Abstract

The invention relates to new cosmetic and/or pharmaceutical formulations containing(a) dialkyl carbonates corresponding to formula (I): in which R1 is a linear alkyl and/or alkenyl group containing 6 to 22 carbon atoms, a 2-ethylhexyl, isotridecyl or isostearyl group or a group derived from a polyol containing 2 to 15 carbon atoms and at least two hydroxyl groups, R2 has the same meaning as R1 or is an alkyl group containing 1 to 5 carbon atoms and n and m independently of one another stand for 0 or numbers of 1 to 100, and(b) emulsifiers.The formulations are distinguished by particular sensorial properties, the dialkyl carbonates proving to be as effective as the silicone oils which they are intended to replace.
