Reduction of the autoxidation of agents for the oxidative dyeing and/or bleaching of keratin fibers

摘要

An agent for the oxidative dyeing of keratin fibers, in particular human hair, includes in a cosmetic carrier (a) at least one first alkyl glucoside of formula (I) set forth herein, in which R1 is an unbranched or branched, saturated or unsaturated C20-C28 alkyl group and n is an integer from 1 to 10, (b) at least one second alkyl glucoside of formula (II) set forth herein, in which R2 is an unbranched or branched, saturated or unsaturated C8-C18 alkyl group and m is an integer from 1 to 10, (c) at least one oxidation dye precursor of the developer type, and d) at least one oxidation dye precursor of the coupler type.

主权项

1. A ready to apply agent for the oxidative dyeing and/or lightening of keratinic fibers, including in a cosmetic carrier
(a) 0.3 to 4.5% by weight at least one first alkyl glucoside of formula (I) wherein R1 stands for an unbranched or branched, saturated or unsaturated C20-C28 alkyl group and n stands for an integer from 1 to 10, (b) 1.2 to 8.0% by weight at least one second alkyl glucoside of formula (II) wherein R2 stands for an unbranched or branched, saturated or unsaturated C8-C18 alkyl group and m stands for an integer from 1 to 10, (c) at least one oxidation dye precursor of the developer type, (d) at least one oxidation dye precursor of the coupler type, and (e) an oxidizing agent, wherein a ratio of all alkyl glucosides of formula (I) to all alkyl glucosides of formula (II) included in the ready-to-apply agent ranges between 1:2 and 1:10.
