Long wear cosmetic composition

Abstract

The present invention relates to long-wearing, non-aqueous based cosmetic compositions, and related dermatological, pharmaceutical or hygiene compositions. The present invention provides a non-aqueous based composition comprising one or a mixture of two or more emulsifiers.

1 . A non-aqueous composition comprising an emulsifier.  
   
   
       2 . The composition of  claim 1 , wherein the emulsifier is selected from fatty acids, glyceryl esters, ethoxylated surfactants, phosphate esters of alcohols, or mixtures thereof.  
   
   
       3 . The composition of  claim 3 , wherein the emulsifier is selected from stearic acid, glyceryl stearate, polysorbate 20, sodium dihydroxycetyl phosphate or mixtures thereof.  
   
   
       4 . The composition of  claim 3 , wherein the emulsifier is present in 0.2 to 10 wt % of the total composition.  
   
   
       5 . The composition of  claim 3 , further comprising a film former.  
   
   
       6 . The composition of  claim 3 , further comprising a wax.  
   
   
       7 . The composition of  claim 3 , further comprising a thickening agent.  
   
   
       8 . The composition of  claim 3 , further comprising a filler.  
   
   
       9 . The composition of  claim 3 , further comprising a solvent.  
   
   
       10 . The composition of  claim 3 , further comprising a colorant.  
   
   
       11 . The composition of  claim 5 , wherein the film former is selected from styrene block copolymers, alkyl acrylate copolymers, polyamide resins or mixtures thereof.  
   
   
       12 . The composition of  claim 6 , wherein the wax is selected from paraffin, carnuba wax, beeswax, synthetic beeswax or mixtures thereof.  
   
   
       13 . A method for preparing a non-aqueous composition comprising an emulsifier, comprising adding an emulsifier to an non-aqueous medium.  
   
   
       14 . The method of  claim 13 , wherein the emulsifier is selected from fatty acids, glyceryl esters, ethoxylated surfactants, phosphate esters of alcohols, or mixtures thereof.  
   
   
       15 . The method of  claim 14 , wherein the emulsifier is selected from stearic acid, glyceryl stearate, polysorbate 20, sodium dihydroxycetyl phosphate or mixtures thereof.  
   
   
       16 . A mascara composition comprising the composition of  claim 1 .  
   
   
       17 . The mascara composition of  claim 16 , wherein the emulsifier is selected from fatty acids, glyceryl esters, ethoxylated surfactants, phosphate esters of alcohols, or mixtures thereof.  
   
   
       18 . The mascara composition of  claim 17 , wherein the emulsifier is selected from stearic acid, glyceryl stearate, polysorbate 20, sodium dihydroxycetyl phosphate or mixtures thereof.  
   
   
       19 . An eyeliner composition comprising the composition of  claim 2 .  
   
   
       20 . A method of making-up the eyes, hair, lips and/or skin comprising applying the composition of  claim 2  to the respective surface.
