The amount of gaseous flammable propellants such as dimethylether, difluoroethane, propane, butane, and the like can be increased to as high as from 30 to 50% by weight of a propellant composition by dissolving the normally gaseous propellant in the dispersed oil phase of an oil-in-water microemulsion. The aerosol propellant compositions can be simply prepared by metering the ingredients other than the gaseous propellants into an aerosol dispenser, then adding the gaseous propellant, under suitable pressure, into the aerosol dispenser whereby simply shaking of the dispenser will result in the spontaneous formation of an oil-in-water microemulsion which is clear and stable and which can contain as much as about 50% by weight of the gaseous propellant without causing flaming when the composition is sprayed directly into a candle flame.

The amount of gaseous flammable propellants such as dimethylether, difluoroethane, propane, butane, and the like can be increased to as high as from 30 to 50% by weight of a propellant composition by dissolving the normally gaseous propellant in the dispersed oil phase or an oil-in-water microemulsion. The aerosol propellant compositions can be simply prepared by admixing into a container, pressurizing the container with the normally gaseous flammable propellant whereby simply shaking would result in the spontaneous formation of an oil-in-water microemulsion which is clear and stable and which can contain as much as about 50% by weight of the gaseous propellant without causing flaming when the composition is sprayed directly into a candle flame. The composition may be transferred from the container to aerosol dispensers.
