Leave-In Hair Conditioning Composition

Abstract

Present invention relates to a single-phase, transparent, non-aerosol and non-aqueous leave-in conditioning composition for hair, especially for strongly damaged hair by chemical processes such as permanent shaping, oxidative colouration and bleaching. Accordingly, conditioning compositions of present invention comprise one or more cyclomethicone at a concentration of at least 50% by weight calculated to total composition, and at least one di alkyl carbonate.

1 . A non-aqueous composition for hair comprising one or more cyclomethicone of the formula 
       
         
           
           
               
               
           
         
       
       where n is a number between 3 and 7, at a concentration of between 55 to 90% by weight, calculated to total composition, and at least one dialkyl carbonate of the formula
   R 1 OC(O)OR 2    
 
       where R1 and R2 are independent from each other linear or branched saturated or unsaturated alkyl chains with 6 to 22 C atoms, wherein the composition is single-phase, transparent and non-aerosol. 
     
     
         2 . (canceled) 
     
     
         3 . A composition according to  claim 1  comprising at least one dialkyl carbonate at a concentration between 0.1 and 20% by weight calculated to total composition. 
     
     
         4 . A composition according to  claim 1  characterised in that it comprises additionally at least one further silicone compound selected from dimethicone and dimethiconol at a concentration of 0.1 to 20% by weight, calculated to total composition. 
     
     
         5 . A composition according to  claim 1  comprising at least one arylated silicone at a concentration of 0.1 to 10% by weight, calculated to total composition. 
     
     
         6 . A composition according to  claim 1  comprising at least one ester of aliphatic or branched, saturated or unsaturated carboxylic acid with 12 to 22 C atoms with a primary or secondary linear or branched saturated or unsaturated alcohol with 3 to 18 C atoms at a concentration of 0.1 to 5% by weight, calculated to total composition. 
     
     
         7 . A composition according to  claim 1  comprising at least one natural oil. 
     
     
         8 . A composition according to  claim 1  comprising at least one at least one UV filter. 
     
     
         9 . A composition according to  claim 1  comprising at least one at least one organic solvent. 
     
     
         10 . A composition according to  claim 1  wherein the composition is a leave in conditioner. 
     
     
         11 . (canceled) 
     
     
         12 . (canceled) 
     
     
         13 . (canceled) 
     
     
         14 . A composition according to  claim 1  wherein the cyclomethicone is present at a concentration of between 60% to 85% by weight. 
     
     
         15 . A composition according to  claim 14  wherein the cyclomethicone is present at a concentration of between 70% to 80% by weight.
