Composition reductive for the treatment of materials, a subject-matter of the amphiphilic polymers of at least one unsaturated monomer has ethylenically a sulphonic group and comprising a hydrophobic part

摘要

The invention concerns a cosmetic composition for treating keratinous materials comprising in a carrier suitable for keratinous materials: (a) at least an amphiphilic polymer comprising at least an ethylenically unsaturated monomer with sulphonic group, in free form or partly or completely neutralised and further at least a hydrophobic part; (b) at least a reducing agent. The invention also concerns methods and devices for bleaching or permanent waving of keratinous fibres using said composition.
