Abstract

The present invention relates to an aqueous cosmetic powder composition especially designed for styling hair comprising water, hydrophobic colloidal silica and a water soluble non-ionic polyol having at least three hydroxyl groups and is solid at ambient temperature.

First claim

1 - 12 . (canceled)

13 . A process for styling and/or setting hair comprising a step of applying onto dry hair an aqueous powder cosmetic composition,
wherein said composition comprises water, hydrophobic colloidal silica and a water-soluble non-ionic polyol having at least three hydroxyl groups and is solid at 25° C.

14 . A process for producing an aqueous powder cosmetic composition which comprises water, hydrophobic colloidal silica and a water-soluble non-ionic polyol having at least three hydroxyl groups and is solid at 25° C., the process comprising the steps of
dissolving the polyol in water, and
adding thereto the hydrophobic colloidal silica, and
mixing at high shear rate at ambient temperature.

15 . A kit for hair comprising an aqueous powder cosmetic composition which comprises water, hydrophobic colloidal silica and a water-soluble non-ionic polyol having at least three hydroxy groups and is solid at 25° C.

16 . The process according to claim 13 , wherein the composition comprises less than 80% by weight of water, calculated to the total of the composition.

17 . The process according to claim 13 , wherein the composition comprises up to 15% by weight of hydrophobic silica, calculated to the total of the composition.

18 . The process according to claim 13 , wherein the hydrophobic silica has a BET specific surface area in the range of 190 to 250 m2/g, and tamped density in the range of 55 to 65 g/L, according to DIN EN ISO 787/11 of August 2013.

19 . The process according to claim 13 , wherein the polyol has at least five hydroxyl groups.

20 . The process according to claim 13 , wherein the polyol is selected from sorbitol, saccharose, glucose, lactose and fructose.

21 . The process according to claim 13 , wherein the polyol is sorbitol.

22 . The process according to claim 13 , wherein the composition comprises the polyol at a concentration up to 45% by weight, calculated to the total of the composition.

23 . The process according to claim 13 , wherein the composition comprises one or more film forming and/or setting polymer.

24 . The process according to claim 13 , wherein the composition comprises one or more hair direct dyes.

25 . The process according to claim 13 , wherein the composition comprises one or more UV filter.

26 . The process of claim 13 , wherein the polyol is present in the composition in an amount greater than 20 wt %.

27 . The process of claim 13 , wherein the polyol is present in the composition in an amount of 21 to 45 wt %.

28 . The process of claim 13 , wherein the hydrophobic colloidal silica is present in the composition in an amount of 7 wt % or greater.

29 . The process of claim 28 , wherein the hydrophobic colloidal silica is present in the composition in an amount of 10 wt % or greater.
