow space. In other words, the (d) fatty substance can be incorporated into the capsule. The capsule wall can be composed of a continuous layer or film formed from the (a) polyion complex. Without wishing to be bound by theory, it is believed that the (a) polyion complex can reorganize at the interface between the (d) fatty substance and (c) water to spontaneously form a capsule having a hollow space for containing the (d) fatty substance. For example, a continuous phase composed of (c) water and a dispersed phase composed of a fatty substance such as (d) oil within a capsule can form an O / W emulsion, which can be similar to a Pickering emulsion.

[0039] The above may mean that (a) the polyion complex itself is amphiphilic and insoluble in fatty substances such as oils or in water.

[0040] {Ionic polymer and crosslinking agent} (a) Polyion complex at least one ionic polymer selected from the group consisting of cationic polymers, anionic polymers, amphoteric polymers, and mixtures thereof; and At least one crosslinking agent selected from the group consisting of a non-polymeric acid or a salt thereof having two or more pKa values, a non-polymeric base or a salt thereof having two or more pKb values, and a mixture thereof.

Therefore, a single type of anionic polymer or a combination of different types of anionic polymers may be used. Two or more different types of amphoteric polymers may be used in combination.

When the anionic polymer is a synthetic anionic polymer, the charge density of the anionic polymer may be 0.1 meq / g to 20 meq / g, preferably 1 to 15 meq / g, and more preferably 4 to 10 meq / g. When the anionic polymer is a natural anionic polymer, the average degree of substitution of the anionic polymer may be 0.1 to 3.0, preferably 0.2 to 2.7, and more preferably 0.3 to 2.5.

[0102] It may be preferred that the molecular weight of the anionic polymer is 1,000 or greater, preferably 10,000 or greater, more preferably 50,000 or greater, and even more preferably 100,000 or greater.

[0103] The anionic polymer may have at least one negatively charged moiety selected from the group consisting of sulfate groups, sulfate groups, sulfonic acid groups, sulfonate groups, phosphoric acid groups, phosphate groups, phosphonic acid groups, phosphonate groups, carboxylic acid groups, and carboxylate groups.

[0104] The anionic polymer may be a homopolymer or a copolymer. The term "copolymer" is understood to mean both copolymers obtained from two types of monomers and copolymers obtained from more than two types of monomers, for example terpolymers obtained from three types of monomers.

[0105] The anionic polymer may be selected from natural anionic polymers and synthetic anionic polymers.

[0106] The anionic polymer may comprise at least one hydrophobic chain.

[0107] The anionic polymer, which may contain at least one hydrophobic chain, can be obtained by copolymerization of a monomer (a) selected from a carboxylic acid containing α,β-ethylenic unsaturation (monomer a') and 2-acrylamido-2-methylpropanesulfonic acid (monomer a") with a non-surface-active monomer containing ethylenic unsaturation other than (a) (b) and / or a monomer (c) containing ethylenic unsaturation obtained by reacting an acrylic monomer containing α,β-monoethylenic unsaturation or an isocyanate monomer containing monoethylenic unsaturation with a monovalent nonionic amphiphilic component or a primary or secondary fatty amine.

[0108] Therefore, anionic polymers with at least one hydrophobic chain can be synthesized via two synthetic routes: by copolymerization of the monomers (a') and (c), or (a'), (b) and (c), or (a") and (c), or (a"), (b) and (c), or by modifying (in particular by esterification or amidation) the monomer (a'), or a copolymer formed from the monomers (a') and (b), or (a") and (b), with a monovalent nonionic amphiphilic compound or a primary or secondary aliphatic amine; It can be obtained by either

[0110] The carboxylic acid containing α,β-monoethylenic unsaturation constituting the monomer (a′) can be chosen from a large number of acids, in particular from acrylic acid, methacrylic acid, crotonic acid, itaconic acid and maleic acid, and is preferably acrylic acid or methacrylic acid.

[0111] The copolymer may contain a monomer (b) containing monoethylenic unsaturation without surfactant properties. Preferred monomers are those which, when homopolymerized, give water-insoluble polymers. These can be selected, for example, from C1-C4 alkyl acrylates and methacrylates, such as methyl acrylate, ethyl acrylate, butyl acrylate, or the corresponding methacrylates. More particularly preferred monomers are methyl acrylate and ethyl acrylate. Other monomers that can be used are, for example, styrene, vinyl toluene, vinyl acetate, acrylonitrile, and vinylidene chloride. Nonreactive monomers are preferred; these are those in which a single ethylenic group is the only group reactive under the polymerization conditions. However, monomers containing groups that react under the action of heat, such as hydroxyethyl acrylate, can optionally be used.

