Claim:
A solid dermatological composition comprising a biologically active agent dissolved in a homogeneous carrier system, wherein the carrier system consists essentially of: (a) 20–85% by weight of a solvent comprising (i) an unsaturated C 16 –C 20 -fatty acid alcohol selected from one or more of oleyl alcohol, ricinolyl alcohol, linolyl alcohol, linoleyl alcohol, eleosteryl alcohol, palmitoleyl alcohol, or arachidonyl alcohol in combination with (ii) an alkylene glycol selected from one or more of propylene glycol or dipropylene glycol, said alkylene glycol being present in the solvent in an amount of more than 12% by weight to provide for mutual dissolution of the unsaturated C 16 –C 20 -fatty acid alcohol and the active agent; and (b) 15–80% of a viscosity enhancing agent that is a waxy substance for imparting a solid consistency to the composition; all percentages in (a) and (b) being based on the total weight of the homogeneous carrier system.
