20 5 COMPOSITION FOR THE OXIDATION DYEING OF KERATINOUS FIBRES COMPRISING A FATTY ALCOHOL HAVING MORE THAN TWENTY CARBON ATOMS AND AN OXYALKYLENATED NONIONIC SURFACTANT WITH AN HLB GREATER THAN 5

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 composition for oxidation dyeing keratin fibers, such as human keratin fibers like hair, comprises, in a dyeing medium, (1) at least one oxidation dye, (2) at least one fatty alcohol comprising more than twenty carbon atoms, (3) optionally at least one fatty alcohol having at most twenty carbon atoms, (4) at least one oxyalkylenated nonionic surfactant with an HLB greater than 5, and (5) optionally at least one oxyalkylenated surfactant with an HLB at most equal to 5, in a proportion such that the weight ratio £(4)|/£(2)+(3)+(5)| is less than or equal to 1:1.
