Preparations of the W/O emulsion type with an increased water content, comprising moderately polar and/or nonpolar lipids and one or more interface-active polyethers of the A-O-B-O-A type
A water-in-oil emulsion ;(a) with a content of water and optionally water-soluble substances totaling at least 70% by weight, and with a content of lipids, emulsifiers and lipophilic constituents totaling at most 20%, in each case based on the total weight of the preparations, ;(b) with a lipid phase whose total polarity is between 20 and 45 mN/m, ;(c) comprising at least one interface-active substance chosen from the group of substances of polyethers of ;an oligomeric or polymeric molecular unit B, the monomers of which are branched or unbranched &agr;,&ohgr;-alkylene glycols (&agr;,&ohgr;-dihydroxyalkanes) having 3-25 carbon atoms and ;two units A composed of polyoxyethylene groups, ;where the molecular units A and B are linked together according to the scheme A-O-B-O-A via ether groups.
