Use of a volatile polyfluorinated solvent as a drying accelerator in cosmetic products

Abstract

Use of a volatile organic polyhalogen solvent, in which the halogen atom is fluorine, in a cosmetic makeup, sun protection or nailcare composition. The composition contains the said organic polyhalogen solvent as a drying accelerator, the latter having a vapour pressure of more than 20 mbar (2000 Pa) at 25° C. The composition, which can be in anhydrous form or in the form of an emulsion, leads to very rapid drying.

1 . Use in a cosmetic makeup, sun protection or nailcare composition of at least one volatile organic polyhalogen solvent as a drying accelerator, the halogen atom being fluorine and the said solvent having a vapour pressure of more than 20 mbar (2000 Pa) at 25°C.

 t is 0 or 1,  
 n is 0, 1, 2 or 3,  
 X is a linear or branched divalent perfluoroalkyl radical having 2 to 5 carbon atoms, and  
 Z represents O, S or NR, where R is hydrogen or a radical —(CH 2 ) n —CH 3  or —(CF 2 ) m —CF 3 , where m is 2, 3, 4 or 5.

         6 . Use according to    claim 1   , characterized in that the said volatile solvent is a perfluoroalkane compound of the following formula: 
       CF 3 —(CF 2 ) n —CF 3   (III) 
       in which: 
 n is from 2 to 6.  
 
     
     
         7 . Use according to    claim 6   , characterized in that the perfluoroalkane compound is dedecafluoropentane or tetradecafluorohexane.  
     
     
         8 . Use according to    claim 1   , characterized in that the said volatile solvent is a perfluoromorpholine derivative of the formula:  
                   
       in which: 
 R is a C 1 -C 4  perfluoroalkyl radical.  
 
     
     
         9 . Use according to    claim 8   , characterized in that the perfluoromorpholine derivative is 4-trifluoromethylperfluoromorpholine or 4-pentafluoroethylperfluoromorpholine.  
     
     
         10 . Use according to any one of the preceding claims, characterized in that the volatile solvent is present in the composition in a proportion of between 2 and 98% by weight relative to the total weight of the composition.  
     
     
         11 . Use according to any one of the preceding claims, characterized in that the composition comprises at least one pigment and/or dye and/or filler in particle form.  
     
     
         12 . Use according to    claim 11   , characterized in that the proportion of pigment and/or dye in the composition is between 0.1 and 15% by weight relative to the total weight of the composition.  
     
     
         13 . Use according to    claim 11   , characterized in that the proportion of filler in the composition is no more than 98% by weight relative to the total weight of the composition.
