COSMETIC COMPOSITION COMPRISING AT LEAST ONE ANIONIC SURFACTANT, AT LEAST ONE CATIONIC POLYMER AND AT LEAST ONE AMPHIPHILIC, BRANCHED BLOCK ACRYLIC COPOLYMER AND METHOD FOR TREATING HAIR USING SUCH A COMPOSITION.

摘要

A cosmetic composition comprising, in a cosmetically acceptable medium, at least one amphiphilic polymer chosen from branched block copolymers comprising (a) at least one nonionic unit derived from at least one monomer chosen from C1-20 alkyl (meth)acrylates, N-mono-(C2-12 alkyl)-(meth)acrylamides and N,N-di-(C2-12 alkyl)-(meth)acrylamides, (b) at least one anionic unit derived from at least one monomer chosen from acrylic acid and methacrylic acid, and (c) at least one polyfunctional unit derived from at least one monomer comprising at least two polymerizable unsaturated functional groups, at least one cationic polymer, and at least 3% by weight, relative to the total weight of the composition, of at least one anionic surfactant, and a method for treating a keratinous material using the composition.
