Abstract

Present invention is on an anhydrous solid conditioning and styling, composition for keratin fibres, especially human hair. The object of the present invention is a solid anhydrous composition for keratin fibres, especially for human hair, comprising at least one polyol liquid at 20° C. at a concentration 50% or more by weight and at least one fatty acid soap at a concentration of 5% or more by weight, all values calculated to total composition, wherein the composition is free of volatile organic solvents, especially C1-C4 aliphatic alcohol.

First claim

We claim:

1. A method for conditioning and styling human hair, the method comprising:
providing a solid anhydrous composition comprising:
at least one polyol liquid at 20° C. selected from compounds according to general formulas:

wherein n is a number between 1 and 20 at a concentration of at least 70% by weight; and
fatty acid sodium soap at a concentration of 5% to 20%, all values are calculated to a total of the solid anhydrous composition,
wherein the solid anhydrous composition is free of volatile organic solvents comprising C 1 -C 4 aliphatic alcohol.

2. The method according to claim 1 , wherein the solid anhydrous composition further comprises:
at least one film forming styling polymer that is soluble in the solid anhydrous composition at 20° C. and present at a concentration of 0.1 to 10% by weight calculated to the total of the solid anhydrous composition.

3. The method according to claim 1 , wherein the solid anhydrous composition further comprises:
at least one silicone compound.

4. The method according to claim 1 , wherein the solid anhydrous composition further comprises:
at least one fatty acid fatty alcohol ester in accordance with the following general formula
R 1 —C(O)—O—R 2

wherein R 1 is straight or branched, saturated or unsaturated with 8 to 22 carbon atoms and R 2 is straight or branched, saturated or unsaturated 1 to 6 carbon atoms.

5. The method according to claim 1 , wherein the solid anhydrous composition further comprises:
at least one surfactant selected from non-ionic surfactant, anionic surfactant, and amphoteric surfactant.

6. The method according to claim 5 , wherein the at least one surfactant is one selected from a non-ionic surfactant and an anionic surfactant.

7. The method according to claim 1 , wherein the solid anhydrous composition further comprises:
at least one UV filter.

8. The method according to claim 1 , wherein the solid anhydrous composition further comprises:
at least one direct dye.