[0112] Monomer (c) is obtained by reacting an acrylic monomer containing α,β-monoethylenic unsaturation, such as (a), or an isocyanate monomer containing monoethylenic unsaturation, with a monovalent nonionic amphiphilic compound or a primary or secondary aliphatic amine.

[0113] The monovalent nonionic amphiphilic compounds or primary or secondary aliphatic amines used to produce the nonionic monomer (c) are well known. The monovalent nonionic amphiphilic compounds are generally alkoxylated hydrophobic compounds containing alkylene oxides that form the hydrophilic portion of the molecule. The hydrophobic compounds are generally composed of aliphatic alcohols or alkylphenols, in which a carbonaceous chain containing at least 6 carbon atoms constitutes the hydrophobic portion of the amphiphilic compound.

[0114] Preferred monovalent nonionic amphiphilic compounds have the formula (V): R-(OCH2CHR') m -(OCH2CH2) n -OH (V) wherein R is selected from alkyl or alkylene groups containing 6 to 30 carbon atoms and alkylaryl groups having an alkyl group containing 8 to 30 carbon atoms; R' is selected from alkyl groups containing 1 to 4 carbon atoms; n is an average number ranging from approximately 1 to 150; and m is an average number ranging from approximately 0 to 50, with the proviso that n is at least equal to m. It is a compound having the formula:

[0115] Preferably, in the compounds of formula (V), the R group is an alkyl group containing 12 to 26 carbon atoms, and the alkyl group is a C8 to C 13 wherein R′ is a methyl group, m=0, and n=1-25.

[0116] Preferred primary and secondary fatty amines are composed of one or two alkyl chains containing from 6 to 30 carbon atoms.

[0117] The monomers used to form the nonionic urethane monomer (c) can be selected from a wide variety of compounds. Any compound containing copolymerizable unsaturation, such as acrylic, methacrylic, or allylic unsaturation, can be used. Monomer (c) can be derived, in particular, from isocyanates containing monoethylenic unsaturation, such as, in particular, α,α-dimethyl-m-isopropenylbenzyl isocyanate.

[0119] According to a particular embodiment of the present invention, the anionic polymer is selected from an acrylic terpolymer obtained from (a) a carboxylic acid containing α,β-ethylenic unsaturation, (b) a non-surface-active monomer containing ethylenic unsaturation other than (a), and (c) a nonionic urethane monomer which is the reaction product of a monovalent nonionic amphiphilic compound with an isocyanate containing monoethylenic unsaturation.

[0213] (b) The texturing agent is preferably selected from hydrophilic non-ionic polymeric thickeners, which herein means hydrophilic non-ionic thickeners based on at least one polymer.

[0214] It is more preferred that the (b) texturing agent is selected from hydrophilic non-ionic polymeric associative thickeners and hydrophilic non-ionic polysaccharide thickeners.

[0215] Since thickeners are generally thought to provide more stickiness, it is surprising that (b) texturizing agents that can function as thickeners can also provide better texture, such as more smoothness and less stickiness, to keratin fibers such as hair.

[0216] {Hydrophilic nonionic polymeric associative thickener} A hydrophilic nonionic polymeric associative thickener, as used herein, is a thickener that contains at least one hydrophilic unit and at least one hydrophobic unit, such as at least one C-C 30 By "thickener" is meant a non-ionic thickener comprising at least one polymer having both a fatty chain and a non-ionic surfactant, and which is hydrophilic overall so that it can thicken an aqueous phase.

