Abstract

The oxidative hair dye composition is in the form of a cream and contains a carrier substance and a dye mixture dissolved in it. The dye mixture includes at least one coupler and at least one developer. The composition has a pH between 4.5 to 12.5 and, in addition to the dye mixture, contains (A) 10 to 30 percent by weight of at least one fatty alcohol with 10 to 24 carbon atoms; (B) 0.2 to 6.0 percent by weight of at least one diester of formula (I) EQU R.sub.1 --CO--O--(CH.sub.2 --CH.sub.2 --O).sub.n --CO--R.sub.2(I), where n is 1, 2 or 3, and R.sub.1 and R.sub.2 are each independently selected from the group consisting of alkyl groups with 12 to 20 carbon atoms; (C) 0.5 to 20 percent by weight glycerin fatty acid ester with 10 to 24 carbon atoms, and (D) 0.1 to 10 percent by weight of at least one emulsifier member selected from the group consisting of nonionic emulsifiers, anionic emulsifiers and ampholytic emulsifiers. The total content of fatty alcohol, of diester and of glycerin fatty acid ester is from 25.0 to 56.0 percent by weight.
