Oxidizing compositions containing a mixture of polymers including at least one copolymer based on acrylamide and 2-acrylamido-2-methylpropanesulphonic acid

Abstract

The invention relates to an oxidizing composition for keratin fibers, in particular for human keratin fibers and more particularly the hair, comprising, in a cosmetically acceptable medium: at least one oxidizing agent chosen from the group formed by hydrogen peroxide and compounds capable of producing hydrogen peroxide by hydrolysis, or mixtures thereof, at least one copolymer (b) based on 2-acrylamido-2-methylpropanesulphonic acid and acrylamide, and at least one polymer (c) chosen from crosslinked 2-acrylamido-2-methylpropanesulphonic acid homopolymers or amphiphilic copolymers consisting of at least one sequence of 2-acrylamido-2-methylpropanesulphonic acid units and at least one unit comprising a hydrophobic portion. The invention also relates to the dyeing, permanent-waving, bleaching and stripping processes and devices using the said composition.
