Patent ID: 7695526

Claim:
A composition for the oxidation dyeing of keratin fibers, comprising, in a medium suitable for dyeing, a) at least one oxidation dye; b) at least one fatty alcohol; c) at least one associative polymer chosen from non-ionic, anionic, cationic, and amphoteric associative polymers; wherein the non-ionic associative polymers are chosen from: (1) celluloses modified with groups comprising at least one fatty chain; (2) hydroxypropylguars modified with groups comprising at least one fatty chain; (3) polyurethane polyethers comprising in their chain both polyoxyethylenated hydrophilic blocks and hydrophobic blocks which are aliphatic sequences alone and/or cycloaliphatic and/or aromatic sequences; (4) copolymers of vinylpyrrolidone and of fatty-chain hydrophobic monomers; (5) copolymers of C 1 -C 6 alkyl methacrylates or acrylates and of amphiphilic monomers comprising at least one fatty chain; and (6) copolymers of hydrophilic methacrylates or acrylates and of hydrophobic monomers comprising at least one fatty chain; and d) at least one C 14 -C 30 alkyl sulphate; and wherein the ratio, by weight, of the at least one C 14 -C 30 alkyl sulphate to the at least one associative polymer ranges from 0.1:1 to 10:1.
