Use of succinimidyl ester compound for protection of color during the washing of artificially dyed keratin fibers especially human keratin fibers, preferably hair

摘要

Use of one or more succinimidyl ester compound (I) as an agent for protection of color during the washing of artificially dyed keratin fibers especially human keratin fibers, preferably hair, is claimed. Use of one or more succinimidyl ester compound of formula (I) as an agent for protection of color during the washing of artificially dyed keratin fibers especially human keratin fibers, preferably hair, is claimed. n : 1-4; R 1monovalent 1-30C aliphatic hydrocarbon or monovalent optionally substituted 6-30C aryl (when n is 1) or divalent 1-30C aliphatic hydrocarbon or divalent optionally substituted 6-30C aryl (when n is 2) or trivalent 1-30C aliphatic hydrocarbon or trivalent optionally substituted 6-30C aryl (when n is 3) or tetravalent 1-30C aliphatic hydrocarbon or tetravalent optionally substituted 6-30C aryl (when n is 4), where the aliphatic hydrocarbon optionally comprises at least one atom of O, N, S, P and Si, or at least one carbonyl group instead of carbon atoms and R1 is preferably monovalent radical (comprising 1-10C alkyl, 1-10C alkylene or 2-10C acyl), divalent radical (comprising 1-10C alkylene or 1-10C alkylenedithio-1-10C alkyl), trivalent radical (comprising tertiary amine substituted by 1-4C alkylene) or tetravalent radical (comprising tetra alkylene methane), where alkyl or alkylene are optionally substituted; and R2 : H or sulfo group (-SO 3H optionally salified). Independent claims are included for: (1) protecting the color during washing of artificially dyed keratin fibers such as human keratin fibers, preferably hair, comprising applying (I) to the fibers; (2) dyeing keratin fibers, especially human keratin fibers, particularly hair, comprising: applying a direct dye composition (A) or an oxidation composition (A) to the fibers in the presence of one or more oxidizing agents for a time sufficient to develop the color, and preceded or followed by the application of a composition (B) containing (I) in a medium; or applying a direct dye composition (A) or an oxidation composition (A) to the fibers, where the composition (A) contains (I) in a medium; and (3) a kit comprising at least one first component comprising a composition (B) comprising (I) in an aqueous medium, and at least one second component comprising a coloring composition (A) comprising at least one oxidation dye and/or or at least one direct dye, where the two components are optionally associated with a third component comprising one or more oxidizing agents.
