Abstract
Improved wet combability of hair is achieved by aqueous colorants for keratin fibers, such as pelts and human hair, based on oxidation dye precursors, which are mixed with a peroxide-containing composition, immediately before use, containing at least one developer substance and at least one coupler substance, and also tris(3-N,N-dimethyl-N-linolenamidopropyl-2-hydroxyammoniumpropyl)phosphori c acid ester-trichloride as a hair care composition. The colored keratin fibers do not show the customary known damage.

A dyeing cream, comprising a cream base containing at least one of cetyl alcohol, polyacrylic acid, potassium oleate, polymethacrylic acid, decyl oleate, glycerol mono-stearate, polyoxyethylene(10) oleyl ether, polyoxyethylene(30) cetyl/stearyl ether, polyoxyethylene(3) lauryl ether, cetyl/stearyl alcohol, sodium cetyl/stearyl sulphate, polyoxyethylene(40) castor oil, solvents, a reducing agent and an alkalizing agent, said dyeing cream containing at least one developer substance, at least one coupler substance and 0.1 to 5% by weight of tris(3-N,N-dimethyl-N-linolenamidopropyl-2-hydroxyammoniumpropyl)phosphori c acid ester-trichloride.
A two component package product for the dyeing of hair comprising one component comprising a developer, a coupler and 0.1 to 5% by weight of tris(3-N,N-dimethyl-N-linolenamidopropyl-2-hydroxyammoniumpropyl)phosphori c acid ester-trichloride and a second component comprising a source of hydrogen peroxide.
