Aqueous cosmetic powder composition

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.

1 . An aqueous powder cosmetic composition for hair comprising water, hydrophobic colloidal silica and a water soluble non-ionic polyol having at least three hydroxyl groups and is solid at 25° C. 
     
     
         2 . The composition according to  claim 1 , comprising less than 80% water calculated to the total of the composition. 
     
     
         3 . The composition according to  claim 1 , comprising up to 15% calculated to the total of the composition, hydrophobic colloidal silica. 
     
     
         4 . The composition according to  claim 1 , wherein the hydrophobic colloidal 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. 
     
     
         5 . The composition according to  claim 1 , wherein the water soluble non-ionic polyol solid at 25° C. has at least five hydroxyl groups. 
     
     
         6 . The composition according to  claim 1 , wherein the water soluble non-ionic polyol solid at 25° C. is selected from sorbitol, saccharose, glucose, lactose and fructose. 
     
     
         7 . The composition according to  claim 6 , wherein the water soluble non-ionic polyol solid at 25° C. is sorbitol. 
     
     
         8 . The composition according to  claim 1 , comprising the water soluble non-ionic polyol solid at 25° C. at a concentration up to 45%, calculated to the total of the composition. 
     
     
         9 . The composition according to  claim 1 , further comprising one or more film forming and/or setting polymer, selected from anionic, cationic, non-ionic and amphoteric ones, at a concentration in the range of 0.1 to 10% by weight calculated to the total of the composition. 
     
     
         10 . The composition according  claim 1 , further comprising one or more hair direct dyes, selected from anionic, cationic and non-ionic nitro dyes. 
     
     
         11 . The composition according to  claim 1 , further comprising one or more UV filter. 
     
     
         12 . (canceled) 
     
     
         13 . Process for styling and/or setting hair comprising the step of applying onto dry hair the composition according to  claim 1 . 
     
     
         14 . Process for producing the composition according to  claim 1 , comprising the steps of dissolving the water soluble polyol with at least three hydroxyl groups and is solid at 25° C. in water and adding thereto the hydrophobic colloidal silica, and mixing at high shear rate at ambient temperature. 
     
     
         15 . (canceled)
