Gentle hair color pretreatment with silicone and oily oxidants

摘要

Methods and compounds are provided for oxidative coloring of keratinic fibers, in particular hair. The method includes applying a pretreatment agent onto the hair, where the pretreatment agent includes at least one 4-morpholinomethyl-substituted silicone. A hair coloring agent is applied to the hair subsequent to the pretreatment agent within a time span from about 1 second to about 24 hours. The hair coloring agent is obtained by mixing a composition (A), which contains at least one oxidation dye precursor of the developer type and at least one oxidation dye precursor of the coupler type, with a composition (B) that contains at least one oxidizing agent. Composition (B) contains at least one cosmetic oil in a total quantity from 10 to 80 wt %, based on the weight of composition (B).

主权项

1. A method for oxidative coloring of keratinic fibers, in particular of hair, the method comprising the steps of:
applying a pretreatment agent onto the keratinic fibers, in particular onto the hair, wherein the pretreatment agent contains;
at least one 4-morpholinomethyl-substituted silicone of formula (V), in whichA denotes a structural unit (I), (II), or (III) bound via —O  or an oligomeric or polymeric residue bound via —O-containing structural units of formulas (I), (II), or (III), or half of an oxygen atom connecting to a structural unit (III), or denotes —OH, denotes a bond to one of the structural units (I), (II), or (III), or denotes a terminal group B (Si-bound) or D (O-bound),B denotes an —OH, —O—Si(CH3)3, —O—Si(CH3)2OH, —O—Si(CH3)2OCH3 group,D denotes an —H, —Si(CH3)3, —Si(CH3)2OH, —Si(CH3)2OCH3 group,a, b, and c denote integers from 0 to 990, with the provision that a+b+c>0,m, n, and o denote integers from 1 to 990, applying a hair coloring agent onto the keratinic fibers subsequent to the pretreatment agent, and within a time span from about one second to about 24 hours after applying the pretreatment agent, wherein the hair coloring agent is obtained by mixing a composition (A), which contains at least one oxidation dye precursor of the developer type and at least one oxidation dye precursor of the coupler type, with a composition (B) that contains at least one oxidizing agent, and wherein composition (B) contains at least one cosmetic oil in a total quantity from about 10 to about 80 wt %, based on the weight of composition (B).
