Aerosol propellant compositions

Abstract

The present invention concerns new propellant compositions for aerosols. More particularly, the present invention relates to propellant compositions for aerosols, characterized in that said compositions consist of a mixture of a chlorofluorocarbon or fluorocarbon (A) containing hydrogen and selected from the group consisting of CHClF.sub.2, CH.sub.2 F.sub.2 and CF.sub.3 --CH.sub.3, with a chlorofluorocarbon or fluorocarbon (B) containing hydrogen and selected from the group consisting of: CH.sub.2 ClF, CClF.sub.2 --CHClF, CF.sub.3 --CHClF, CHF.sub.2 --CClF.sub.2, CHClF--CHF.sub.2, CF.sub.3 --CH.sub.2 --Cl, CHF.sub.2 --CHF.sub.2, CF.sub.3 --CH.sub.2 F, CClF.sub.2 --CH.sub.3 and CHF.sub.2 --CH.sub.3. In addition to propellant A and propellant B, there may be included a hydrocarbon propellant so that a ternary propellant composition is provided.