[0217] The hydrophilic non-ionic polymeric associative thickener can be chosen, for example, from: (i) cellulose modified with a group containing at least one fatty chain, examples which may be mentioned are: - Hydroxyethylcellulose modified with at least one fatty chain-containing group selected from alkyl, arylalkyl and alkylaryl groups, wherein the alkyl group is, for example, C8 to C 22Hydroxyethylcellulose, such as the product Natrosol Plus Grade 330 CS (C1-C6 alkyl) sold by the company Aqualon, and the product Bermocoll EHM 100 sold by Berol Nobel, cellulose modified with polyalkylene glycol alkylphenyl ether groups, such as the product Amercell Polymer HM-1500 sold by the company Amerchol [polyethylene glycol (15) nonylphenyl ether]; (ii) hydroxypropyl guar modified with a group containing at least one fatty chain, such as the product Esaflor HM 22 (C) sold by the company Lamberti 22 alkyl chain), and the product Miracare XC95-3 (C 14 alkyl chain) and RE205-1(C 20 alkyl chain), (iii) at least one fatty chain, e.g., C 10 ~C 30 polyetherurethanes containing alkyl or alkenyl groups, such as the products Elfacos T 210 and Elfacos T 212 sold by the company Akzo or the products Aculyn 44 and Aculyn 46 sold by the company Rohm & Haas; (iv) copolymers of vinylpyrrolidone and hydrophobic fatty chain monomers, examples which may be mentioned are: - the products Antaron V216 and Ganex V216 (vinylpyrrolidone / hexadecene copolymer) sold by the company ISP, and - Products Antaron V220 and Ganex V220 (vinylpyrrolidone / eicosene copolymer) sold by ISP copolymers of C1-C6 alkyl acrylates or C1-C6 alkyl methacrylates with amphoteric monomers containing at least one fatty chain, such as the oxyethylenated methyl methacrylate / stearyl acrylate copolymer sold under the name Antil 208 by the company Goldschmidt; (vi) Copolymers of hydrophilic acrylates or methacrylates with hydrophobic monomers containing at least one fatty chain, such as polyethylene glycol methacrylate / lauryl methacrylate copolymer.

[0218] It may be preferable that the hydrophilic nonionic polymeric associative thickener is selected from polyether-polyurethanes. Polyether-polyurethanes may have both at least one hydrophilic moiety and at least one hydrophobic moiety. More particularly, they may contain in their polymer chains both hydrophilic sequences, often polyoxyethylenic, and hydrophobic sequences, which may be solely aliphatic and / or alicyclic and / or aromatic.

[0219] Preferably, these polyether-polyurethanes contain at least two lipophilic hydrocarbon chains having 6 to 30, preferably 6 to 20, carbon atoms, separated by a hydrophilic sequence, which hydrocarbon chains can be pendant chains or chains at the ends of the hydrophilic sequence. In particular, one or more pendant chains can be envisaged. In addition, the polyether-polyurethanes can contain hydrocarbon chains at one or both ends of the hydrophilic sequence.

[0220] Polyether-polyurethanes may contain polyblocks, particularly triblocks. The hydrophobic sequences may be at each end of the polymer chain (e.g., triblock copolymers with a hydrophilic central sequence), or may be distributed at both ends and throughout the polymer chain (e.g., polyblock copolymers). The same polymer may also be in the form of grafted units or in a star configuration.

[0221] Hydrophilic nonionic polymeric associative thickeners are capable of forming networks in water in which the hydrophobic moieties can combine to form quasi-micelles.

[0222] Thus, the hydrophilic nonionic polymeric associative thickener can increase the viscosity or consistency of the composition according to the invention, so that after application of the composition according to the invention, it can quickly restore the original elasticity of the composition.

[0223] The non-ionic polyether-polyurethane containing fatty chains may be a triblock copolymer whose hydrophilic sequence is a polyoxyethylenated chain containing from 50 to 1000 oxyethylenated groups.

[0224] Nonionic polyether-polyurethanes contain urethane linkages between hydrophilic sequences, hence the name.

[0225] By extension, non-ionic polyether-polyurethanes containing hydrophobic chains also include those whose hydrophilic sequences are linked to hydrophobic sequences by other chemical bonds.

[0226] As an example of a non-ionic polyether-polyurethane containing hydrophobic chains that can be used in the present invention, it is also possible to use Rheolate® 205, which contains urea functional groups and is sold by the company RHEOX, or else Rheolate® 208, 204 or 212, and Acrysol RM 184®.

[0229] It is also possible to use solutions or dispersions of these polymers, in particular in water or in aqueous-alcoholic media. Examples of such polymers include Rheolate® 255, Rheolate® 278 and Rheolate® 244 sold by the company RHEOX. It is also possible to use the products DW 1206F and DW 1206J offered by the company ROHM & HAAS.

[0230] The polyether-polyurethanes that can be used can also be chosen from those described in the article by G. Fonnum, J. Bakke and Fk. Hansen, Colloid Polym. Sci 271, 380-389 (1993).

[0231] The polyether-polyurethane may be a polyether-polyurethane containing, in its chain, at least one polyoxyethylenated hydrophilic block and at least one hydrophobic block containing at least one sequence selected from an aliphatic sequence, an alicyclic sequence, and an aromatic sequence.

