Abstract

Composition for dyeing or bleaching hair, to be mixed with an oxidizing solution at the time of use and containing: PA1 (a) a fatty acid soap, PA1 (b) a cationic or amphoteric silicone polymer, PA1 (c) a cationic surface agent, PA1 (d) an alkalifying agent, and PA1 (e) a cationic polymer chosen from quaternary polyammonium polymers, quaternized or unquaternized vinylpyrrolidone/dialkylaminoalkyl acrylate or methacrylate copolymers, poly(methacrylamidopropyltrimethylammonium chloride), cationic proteins and polyaminoamides which may crosslinked or alkylated. When these compositions are intended for dyeing hair, they also contain oxidation dye precursors and, if desired, couplers, as well as a reducing agent. This composition, which foams slightly, allows a very easy distribution throughout the hair and it improves the cosmetic properties of the hair, especially its disentangling, and imparts a silky feel thereto.
