Abstract
An aerosol composition includes an admixture of: (a) at least one silicone-based fluid and (b) at least one fluorine-containing propellant that is soluble in the silicone-based fluid. In a preferred embodiment, the propellant includes a hydrofluorocarbon, in particular 1,1,1,2-tetrafluoroethane. An aerosol spray system includes: (a) a container; (b) the aerosol composition described above disposed within the container; (c) a metering device; and (d) a spray head. An aerosol lubricating composition includes the composition described above, wherein the silicone-based fluid is a lubricant. A method of lubricating, includes: (a) directing a container containing the lubricating composition described above at an article in need of lubrication; and (b) spraying the lubricating composition at the article. A flammable aerosol composition includes an aerosol composition which includes an admixture of: (a) at least one silicone-based fluid; and (b) at least one fluorine-containing propellant that is soluble in the silicone-based fluid, wherein the silicone-based fluid is a low viscosity silicone-based fluid. A spray system has improved spray characteristics for the aerosol composition by reducing the flow rate of the composition as it is being dispensed.
