Abstract: The agent for coloring keratin fibers is free of chemical oxidants, is in the form of an aqueous or aqueous-alcoholic dye-containing preparation, and contains a combination of oxidation dyes and at least three direct dyes. The agent is characterized by a quantitative ratio of oxidation dyes to direct dyes equal to 5:1 to 0.5:1. A method of dyeing hair is described in which the agent is applied to hair and allowed to act on the hair for an acting time of 5 to 60 minutes without addition of chemical oxidants, so that air oxidation provides a uniform and stable coloration of the hair.

Abstract: The invention relates to compositions for the oxidative or non-oxidative dyeing of keratin fibers, compositions for the simultaneously lightening and coloring of keratin fibers or compositions for the bleaching of keratin fibers, comprising an anionic acrylic thickener obtained by polymerization of (i) 5 to 95 molar percent of at least one monomer performing a weak acid function, and of (ii) 5 to 95 molar percent of at least one monomer performing a strong acid function, wherein such composition exhibits a fraction of water-soluble polymers ranging from 5 to 50 percent by weight of the total polymer, as well as the use of the above anionic acrylic thickener to thicken compositions for the oxidative or non-oxidative dyeing of keratin fibers, compositions for the simultaneously lightening and coloring of keratin fibers or compositions for the bleaching of keratin fibers.

Abstract: The dye carrier composition containing oxidative and/or nonoxidative dyes has a nacreous luster because it contains a combination of (a) 6.1 to 20 weight percent of at least one fatty alcohol with 14 to 20 carbon atoms, (b) 6.1 to 20 weight percent of at least one alkanolamide, (c) 0.1 to 15 weight percent of at least one fatty alcohol alkoxylate or fatty acid alkoxylate and (d) 0.1 to 15 weight percent of at least one anionic surfactant, wherein the weight ratio of fatty alcohol (a) to alkanolamide (b) is equal to 0.5:2 to 2:0.5, preferably from 0.8:1.2 to 1.2:0.8. The weight ratio of alkoxylate to anionic surfactant is preferably from 0.5:2 to 2:0.5.
