Decoloring composition, useful for keratinous fibers e.g. human hair, comprises an oxidant and an amphoteric polymer e.g. acrylamide-dimethyldiallylammonium chloride-acrylic acid terpolymer

摘要

Decoloring composition for keratinous fibers comprises an oxidant and an amphoteric polymer having repeating units of dialkyldiallylammonium halide monomers, vinyl carboxylic acid monomers and acrylamide monomers at 45-60 mol.%, where the molar ratio of the dialkyldiallylammonium halide monomer to the vinyl carboxylic acid monomer is = 1. An independent claim is included for a multiple compartment device comprising the compositions.