[0232] It may be preferred that the polyether-polyurethane comprises at least two hydrocarbon chains having 8 to 30 carbon atoms, separated by a hydrophilic block, chosen from pendant chains and chains at the end of the hydrophilic block.

[0244] Also, R 2 is determined by the alkylene oxide, styrene oxide, etc. to be added. In particular, alkylene oxides having 2 to 4 carbon atoms or styrene oxide are preferred because of their availability and excellent effects.

[0245] The alkylene oxide, styrene oxide, etc. to be added may be homopolymerized, or may be randomly or block polymerized with at least two members. The procedure for addition may be a conventional procedure. The degree of polymerization k may be selected within the range of 0 to 1,000, preferably within the range of 1 to 500, and more preferably within the range of 10 to 200.

[0247] formula R 3 -(NCO) h+1 The polyisocyanate that can be preferably used to obtain the hydrophobically modified polyether urethane represented by general formula (1) used in the present invention is not particularly limited, as long as the polyisocyanate has at least two isocyanate groups in the molecule. Examples of polyisocyanates include aliphatic diisocyanates, aromatic diisocyanates, alicyclic diisocyanates, biphenyl diisocyanate, phenylmethane diisocyanate, phenylmethane triisocyanate, and phenylmethane tetraisocyanate.

[0249] Furthermore, it is possible to use a polyisocyanate having a urethane bond obtained by the reaction of the above-mentioned polyisocyanate compound with a polyol. As the polyol, a dihydric to octahydric polyol is preferred, and the polyols listed above are preferred. The trihydric or higher polyisocyanate is a polyisocyanate represented by the formula R 3 -(NCO) n+1 In the case where the polyisocyanate represented by the formula (I) is used, it is preferable to use the aforementioned polyisocyanates having a urethane bond.

[0250] Formula HO-(R 4 -O) n -R 5 The polyether monoalcohol that can be preferably used to obtain the hydrophobically modified polyether urethane represented by general formula (1) used in the present invention is not particularly limited, as long as the polyether monoalcohol is a polyether of a linear, branched, or secondary monohydric alcohol. The polyether monoalcohol can be obtained by addition polymerization of a linear, branched, or secondary monohydric alcohol with an alkylene oxide, such as ethylene oxide, propylene oxide, butylene oxide, epichlorohydrin, or styrene oxide.

[0251] The compound represented by general formula (1) is produced, for example, by heating at a temperature of 80 to 90°C for 1 to 3 hours, thereby inducing a reaction in the same manner as in the usual reaction of polyether and isocyanate.

[0252] The compound represented by general formula (1) is preferably polyethylene glycol-240 / decyltetradeceth-20 / hexamethylene diisocyanate copolymer, which is also called PEG-240 / HDI copolymer bis-decyltetradeceth-20 ether.

[0253] According to the invention, it is preferred that the hydrophilic nonionic polymeric associative thickener is chosen from the steareth-100 / PEG-136 / HDI copolymer sold under the name Rheolate FX 1100 by the company Rheox, the PEG-240 / HDI copolymer bis-decyltetradeceth-20 ether sold under the name Adekanol GT-700 by Asahi Denka Kogyo Co., Ltd., and mixtures thereof.

[0254] {Hydrophilic nonionic polysaccharide thickener} By hydrophilic non-ionic polysaccharide thickener is meant herein a hydrophilic non-ionic thickener which is preferably based on at least one polysaccharide as the backbone of the thickener.

[0255] The hydrophilic nonionic polysaccharide thickeners may be selected from those described, for example, in "Encyclopedia of Chemical Technology," Kirk-Othmer, 3rd Edition, 1982, Vol. 3, pp. 896-900, and Vol. 15, pp. 439-458; in "Polymers in Nature," E.A. MacGregor and C.T. Greenwood, published by John Wiley & Sons, Inc., Chapter 6, pp. 240-328, 1980; and in "Industrial Gums—Polysaccharides and Their Derivatives," edited by Roy L. Whistler, 2nd Edition, published by Academic Press Inc., the contents of which three publications are incorporated by reference in their entirety.

