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.

Abstract: Pesticide concentrates are provided containing an emulsifier that is an EPA list 4 inert and is a polyglycerol fatty acid ester, a sorbitan fatty acid ester or a combination thereof, a pesticide and a solvent that is either a EPA list 3 inert of acetyl ester, EPA list 4 inert of a methyl fatty ester, an acetyltributyl citrate, white mineral oil or a combination thereof. The pesticide can be a water-insoluble synthetic pyrethroid, natural pyrethrum, channel blocking insecticide, acetylcholinesterase inhibitor, oxadiazine, organophosphate, neonicotinoid insecticide, thiamethoxam, imidacloprid, acetamiprid, thiacloprid, clothianidin, nitenpyran, insect growth regulator, juvenile hormone mimic, fermentation insecticide, plant oil insecticide acaracide, miticide, fungicide, herbicide and combinations thereof. The pesticide concentrate is diluted with a hydrocarbon solvent, a white mineral oil or a combination thereof and mixed with water.
