Claim:
A composition for coloring keratin fibers comprising (a) at least one tenside of formula (I) wherein y is an integer from 0 to 2, x is an integer from 1 to 3, and the sum of x and y is 3, wherein M is hydrogen, an alkali metal, alkaline earth metal, or an ammonium cation, or an alkyl radical having 1 to 4 carbon atoms that is optionally substituted by one or more hydroxyl groups, wherein B is a physiologically compatible anion, and wherein R is a radical of formula (II), in which z is an integer from 1 to 4, R 1 and R 2 , independently of one another, are a C 1 to C 4 alkyl radical, that is optionally substituted by one or more hydroxyl groups, or an acyl group, A is —O—CH 2 —CH 2 —CH 2 —, —O—CH 2 —CH 2 — or —O—CH 2 —CHOH—CH 2 —, and R 3 is a branched or unbranched, saturated C 8 to C 18 acyl radical, or a branched or unbranched, monounsaturated or polyunsaturated C 8 to C 18 acyl radical; (b) at least one conditioning component comprising a cationic polymer; and (c) at least one dye or dye precursor, or combinations thereof.
