Abstract:
A water-in-oil emulsion comprising(a) an aqueous phase with a content of water and optionally water soluble substances totalling at least 70% by weight, and with a content of lipids, emulsifiers and lipophilic constitutents totalling at most 20% by weight, in each case based on the total weight of the aqueous phase, (b) a lipid phase whose polarity is between 20 and 45 mN/m, (c) at least one interface-active substance which is/are polyethers of an oligomeric or polymeric molecular unit B, the monomers of which are branched &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, (d) at least one cationic polymer.
