Abstract
The invention relates to gel-form cosmetic preparations containing (a) 5 to 50% by weight of surfactants; (b) 5 to 50% by weight of oils and/or waxes; (c) 0 to 15% by weight of water-soluble polyols; and component (a) contains at least 10% by weight, based on component (a) as a whole, of a mixture of citric acid esters of alkoxylated alcohols and the sum of components (a) and (b) in the preparation as a whole being from 10 to 70% by weight.
Claims19
A gel-form cosmetic preparation comprising:
- (a) 5 to 50% by weight of surfactants;
- (b) 5 to 50% by weight of oils and/or waxes;
- (c) 0 to 15% by weight of water-soluble polyols;
- wherein, component (a) contains at least 10% by weight, based on component (a) as a whole, of a mixture of citric acid esters of alkoxylated alcohols of the formula R1O(CH2CH2O)nH, wherein, R1 is a linear or branched alkyl or alkenyl group containing 4 to 24 carbon atoms, and n is a number of from 1 to 50 and a sum of components (a) and (b) in the preparation as a whole being from 10 to 70% by weight, and with the proviso that the ratio by weight of monoester to diester in the citric acid ester mixture is in a range of 3:1 to 10:1.
