A cosmetic composition comprising, in a cosmetically acceptable medium, n at least one amphiphilic polymer chosen from branched block copolymers comprising n (a) at least one nonionic unit derived from at least one monomer chosen from C 1-20 alkyl (meth)acrylates, N-mono-(C 2-12 alkyl)-(meth)acrylamides and N,N-di-(C 2-12 alkyl)-(meth)acrylamides, n (b) at least one anionic unit derived from at least one monomer chosen from acrylic acid and methacrylic acid, and n (c) at least one polyfunctional unit derived from at least one monomer comprising at least two polymerizable unsaturated functional groups, n at least one cationic polymer, and n 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. |
