Abstract
Certain surfactants suitable for use alone to dissolve a water-insoluble component in compositions is described for providing VOC-free compressed gas aerosol compositions. The compositions include water-insoluble component(s), a surfactant and water. The water-insoluble component(s) can be active agent(s), such as fragrance(s) and/or an insecticide(s). The surfactant is present as a single surfactant which, in the absence of a solvent, dissolves or disperses the water-insoluble component(s) and provides a homogenous blend in water which provides a stable compressed gas emulsion. The surfactant is an anionic surfactant or a nonionic surfactant, in particular nonionic alkylpolyglycosides; nonionic cocoglucoside; nonionic alkylene oxide extended chain alkylpolyglycosides; anionic sodium lauryl ether sulfate (SLES), nonionic C13-C15 oxoalcohol ethoxylate with 8 ethylene oxides (EO), nonionic C12-C14 secondary alcohol ethoxylate with 7EO or 12EO, polyethylene glycol (PEG) hydrogenated castor oil wherein the PEG is PEG-60 or PEG-40, polyglyceryl-10 laurate and polyglyceryl-6 caprylate.
