Water-in-oil emulsions (a) with a maximum viscosity of 5,000 mPaus, (b) with a water content and water-soluble substances of at least 75% by weight in total, and with a lipid, emulsifier and Lipophilic components of a maximum of 15% in total, referring respectively to the total weight of the preparations, (c) whose oil phase comprises at least 75% by weight of one or more substances chosen from the group of - apolar lipids, liquid at room temperature , which have a polarity greater than 30 mN / m, and / or - silicone oils of any polarity, so that this weight percentage refers to the total weight of the oil phase, (d) which contains at least one substance surfactant, chosen from the group of substances of general formula (I) (See formula) - where A and A ¿represent the same or different organic radicals chosen from the group of branched and linear, saturated and unsaturated branched alkyl, acyl and hydroxyacyl radicals, of 10 -30 atom carbon, as well as the group of hydroxyacyl radicals linked together by ester functions according to the scheme (See formula) - where R is chosen from the group of branched and linear alkyl radicals of 1 to 20 carbon atoms, R group of branched and linear alkylene radicals of 1 to 20 carbon atoms, and b can take values from 0 to 200. |
