Abstract: The use of a cyclic acetal obtained by reacting an aliphatic aldehyde having 2 to 4 carbon atoms with a polyol having 3 to 6 carbon atoms and at least three hydroxy functions, including two on vicinal carbons or carbons having one carbon atom therebetween, as a pharmaceutical or cosmetic carrier, is disclosed.

Abstract: Disclosed is a support, in particular for making topical cosmetic formulations comprising a mixture containing polyol esters with saturated linear acids and unsaturated linear and/or saturated branched acids, monounsaturated linear or saturated branched acid esters with saturated linear alcohols, saturated linear acid esters with monounsaturated linear or saturated branched alcohols, saturated linear and/or monounsaturated linear and/or saturated branched free alcohols, saturated linear ester acids and saturated linear alcohols, monounsaturated linear or saturated branched ester acids and monounsaturated linear or saturated branched linear alcohols, the linear saturated alcohols and acids having at least 20 carbon atoms and the monounsaturated or saturated branched alcohols and acids having at least 18 carbon atoms.
