Abstract
The invention concerns a cosmetic composition comprising at least an aromatic compound and at least an agent for dissolving said aromatic compound, characterized in that said dissolving agent consists of perfluorinated hydrofluoroether preferably having a total number of carbon atoms not less than 5 and consisting of a perfluoroalkane chain, branched or not, cyclized or not, bound to an alkoxy group, said alkoxy group having a number of atom(s) between 1 and 7, said hydrofluoroether having a boiling point in atmospheric pressure ranging between +15° C. and +100° C. The invention enables the replacement of ethanol conventionally used in cosmetic compositions by at least one hydrofluoroether compound.
