Abstract
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)phosphoric acid ester-trichloride as a hair care composition. The colored keratin fibers do not show the customary known damage.

Claim 2
Dependent Claim
53 words
An aqueous dyeing composition for keratin fibers, based on oxidation dye precursors, which is mixed immediately before application with a peroxide-containing composition to form a total composition, comprising at least one developer substance and at least one coupler substance, and 0.1 to 5% by weight of the total composition of tris(3-N,N-dimethyl-N-linolenamidopropyl-2-hydroxyammoniumpropyl)phosphoric acid ester-trichloride.
Claim 3
Dependent Claim

Claim 8
Dependent Claim
35 words
A method of applying tris(3-N,N-dimethyl-N-linolenamidopropyl-2-hydroxyammoniumpropyl)phosphoric acid ester-trichloride to the hair in order to eliminate the need for applying a conditioner to freshly dyed hair comprising treating hair with a dyeing composition according to claim 1.
