20 COMPOSITION FOR THE OXIDATION DYEING OF KERATINOUS FIBRES COMPRISING A THICKENING POLYMER COMPRISING AT LEAST ONE FATTY CHAIN AND A FATTY ALCOHOL HANG MORE THAN TWENTY ATOMS

摘要

PURPOSE: Provided are ready-to-use oxidation dyeing compositions that resist running and tend to remain well-confined to the site of application. Additionally, such compositions may favor more intense and more chromatic (radiant) shades, while exhibiting low selectivities and good fastness toward chemical agents (shampoo, permanent waving and the like) and/or natural agents (light, perspiration and the like), and while offering the hair good cosmetic properties. CONSTITUTION: The 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, and (3) at least one fatty alcohol comprising more than twenty carbon atoms. Where, the keratin fibers are chosen from human keratin fibers chosen from human hair; and the at least one fatty alcohol comprising more than twenty carbon atoms is chosen from behenyl alcohol and erucyl alcohol and is a mixture of fatty alcohols comprising at least 30% by weight of at least one fatty alcohol comprising more than twenty carbon atoms.
