Personal care composition

Abstract

An aqueous shear-thinning personal care composition comprises: (a) at least 3 wt % of a sulfonate compound of general formula (I): where R 1 represents a C 8-22 alkyl group alkyl group; R 2 represents a C 1-4 alkyl group; each of R 3 , R 4 and R 5 independently represents a hydrogen atom or a C 1-4 alkyl group; and M + represents a sodium or potassium cation; (b) at least 3 wt % of an amphoteric or zwitterionic surfactant; (c) at least 10 wt % of water; and (d) at least 0.5 wt % of an additional component in the form of particles or droplets suspended in the composition. The composition is stable in an aqueous environment and can be formulated with a wide range of additional components.

1 . An aqueous shear-thinning personal care composition comprising:

         where R 1  represents a C 8-22  alkyl group; 
         R 2  represents a C 1-4  alkyl group; 
         each of R 3 , R 4  and R 5  independently represents a hydrogen atom or a C 1-4  alkyl group; and 
         M +  represents a cation; 
         (b) at least 3 wt % of an amphoteric or zwitterionic surfactant; 
         (c) at least 10 wt % of water; and 
         (d) at least 0.5 wt % of an additional component in the form of particles or droplets suspended in the composition. 
       
     
     
         2 . A composition as claimed in  claim 1  wherein R 2  represents a methyl group. 
     
     
         3 . A composition as claimed in  claim 1  wherein each of R 3 , R 4  and R 5  represents a hydrogen atom. 
     
     
         4 . A composition as claimed in  claim 1  wherein component (a) is present in an amount of up to 30 wt %. 
     
     
         5 . A composition as claimed in  claim 1  wherein component (b) is present in an amount of up to 30 wt %. 
     
     
         6 . A composition as claimed in  claim 1  wherein component (c) is present in an amount of from 20% to 95% by total composition weight. 
     
     
         7 . A composition as claimed in  claim 1  wherein component (d) is present in an amount from 0.1 wt % to 50 wt %. 
     
     
         8 . A composition as claimed in  claim 1 , wherein said additional component (d) is a benefit agent. 
     
     
         9 . A composition as claimed in  claim 1 , wherein the composition further includes a benefit agent which is in solution in the composition. 
     
     
         10 . A composition as claimed in  claim 1 , including an electrolyte. 
     
     
         11 . A composition as claimed in  claim 8  wherein the electrolyte is present in an amount from 0.5 wt % to 25 wt %. 
     
     
         12 . A composition as claimed in  claim 1 , formulated as a product selected from the following: a bath or shower gel; a hand washing composition; a facial washing composition; a pre-, during- or post-shaving product; a skin moisturiser; a hair gel; a medicinal skin treatment product; a shampoo; a hair conditioner; a dental product.
