Device and formulation for hair

Abstract

Hair grooming device comprising a head, a nebuliser, a power supply therefore and a reservoir containing a composition to be applied to the hair during use by the nebuliser, the composition comprising a solution comprising hydrocarbon having an average carbon chain length of 13 or less and a benefit agent, and wherein the composition has a viscosity of 4.5 cSt or less 25° C.

1 . Hair grooming device comprising a head, a nebuliser, a power supply therefore and a reservoir containing a composition to be applied to the hair during use by the nebuliser, the composition comprising a solution comprising hydrocarbon having an average carbon chain length of 13 or less and a benefit agent, and wherein the composition has a viscosity of 4.5 cSt or less 25° C. 
     
     
         2 . Device according to  claim 1  in which the benefit agent is a silicone. 
     
     
         3 . Device according to  claim 2  in which the silicone has a viscosity below 500 cSt at 25° C. 
     
     
         4 . Device according to  claim 2  in which the total level of silicone within the composition is 1 wt % or below. 
     
     
         5 . Device according to  claim 1  in which the hydrocarbon has an average chain length from 8 to 12. 
     
     
         6 . Hair grooming device according to  claim 1  in which the head is bristle or tooth-bearing head. 
     
     
         7 . Device according to  claim 1  which is a brush. 
     
     
         8 . Device according to  claim 1  wherein the nebuliser comprises a gauze defined by a rigid ring, a reservoir for containing a composition to be nebulised and a circuit connected to the power supply. 
     
     
         9 . Device according to  claim 8  wherein the gauze is convex with regard to the reservoir. 
     
     
         10 . Device according to  claim 1  wherein the nebuliser is located within the head and the head also comprises an aperture for releasing the nebulised fluid during use on to the hair. 
     
     
         11 . Device according to  claim 1  comprising a handle which houses the power source. 
     
     
         12 . A process for depositing a hair benefit agent onto the hair, the process comprising the following steps:
 i) forming a composition comprising a hydrocarbon having an average carbon chain length of 13 or less and a benefit agent, and wherein the composition has a viscosity of less than 5 cSt at 25° C.   ii) nebulising the formulation using the apparatus described in any previous claim.
