Abstract
Perfluoroalkanes, including perfluorobutane, perfluoro propane and perfluoropentane are used in aerosol spray compositions contained within aerosol spray containers to act as propellants. Further, perfluoroalkanes are combined with sulphur hexafluoride for use as aerosol propellants. Specific examples, including insecticide formulations, are particularly set forth.
