Fluorinated hydrocarbon compounds have formula (I):RF-(CH2)n-X-[C3H5(OH)]-(Y)x-RH,in which C3H5(OH) represents structures (Ia) or (Ib): <IMAGE> (Ia) <IMAGE> (Ib) RF is a perfluorinated C4-C20 alkyl radical or a mixture of perfluorinated C4-C20 radicals; RH is a straight or branched C1-C22 alkyl radical or a mixture of straight or branched C1-C22 alkyl radicals or an aryl or aralkyl radical; n is from 0 to 4; X stands for O, S, <IMAGE> x stands for 0 or 1; Y stands for O, S, (a) or (b); with the proviso that when X=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. |
