Abstract

Cosmetic and dermatological preparations in the form of O/W emulsions, comprising(1) 0.1 up to 5% by weight, based on the total weight of the preparations, of one or more C14-C22-fatty acids,(2) 0.2 up to 10% by weight, based on the total weight of the preparations, of one or more mono- and/or diglycerides of fatty acids,(3) 0.1 up to 5% by weight, based on the total weight of the preparations, of one or more ethoxylated fatty acid esters,where the sum of (1), (2) and (3) is at most 12% by weight,(4) 0.5 to 10% by weight, based on the total weight of the preparations, of one or more nonpolar lipids,(5) 0.5-7.5% by weight, based on the total weight of the preparations, of one or more fatty alcohols(6) 0.5-7.5% by weight, based on the total weight of the preparations, of one or more lipophilic bodying agents having a melting point or dropping point of ≧30° C.,(7) 0.5 to 10% by weight, based on the total weight of the preparations, of hydrogenated polyisobutene having a molecular weight of from 100 to 4000 g/mol,(8) where the total lipid phase can comprise up to 40% by weight of polar lipids, based on the total weight of the lipid phase.
