Abstract

The invention relates to an anhydrous cosmetic or dermatological formulation comprising a viscose lipid-containing preparation and propellant gas consisting essentially of one or more substances selected from hydrofluorocarbons, n-butane, isobutane and propane. The formulation permits application to the skin by spraying of an otherwise nonsprayable preparation. The formulation is free from readily volatile solvents, surfactants, and preferably free from silicones.