[0256] In particular, hydrophilic nonionic polysaccharide thickeners include, for example, glucans, modified and unmodified starches (e.g., those derived from cereals, such as wheat, corn or rice, those derived from vegetables, such as yellow pea, and tubers, such as potato or cassava), amylose, amylopectin, glycogen, dextran, cellulose and derivatives thereof (methylcellulose, hydroxyalkylcellulose, ethylhydroxyethylcellulose and carboxymethylcellulose), mannans, xylans, lignins. , araban, galactan, galacturonan, chitin, chitosan, glucuronoxylan, arabinoxylan, xyloglucan, glucomannan, pectic acid and pectin, alginic acid and alginates, arabinogalactan, carrageenan, agar, glycosaminoglucan, gum arabic, gum tragacanth, gum ghatti, gum karaya, carob gum, galactomannans such as guar gum and non-ionic derivatives thereof (e.g. hydroxypropyl guar), and xanthan gum, and mixtures thereof.

[0257] As hydrophilic non-ionic polysaccharide thickeners, for example starch, guar gum and cellulose, and derivatives thereof, can preferably be used.

[0258] Among the starches that can be used, mention can be made, for example, of macromolecules in the form of polymers containing elementary moieties that are anhydroglucose units. The number of these moieties and their assembly make it possible to distinguish between amylose (linear polymers) and amylopectin (branched polymers). The relative proportions of amylose and amylopectin, as well as their degree of polymerization, can vary as a function of the plant origin of the starch.

[0259] The plant origin of the starch molecules may be a cereal or tuber, and thus the starch may be chosen from, for example, corn starch, rice starch, cassava starch, tapioca starch, barley starch, potato starch, wheat starch, sorghum starch and pea starch.

[0260] Starch is generally in the form of a white powder that is insoluble in cold water and has an elementary particle size ranging from 3 to 100 microns.

[0261] The starch may optionally be C1-C6 hydroxyalkylated or C1-C6 acylated (e.g., acetylated). The starch may also be subjected to a heat treatment.

[0262] Distarch phosphate or compounds rich in distarch phosphate can also be used, such as the products sold by the company Avebe under the references Prejel VA-70-T AGGL (gelatinized hydroxypropylated cassava distarch phosphate), or Prejel TK1 (gelatinized cassava distarch phosphate), or Prejel 200 (gelatinized acetylated cassava distarch phosphate), or Structure Zea (hydroxypropylated corn distarch phosphate) from National Starch.

[0263] The guar gum may be modified or unmodified.

[0264] Unmodified guar gums are, for example, the products sold under the names Vidogum GH 175 by the company Unipectine and Meypro-Guar 50 and Jaguar C by the company Meyhall.

[0265] The modified nonionic guar gum is, for example, modified with a C1 to C6 hydroxyalkyl group.

[0266] Among the hydroxyalkyl groups, mention may be made, for example, of the hydroxymethyl, hydroxyethyl, hydroxypropyl and hydroxybutyl groups. These guar gums are well known in the prior art and can be prepared, for example, by reacting guar gum with the corresponding alkene oxide, such as propylene oxide, to obtain guar gum modified with hydroxypropyl groups.

[0267] The degree of hydroxyalkylation corresponds to the number of alkylene oxide molecules consumed by the number of free hydroxy functional groups present in the guar gum and can range, for example, from 0.4 to 1.2.

[0268] Such non-ionic guar gums, optionally modified with hydroxyalkyl groups, are sold, for example, by the company Solvay under the trade names Jaguar HP-8, Jaguar HP-60 and Jaguar HP-120.

[0269] Among the celluloses used are, for example, hydroxyethyl cellulose and hydroxypropyl cellulose. Mention may be made of the products sold by the company Ashland under the names Klucel EF, Klucel H, Klucel MF and Klucel G.

[0270] Alternatively, polysaccharides derived from microorganisms may also be preferably used as hydrophilic nonionic polysaccharide thickeners.

[0271] Microbial polysaccharides refer to polysaccharides produced by microorganisms such as germs or bacteria.

[0272] Microbial-derived polysaccharides are not plant-derived polysaccharides, and therefore it may be preferred that the microbial-derived polysaccharide is not cellulose-based.

[0273] Examples of polysaccharides derived from microorganisms include cardulan, xanthan gum, gellan gum, dextran, pullulan, sclerotium gum, and mixtures thereof.

[0274] It may be preferred that the microbially derived polysaccharide is selected from the group consisting of sclerotium gum, xanthan gum, and mixtures thereof.

[0275] (b) It may be even more preferred that the texturing agent is selected from the group consisting of agar, guar gum, hydroxyl propyl guar gum, sclerotium gum, and PEG-240 / HDI copolymer bis-decyltetradecas-20 ether.
