A composition for solvating one or more active agents in an aqueous solution which is suitable for dispensing as a compressed gas aerosol composition is disclosed. The composition includes at least one surfactant, at least one active agent, and a compressed gas propellant. The at least one surfactant is preferably present in an amount from about 0.1 wt. % to about 3 wt. %. The at least one active agent is preferably present in an amount from about 0.1 wt. % to about 2 wt. %. The compressed gas propellant is preferably present in an amount from about 0.1 wt. % to about 1 wt. %. The total surfactant weight to active agent weight ratio for the composition is preferably about 1:3 to 5:1. The composition uses a reduced amount of surfactant and active agent thereby allowing for a more efficient active agent loading and a reduced stickiness or tackiness on surfaces contacted during use.

1. An aqueous composition pressurized with compressed gas containing at least one active agent comprising: (a) an active agent-based solution formed upon a combination of about 0.1 wt. % to about 3 wt. % of at least one surfactant and about 0.1 wt. % to about 2 wt. % of at least one water-insoluble
1. An aqueous composition pressurized with compressed gas containing at least one active agent comprising: (a) an active agent-based solution formed upon a combination of about 0.1 wt. % to about 3 wt. % of at least one surfactant and about 0.1 wt. % to about 2 wt. % of at least one water-insoluble or water-immiscible active agent, wherein said at least one surfactant is present in relation to said at least one water-insoluble or water-immiscible active agent in a ratio based on total surfactant weight % to active agent weight % of about 1:3 to 5:1,(b) about 0.1 wt. % to about 1 wt. % of a compressed gas propellant,(c) water, and(d) optionally at least one additive which is one or more of a preservative, a corrosion inhibitor, solvent, pH controller, an antimicrobial, processing aid, thickener, thioxotrope, and a dye;wherein said at least one water-insoluble or water-immiscible active agent is solvated into an aqueous active agent-based solution to provide a clear or substantially clear microemulsion. 2. The composition of claim 1, wherein said at least one water-insoluble or water-immiscible active agent is at least one of a fragrance, insecticide, medicament, repellant, germicide, sanitizer, or odor eliminator. 3. The composition of claim 1, wherein said at least one active agent is at least one fragrance. 4. The composition of claim 1, wherein said at least one active agent is at least one insecticide. 5. The composition of claim 1, wherein said at least one surfactant is one or more of an anionic, nonionic, cationic or amphoteric surfactant. 6. The composition of claim 1, wherein said at least one surfactant is a blend of nonionic and cationic surfactants. 7. The composition of claim 1, wherein said at least one surfactant is at least one of ethoxylated hydrogenated castor oil; ethoxylated hydrogenated castor oil blend; ethoxylated linear alcohol; secondary alcohol ethoxylate; polyglyceryl-10 laurate; polyglyceryl-6 caprylate; ethoxylated C6-C17 alcohol; sorbitan monooleate; polyoxyethylene sorbitan monooleate; polyoxyethylene sorbitan monolaurate; alkyl C9-C11 polyglycoside; didecyldimethyl-ammonium chloride; didecyldimethylammonium carbonate; polyethyleneoxide/polypropyleneoxide; and mixtures thereof. 8. The composition of claim 1, wherein said compressed gas propellant is at least one of air, nitrogen, nitrous oxide, argon, carbon dioxide, methane, ethane, and mixtures thereof. 9. The composition of claim 1, further comprising at least one corrosion inhibitor. 10. The composition of claim 9, wherein said at least one corrosion inhibitor is a phosphate, a nitrite, or amino methyl propanol. 11. The composition of claim 1, further comprising at least one solvent. 12. The composition of claim 11, wherein said at least one solvent is one or more alkylene glycol, or mixtures thereof. 13. The composition of claim 1, further comprising at least one antimicrobial. 14. The composition of claim 13, wherein said at least one antimicrobial is a methyl isothiazolone, a benzisothiazolone, a polyhexamethylene biguanide, a carbamate or mixtures thereof. 15. The composition of claim 1, wherein said water is present in an amount of about 90 wt. % to about 99 wt. %. 16. The composition of claim 1, wherein said ratio is 1:1 to 3:2.
