Abstract
Fluorinated hydrocarbon compounds have formula (I): EQU R.sub.F --(CH.sub.2).sub.n --X--C.sub.3 H.sub.5 (OH)!--(Y).sub.x --R.sub.H , in which C.sub.3 H.sub.5 (OH) represents structures (Ia) or (Ib): ##STR1## R.sub.F is a perfluorinated C.sub.4 -C.sub.20 alkyl radical or a mixture of perfluorinated C.sub.4 -C.sub.20 radicals; R.sub.H is a straight or branched C.sub.1 -C.sub.22 alkyl radical or a mixture of straight or branched C.sub.1 -C.sub.22 alkyl radicals or an aryl or aralkyl radical; n is from 0 to 4; X stands for O, S, ##STR2## x stands for 0 or 1; Y stands for O, S, (a) or (b); with the proviso that when X.dbd.S, (a) or (b), Y is not S, (a) or (b). The use of said compounds as amphiphilic compounds, the method of preparing them, and the cosmetic compositions containing them are also disclosed.
