  • Mixed gas method for filling aerosol containers and aerosol formulas for improved environmental profile by VOC/HFC reduction
    Patent number: 8191739
    Abstract: An aerosol dispenser that is pressurized by both compressed gas and liquefied gas is able to retain desired spray characteristics, such as foaming, while reducing volatile organic compound content or hydrofluorocarbon content. A minimal amount of liquefied gas allows the product to retain its desired spray characteristics, and the compressed gas causes higher internal pressures while reducing the amount of liquefied gas needed as a propellant. The aerosol container may be filled by first placing a desired aerosol product in the container, followed by introducing liquefied gas followed by compressed gas, or by introducing compressed gas followed by liquefied gas.
