Patent ID: 7176170

Claim:
A composition for washing keratinous substances, comprising, in a cosmetically acceptable aqueous or aqueous/alcoholic medium, at least one anionic or nonionic, amphiphilic linear block copolymer comprising at least one hydrophobic block and at least one hydrophilic block, with the exception of block copolymers of ethylene oxide and of propylene oxide, block copolymers comprising urethane units and block copolymers comprising siloxane units, at least one silicone which is nonvolatile at ambient temperature, and at least one anionic surface-active agent in combination with at least one nonionic surface-active agent and/or at least one amphoteric surface-active agent, wherein the hydrophilic block of the amphiphilic linear block copolymer are formed of water-soluble monomers chosen from anionic water-soluble monomers, nonionic water-soluble monomers or a mixture of these, said anionic water-soluble monomers being selected from carboxylic acids comprising ethylenic unsaturation, 2-acrylamido-2-methylpropanesulphonic acid, styrenesulphonic acid, vinylsulphonic acid and vinylphosphonic acid, said nonionic water-soluble monomers being selected from acrylamide, N-(C 1-6 alkylated)acrylamides or N,N-di(C 1-3 alkylated)acrylamides, polyethylene glycol acrylate, polyethylene glycol methacrylate, N-vinylacetamide, N-methyl-N-vinylacetamide, N-vinylformamide, N-methyl-N-vinylformamide, N-vinyllactams comprising a cyclic group of 4 to 9 carbon atoms, vinyl alcohol, ethylene oxide, hydroxyethyl acrylate, hydroxypropyl acrylate, hydroxyethyl methacrylate and hydroxypropyl methacrylate, and said hydroohobic block being formed of water-insoluble monomers chosen from vinylaromatic monomers, dienes and alkylated derivatives of dienes, chloroprene, C 1-10 alkyl, C 6-10 aryl or C 1-10 aralkyl acrylates, C 1-10 alkyl, C 6-10 aryl or C 1-10 aralkyl methacrylates, vinyl acetate, vinyl ethers of formula CH 2 ═CH—O—R and allyl ethers of formula CH 2 ═CH—CH 2 —O—R where R represents a C 1-6 alkyl group, acrylonitrile, vinyl chloride, vinylidene chloride, caprolactone, ethylene, propylene and fluorinated vinyl monomers or vinyl monomers comprising a perfluorinated chain.
