Abstract
Abstract A single phase, liquid skin-conditioning formulation which can be discharged from an aerosol-type container by means of a halogenated alkane propellant is disclosed. The liquid formulation contains a non-soap, surface-active agent and the propellant dissolved in a solvent system comprising water and a lower-alkanol. When expelled from the pressurized container through a suitable nozzle, the composition forms a stable, nonsticky foam.
