Abstract
The present invention relates to a composition for coloring keratin fibers and a method of use thereof. The coloring composition contains at least one phosphate-based tenside of a particular formula, at least one conditioning component, and at least one dye and/or dye precursor.
Claims15
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, R1 and R2, independently of one another, are a C1 to C4 alkyl radical, that is optionally substituted by one or more hydroxyl groups, or an acyl group, A is —O—CH2—CH2—CH2—, —O—CH2—CH2— or —O—CH2—CHOH—CH2—, and R3 is a branched or unbranched, saturated C8 to C18 acyl radical, or a branched or unbranched, monounsaturated or polyunsaturated C8 to C18 acyl radical;
- (b) at least one conditioning component comprising a cationic polymer;
- and
- (c) at least one dye or dye precursor, or combinations thereof.
