Abstract
Abstract The invention relates to a hair colorant comprised of a flowable, aqueous preparation of oxidation colorant intermediate products (A) and a flowable, aqueous oxidation agent preparation (B) which are mixed in a weight ratio A:B=1:2 to 2:1 to produce a gel-forming coloring batch immediately before applying on the hair. As supporting components in the oxidation colorant preparation, the hair colorant comprises 3.0 to 15 wt. % of a saturated or unsaturated, linear or branched alcohol with 8 to 36 C-atoms, 0.1 to 20 wt. % of a low-molecular water-soluble alcohol, 0.1 to 15 wt. % of a liquid fatty acid with 16 to 22 C-atoms in the form of a water-soluble soap, 0.1 to 20 wt. % of an addition product of 1 to 5 mole ethylene oxide on a linear fatty alcohol with 8 to 22 C-atoms and/or 0.1 to 15 wt. % of an optional alkoxylated amine. The oxidation agent preparation (B) preferably comprises 3 to 12 wt. % hydrogen peroxide, 0.1 to 5 wt. % of a water-soluble, synthetic tenside and 1 to 5 wt. % of a dispersed acrylic acid polymerizate or copolymerizate and/or methacrylic acid polymerizate or copolymerizate.
