US 5,705,165 A · Cosmetic compositions containing hydrofluorocarbon compounds

Abstract

The present invention concerns the use in a cosmetic composition of a hydrofluorocarbon compound with formula (I): R.sub.F --(CH.sub.2).sub.n --X--C.sub.3 H.sub.5 (OH)!--Y--R.sub.H(I) where C.sub.3 H.sub.5 (OH) represents the structures: ##STR1## R.sub.F represents a perfluorinated C.sub.4 -C.sub.20 alkyl radical or a mixture of perfluorinated C.sub.4 -C.sub.20 alkyl radicals; R.sub.H represents a linear or branched C.sub.1 -C.sub.22 alkyl radical or a mixture of linear or branched C.sub.1 -C.sub.22 alkyl radicals, an aryl radical or an aralkyl radical; n is between 0 and 4; X and Y represent ##STR2## It also concerns certain sulfoxide and sulfone compounds and cosmetic compositions including the compounds of the invention.
