摘要：
Water-in-oil emulsions (a) with a content of water and optionally water-soluble substances totalling at least 75% by weight, and with a content of lipids, emulsifiers and lipophilic constituents totalling at most 25%, preferably at most 20%, based in each case on the total weight of the preparations, (b) whose oil phase is chosen from the group of lipids or lipid mixtures, where the total polarity of the lipid phase is between 20 and 30 mN/m, (c) comprising at least one interface-active substance, chosen from the group of alkylmethicone copolyols and/or alkyldimethicone copolyols, (d) optionally, but particularly when the content of water and water-soluble (hydrophilic) constituents is between 75 and 80% by weight, comprising one or more cationic polymers.
