ABSTRACT OF THE DISCLOSURE Oxidative hair dyes based on a carrier material and a dye mixture dissolved therein, the carrier substance being for- med from (1) 16 to 30% by weight of a mixture of a) 0.2 to 0.5% by weight of at least one physiologically acceptable water- soluble inorganic salt, b) 1.4 to 5.0% by weight of sodium-lauryl alcohol-diglycol ether sulphate, c) 0.5 to 6.0% by weight of coconut fatty acid diethanol amide, d) 4.0 to 14.0% by weight of a mixture of 60 to 80 parts by weight of cetyl stearyl alcohol, 10 to 30 parts by weight of glycerin monodistearate and 0 to 20 parts by weight of wool wax alcohol and e) 0.1 to 2.0% by weight of quaternisized homopolymer of dimethyl-amino-ethyl methacryl- ate, (2) 56 to 83% by weight of water, 3) 0.1 to 5.0% by weight of ammonia, (4) 0 to 5% by weight of aliphatic alcohol, (5) 0 to 1% by weight of perfume oil and (6) 0 to 0.5% by weight of a complexing agent for heavy metals. The oxidative hair dye has a relatively low viscosity, it is rapidly miscible with the hydrogen peroxide solution and can be readily distributed in the hair. It has a disentangling and smoothing effect on the hair and upon application it can be easily and completely rinsed from the hair. Even upon lengthy storage the agent allows no tendency to thicken and it has the same final viscosity substan- tially independent of type and amount of dye or electrolyte addition.
