United States Patent:  5,935,554

Inventors:  Tomlinson; Roderick Peter John (Rowville, AU)

Appl. No.:  835583

A dispenser for space spraying an aerosol composition comprising a container for containing the aerosol composition and a metering device for space spraying a metered amount of he composition. The composition comprises active ingredient and propellant wherein the propellant is dissolved in the active ingredient. In preferred form, the composition comprises a non-aqueous solution containing 10-85% w/w active ingredient, 1-25% w/w co-solvent and 15-80% w/w propellant.

Summary of the Invention

Accordingly, the present invention provides means, including an improved aerosol space spray, for ameliorating at least some of the disadvantages of the prior art.

More particularly, the present invention provides an improved aerosol space spray which requires less release of undesirable VOC's into the environment while still providing adequate dispersal of the active ingredient in the atmosphere. Most desirably, the present invention provides a space spray composition and container that substantially reduce the amount of VOC's required in, and released in each use by, an aerosol space spray.

To this end there is provided an aerosol composition for space spraying comprising a solution of at least one active ingredient and a propellant (and, optionally, solvent and one or more adjuvants), a substantial portion of said propellant being dissolved in said active ingredient.

In preferred form, there is provided an aerosol composition for space spraying comprising a solution of at least one active ingredient and propellant, a substantial portion of said propellant being dissolved in said active ingredient. Another preferred embodiment further comprises co-solvent, said propellant being dissolved in said active ingredient and cosolvent.

Claim 1 of 26 Claims

1. A stable, liquid aerosol composition that is not an emulsion and that is effective as a space spray consisting essentially of about 10 to about 90% by weight of at least one active ingredient selected from the grour consisting of insecticides, perfumes, antimicrobial agents and mixtures thereof and about 90 to about 10% by weight of propellant, wherein the active ingredient is different from the propellant and wherein a substantial portion of said propellant is dissolved in said active ingredient.
