The foam formulation comprises an emulsion, which is oil in water emulsion and basically an emulsifying agent-free emulsion, i.e. the emulsion has an oil phase and a water phase. The oil phase has a membrane-forming substance, which is insoluble in water and forms a lamellar membrane in the foam formulation. The membrane-forming substance is a lipid, preferably 8-12 carbon triglyceride, and the lipid is a phospholipid, preferably lecithin, and a liquid wax ester. A thickening agent, a stabilizer, which has pentylene glycol, usual components and active ingredients are also provided. An independent claim is also included for a method for producing a foam formulation, which involves manufacturing an emulsion, preferably oil in water type, filling the emulsion and a foaming agent into a pressure-vessel or filling the emulsion into another pressure-vessel, which produces a foam by delivery of the emulsion. ACTIVITY : Dermatological. MECHANISM OF ACTION : None given.
