Abstract:
A process for accelerating the drying time of an anhydrous cosmetic make-up, sun-protection or nail care composition which consists of introducing, into said composition, a sufficient amount, for enabling a rapid drying, of at least one volatile organic solvent selected from the group consisting of a fluoroalkyl and heterofluoroalkyl compound having the following formula:CH.sub.3 --(CH.sub.2).sub.n --[Z].sub.t --X--CF.sub.3in which:X is linear or branched divalent perfluoroalkyl radical having 2 to 5 carbon atoms,Z represents O, S or NR where R is hydrogen or a radical --(CH.sub.2).sub.n --CH.sub.3 or --(CF.sub.2).sub.m --CF.sub.3,where m is 2, 3, 4 or 5, n is 0, 1, 2, or 3 and t is 0 or 1,the said volatile organic solvent having a vapor pressure of more than 20 m bar (2000 Pa) at 25.degree. C. and a boiling point between 20.degree. C. and 75.degree. C.
