Abstract

The present invention is directed to a composition comprising a combination of surfactants for cleansing keratin fibers, a method for cleansing, use of the composition for cleansing, and kit-of-parts thereof. It has been found that the combination of two anionic surfactants, an amphoteric surfactant, and a diol compound provide a rich foam and superior color retention on pre-colored hair.

First claim

8. The aqueous composition of claim 7 , wherein a total inorganic, monovalent salt concentration is from 0.1% to 3.0% by weight, calculated to the total of the aqueous composition.

9. The aqueous composition of claim 1 , further comprising:
one or more foaming non-ionic surfactant(s) that is/are different from surfactants a) to c) and compound d), at a total concentration from 0.01% to 2% by weight, calculated to the total of the aqueous composition.

10. The aqueous composition of claim 1 , wherein the first anionic surfactant is sodium lauroyl sarcosinate, the second anionic surfactant is sodium laureth sulfate with 1-5 ethylene oxide units, the amphoteric surfactant is lauryl hydroxysultaine, and a total concentration of surfactants a) to c) is from 8% to 18% by weight, calculated to the total of the composition.

11. The aqueous composition of claim 1 , further comprising:
