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 C 1 -C 4 aliphatic alcohol.

First claim

We claim:

1 . A method comprising:
improving stability properties of a solid anhydrous composition for keratin fibres by dissolving the at least one fatty acid soap in at least one polyol compound, that is liquid at 20° C., to prepare the solid anhydrous composition, cooling the prepared solid anhydrous composition, and homogeneously mixing the prepared and cooled solid anhydrous composition, wherein the at least one polyol compound is present at a concentration of 50% or more by weight and the at least one fatty acid soap is present at a concentration of 5% or more, all values are calculated to total composition, wherein the solid anhydrous composition is free of volatile organic solvents.

2 . The method according to claim 1 , wherein the at least one polyol compound is selected from compounds according to the general formula

wherein n is a number between 1 and 20.

3 . The method according to claim 1 , wherein the at least one polyol compound is in accordance with the following general formula

wherein n is a number between 1 and 20 and
the solid anhydrous composition further comprises another polyol compound according to following general formula
H(OCH 2 CH 2 ) n OH

wherein n is a number between 1 and 20, wherein the at least one polyol compound to the another polyol compound are present at a weight ratio between 10:1 to 1:10.

4 . The method according to claim 1 , wherein the at least one fatty acid soap is at least one fatty acid sodium soap.

5 . The method according to claim 1 , wherein the solid anhydrous composition, having improved stability properties, is semi-transparent or transparent wherein transparency is judged macroscopically at a composition thickness of 1 cm.

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

7 . The method according to claim 1 , further comprising:
combining the prepared solid anhydrous composition with at least one silicone compound prior to the cooling of the prepared solid anhydrous composition.

8 . The method according to claim 1 , further comprising:
combining the prepared solid anhydrous composition with at least one fatty acid fatty alcohol ester prior to the cooling of the prepared solid anhydrous composition, wherein the at least one fatty acid fatty alcohol ester is 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.

9 . The method according to claim 1 , further comprising:
combining the prepared solid anhydrous composition with at least one surfactant selected from non-ionic, anionic and amphoteric ones prior to the cooling of the prepared solid anhydrous composition.

10 . The method according to claim 9 , wherein the at least one surfactant is one selected from a non-ionic surfactant and an anionic surfactant.

11 . The method according to claim 1 , further comprising:
combining the prepared solid anhydrous composition with at least one UV filter prior to the cooling of the prepared solid anhydrous composition.

12 . The method according to claim 1 , further comprising:
combining the prepared solid anhydrous composition with at least one direct dye prior to the cooling of the prepared solid anhydrous composition.

13 . The method according to claim 1 , wherein the solid anhydrous composition, having improved stability properties, has a penetration value between 1 and 30 mm determined with a penetrometer at 20° C.

14 . The method according claim 13 , wherein the penetration value is between 2 and 20 mm determined with a penetrometer at 20° C.

15 . The method according to claim 14 , wherein the penetration value is between 5 and 20 mm determined with a penetrometer at 20° C.

16 . A process for conditioning and styling keratin fibres, comprising:
applying the solid anhydrous composition, having improved stability properties, according to claim 1 onto wet or dry keratin fibres, and not rinsing off.

17 . A method comprising:
improving stability properties of a solid anhydrous composition for keratin fibres by dissolving the at least one fatty acid soap in at least one polyol compound, that is liquid at 20° C., to prepare the solid anhydrous composition, cooling the prepared solid anhydrous composition, and homogeneously mixing the prepared and cooled solid anhydrous composition, wherein the at least one polyol compound is present at a concentration of 50% or more by weight and the at least one fatty acid soap is present at a concentration of 5% or more, all values are calculated to total composition, wherein the solid anhydrous composition is free of volatile organic solvents, wherein the solid anhydrous composition, having improved stability properties, is stable over 6 months in a temperature range of 5 to 40° C., (isotherm storage).
