Solid W/O emulsions at room temperature, containing with respect to the total preparation (a) a fatty phase comprising (a1) at least one oil component, the oil components being found in a content of 1% to 20% in weight, (a2) at least one wax component, the wax components being in a content of 5% to 20% by weight and the ratio of oil components to wax components being between 3:1 and 1:3 , (b) an aqueous phase comprising (b1) from % to 65% by weight of water as well as (b2) from 4% to 40% by weight of a skin moisturizing agent selected from the group of glycerol, chitosan, fucogel, propylene glycol, polyethylene glycol, dipropylene glycol, butylene glycol, mannitol, lactic acid, polyethylene glycol, glycine, sodium pyrrolidone carboxylate, hyaluronic acid, salts of the listed acids as well as urea and salts of metals of the first and second main groups, (c) ( c) a W/O emulsifier or a mixture of various s W/O emulsifiers, selected from the group of surface-active substances with the general structure A-B-A', in which A and A' represent the same or different hydrophobic organic residues and B represents a hydrophilic group, the emulsifier(s) being found in concentrations of up to 5% by weight and (d) (d) stabilizers selected from the group of substances with the general formula **Formula** in which - A'" and A'''' represent the same or different hydrophobic organic residues, - a represents a number from 1 to 100, - X represents a single bond or the group ,**Formula** - R1 and R2 independently of one another are selected from the group of H, methyl, but such that the two moieties do not simultaneously represent methyl, - R3 is selected from the group H, as well as from branched and unbranched, saturated and unsaturated alkyl and acyl radicals having 1-20 carbon atoms, - where the radicals A'''' and A'''' they can be the same or different and are selected from the **Formula** group - in which e R8 and R9 can be the same or different and are selected from the group of saturated and unsaturated alkyl and acyl radicals with 1-30 carbon atoms, p represents a number from 1-20 and Y represents a single bond or the group, * *Formula** - in which R3 is selected from the group H, as well as branched and unbranched, saturated and unsaturated alkyl and acyl radicals with 1-30 carbon atoms, in addition to groups A''' and A" " can also represent alkyl radicals or acyl radicals, independently of one another, in concentrations of 0.01% to 5% by weight. |
