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, andat 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.
