Patent ID: 7138128

Claim:
A water-in-oil emulsion (a) with a content of water and optionally water-soluble substances totalling greater than 85% by weight, and with a content of lipids, emulsifiers and lipophilic constituents of less than 15% by weight, in each case based on the total weight of the preparations, (b) comprising at least one surface-active substance selected from the group consisting of substances of the general formula (I) where A and A′ are identical or different organic radicals selected from the group consisting of branched and unbranched, saturated and unsaturated alkyl and acyl radicals and hydroxyacyl radicals having 10–30 carbon atoms, and the group consisting of hydroxyacyl groups bonded together via ester functions, according to the scheme where R′is selected from the group consisting of branched and unbranched alkyl groups having 1 to 20 carbon atoms, and R″ is selected from the group consisting of branched and unbranched alkylene groups having 1 to 20 carbon atoms, and b is a number from 0 to 200, a is a number from 1 to 100, X is a single bond or the group R 1 and R 2 independently of one another are selected from the group consisting of H and methyl, R 3 is selected from the group consisting of H, and of branched and unbranched, saturated and unsaturated alkyl- and acyl radicals having 1–20 carbon atoms, (c) additionally comprising at least one cationic polymer, wherein said at least one cationic polymer is selected from the group consisting of cationic cellulose derivatized with a quaternary ammonium salt, cationic starch, copolymers of diallylammonium salts and acrylamides, quaternized vinylpyrrolidone/vinylimadazole polymers, condensation products of a polyglycol with an amine, quaternized collagen polypeptides, quaternized wheat polypeptides, polyethyleneimine, cationic silicone polymers, copolymers of adipic acid with dimethylaminohydroxypropyldiethylenetriamine, copolymers of acrylic acid with dimethyldiallylammonium chloride, polyaminopolyamides, and cationic guar gum.
