Abstract

Oxidative dyeing of human hair upon the basis of a carrier and a dye mixture dissolved therein, whereby the carrier is made from PA1 (1) 16 to 30% by weight of a mixture of PA2 (a) 0.2-5.0% by weight of at least one physiologically harmless water soluble inorganic salt, PA2 (b) 1.4-5.0% by weight sodium lauryl alcohol diglycol ether sulfate, PA2 (c) 0.5-6.0% by weight coconut oil acid diethanol amide, PA2 (d) 4.0-10.0% by weight of a mixture consisting of PA3 60 to 80 parts by weight cetyl stearyl alcohol PA3 10 to 30 parts by weight glycerin-mono-di-stearate and PA3 0 to 20 parts by weight wool wax alcohol as well as PA2 (e) 0.1-2.0% by weight quaternized homopolymerisate of dimethyl amino ethyl methacrylate, PA1 (2) 56 to 83% by weight of water, PA1 (3) 0.1 to 5.0% by weight ammonia, PA1 (4) 0 to 5% by weight aliphatic alcohol, PA1 (5) 0 to 1% by weight perfume oil and PA1 (6) 0 to 0.5% by weight of a complex former for heavy metals The oxidative hair dyeing composition has a relatively low viscosity, is quickly miscible with the hydrogen peroxide solution and can be easily distributed in the hair. It acts untangling and smoothing on the hair and can be easily and completely rins…
