Claim:
A composition comprising a first part comprising a non-aqueous solvent, a first non-chlorine aerosol propellant, an emulsifying agent, a thickening agent, at least one medicament and optionally an aqueous solvent; and a second part comprising a second non-chlorine aerosol propellant that has a higher pressure than the first non-chlorine aerosol propellant, wherein the second non-chlorine aerosol propellant comprises 1,1,1,2-tetrafluoroethane and has a pressure of about 80 to 100 psig; wherein the first part is separated from the second part and the second part exerts pressure on the first part such that the first non-chlorine aerosol propellant is maintained as a liquid and the first part is a homogenous liquid; and wherein the first part is in the form of a liquid, foam, film or gel when exposed to atmospheric pressure.
