Patent ID: 7771492

Claim:
A cosmetic composition for oxidation dyeing keratin fibers, comprising, in a dyeing medium (1) at least one oxidation dye, (2) at least one thickening polymer comprising at least one fatty chain chosen from: anionic thickening polymers comprising at least one hydrophilic unit of the olefinic unsaturated carboxylic acid type and at least one (C 10 -C 30 )alkyl ester of unsaturated carboxylic acid type; nonionic thickening polymers chosen from celluloses modified by at least one group comprising at least one fatty chain and polyether-polyurethanes comprising in their chain at least one hydrophilic polyoxyethylenated sequence and at least one hydrophobic sequence chosen from aliphatic chains, cycloaliphatic chains and aromatic chains; and cationic thickening polymers wherein the fatty chain is a quaternized cellulose derivative; and (3) at least one fatty alcohol chosen from monoglycerolated and polyglycerolated fatty alcohols.
