Cosmetic and dermatological preparations based on O/W emulsions

Abstract

Stable, biocompatible cosmetic or dermatological oil-in-water emulsions (I), containing fatty acids and alcohols, glycerides, ethoxylated esters, non-polar lipids and consistency components, are disclosed. Cosmetic or dermatological oil-in-water emulsion preparations (I) contain (by weight): (a) 0.1-5% 14-22C fatty acid(s); (b) 0.1-10% fatty acid mono- and/or diglyceride(s); (c) 0.1-5% ethoxylated fatty acid ester(s); (d) 0.5-10% non-polar lipid(s); (e) 0.5-7.5% fatty alcohol(s); and (f) 0.5-7.5% lipophilic consistency source(s) having a melting point or drop point of at least 30 degrees C. The sum of the contents of (a)-(c) is at most 12% by weight based on the total weight of the emulsion and the lipid phase optionally contains up to 40% by weight (based on this phase) of polar lipids.
