COSMETIC COMPOSITION CONTAINING A CATIONIC SURFACTANT, A CATIONIC POLYMER AND AN ACRYLIC SEQUENCE, BRANCHED, AMPHIPHILIC COPOLYMER AND METHOD OF TREATMENT.

摘要

The present invention therefore relates to a cosmetic composition comprising, in a cosmetically acceptable medium ,. at least one amphiphilic polymer chosen from branched block copolymers comprising (a) nonionic units 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) acrylamide, (b) anionic units derived from at least one monomer chosen from acid acrylic and methacrylic acid, and (c) polyfunctional units derived from at least one monomer comprising at least two polymerizable unsaturated functional groups, and preferably having a structure consisting of hydrophobic blocks to which are attached, via polyfunctional patterns (c), several more hydrophilic blocks ,. at least one cationic polymer, and. at least 3% by weight, based on the total weight of the composition, of at least one anionic surfactant, as well as a process for treating keratin materials using such a composition.
