ABSTRACT:
A cosmetic or medical composition for topical application to the skin. It results in the transdermal passage of an active ingredient, or in the introduction of such agent into the skin. The essential components of such compositions are a phospholipid, a lower aliphatic alcohol of two to four carbon atoms, optionally with propylene glycol, water and a compatible active ingredient. The alcohol content is generally from 20 to 50%, and when propylene glycol is present, the combined percentage of alcohol and glycol being up to about 70%. The composition are suitable for the topical application of a wide variety of cosmetic and pharmaceutical compounds.
