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.

1. An aerosol product comprising: one or more aerosol formula concentrates;a liquefied gas with a vapor pressure;a compressed gas insoluble in the one or more aerosol formula concentrates and the liquefied gas; anda container;wherein the compressed gas and liquefied gas together provide an internal pressure to the aerosol product inside the container that is more than respectively each of the individual pressure of the compressed gas and the individual vapor pressure of the liquefied gas. 2. A foaming aerosol product comprising: one or more water-based aerosol formula concentrates;a liquefied gas insoluble in water with a vapor pressure;a compressed gas insoluble in the one or more aerosol formula concentrates and the liquefied gas; anda container;wherein the compressed gas and liquefied gas add internal pressure to the foaming aerosol product inside the container;wherein the internal pressure of the foaming aerosol product is more than the respective individual pressure of each of the pressure of the compressed gas and the vapor pressure of the liquefied gas. 3. The foaming aerosol product of claim 2 wherein the one or more aerosol formula concentrates are selected from the group consisting of glass cleaner, general purpose cleaner, stainless steel polish, dust mop treatment, and furniture polish. 4. The foaming aerosol product of claim 2 wherein the liquefied gas is selected from the group consisting of one or more LPGs, one or more HFCs, and a blend of one or more LPGs with one or more HFCs. 5. The foaming aerosol product of claim 2 wherein the one or more aerosol formula concentrates are selected from the group consisting of glass cleaner, general purpose cleaner, stainless steel polish, dust mop treatment, and furniture polish; the liquefied gas is selected from the group consisting of A-17, A-31, A-46, A-70, 134a, and 152a; andthe compressed gas is nitrogen, at a pressure of about 20 psig to about 170 psig. 6. A method of filling an aerosol container comprising: introducing an amount of one or more aerosol formula concentrates into an aerosol container;introducing an amount of liquefied gas into the aerosol container; andintroducing an amount of compressed gas into the aerosol container after introducing the amount of one or more aerosol formula concentrates and before introducing the amount of liquefied gas, wherein the compressed gas is insoluble in the amount of one or more aerosol formula concentrates. 7. The method of filling an aerosol container of claim 6 wherein the said amount of one or more aerosol formula concentrates includes a water-based concentrate. 8. The method of filling an aerosol container of claim 6, wherein the one or more aerosol formula concentrates are one or more foaming aerosol formula concentrates. 9. The method of filling an aerosol container of claim 8 further comprising clinching an aerosol valve onto the aerosol container prior to introducing both the amount of liquefied gas into the aerosol container and the amount of compressed gas into the aerosol container. 10. The method of filling an aerosol container of claim 8 further comprising clinching an aerosol valve onto the aerosol container after the introduction of the amount of compressed gas into the aerosol container and prior to introduction of the amount of liquefied gas into the aerosol container. 11. The method of filling an aerosol container of claim 6 further comprising clinching an aerosol valve onto the aerosol container prior to introduction of the amount of liquefied gas into the aerosol container and after introduction of the amount of compressed gas into the aerosol container. 12. The method of filling an aerosol container of claim 6 further comprising clinching an aerosol valve onto the aerosol container prior to introducing both the amount of liquefied gas and the amount of compressed gas into the aerosol container. 13. The method of filling an aerosol container of claim 12 wherein the one or more aerosol formula concentrates are selected from the group consisting of glass cleaner, general purpose cleaner, stainless steel polish, dust mop treatment, and furniture polish. 14. The method of filling an aerosol container of claim 12 wherein the liquefied gas is selected from the group consisting of one or more LPGs, one or more HFCs, and a blend of one or more LPGs with one or more HFCs. 15. The method of filling an aerosol container of claim 12 wherein the one or more aerosol formula concentrates are selected from the group consisting of glass cleaner, general purpose cleaner, stainless steel polish, dust mop treatment, and furniture polish; the compressed gas is nitrogen, at a pressure of about 20 psig to about 170 psig; and the liquefied gas is selected from the group consisting of A-17, A-31, A-46, A-70, 134a, and 152a. 16. The method of filling an aerosol container of claim 6 wherein the amount of liquefied gas introduced into the aerosol container after introducing the amount of compressed gas is from approximately 2% up to approximately 5% by weight of total product weight in the aerosol container. 17. The method of filling an aerosol container of claim 16 wherein the one or more aerosol formula concentrates are selected from the group consisting of glass cleaner, general purpose cleaner, stainless steel polish, dust mop treatment, and furniture polish. 18. The method of filling an aerosol container of claim 16 wherein the liquefied gas is selected from the group consisting of one or more LPGs, one or more HFCs, and a blend of one or more LPGs with one or more HFCs. 19. The method of filling an aerosol container of claim 16 wherein the one or more aerosol formula concentrates are selected from the group consisting of the following products: glass cleaner, general purpose cleaner, stainless steel polish, dust mop treatment, and furniture polish; the compressed gas is nitrogen, at a pressure of about 20 psig to about 170 psig; and the liquefied gas is selected from the group consisting of A-17, A-31, A-46, A-70, 134a, and 152a.
