Abstract

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.
