Patent ID: 7226579

Claim:
A single phase propellant-concentrate aerosol composition for use in the spray application of an active ingredient from a pressurized container, consisting essentially of a first component (a) and a second component (b), wherein: component (a) is a concentrate of 10 to 60 wt % of component (a) and component (b), the concentrate consisting essentially of (i) an oil ingredient of 30 to 90 wt % of component (a), (ii) polyol of 5 to 50 wt % of component (a), (iii) water of 1 to 30 wt % of component (a), and (iv) the active ingredient of 0.1 to 20 wt % of component (a); and component (b) is a dimethyl ether propellant of 90 to 40 wt % of component (a) and component (b); wherein the component (a) does not have a flash point under 1 atmosphere of pressure, wherein the oil ingredient is selected from the group consisting of hydrocarbon, silicone, ester oil and the mixture, and the oil ingredient (1) is liquid under room temperature, (2) has a carbon number of 10 or more, and (3) has a flash point of 60° C. or higher, wherein the polyol has a flash point of 100° C. or higher, and wherein, when said aerosol composition is sprayed into the air from the pressurized container, said component (b) vaporizes in the air and said component (a) separates in the air into a hydrophilic liquid combination of polyol and water and an oleophilic liquid combination of the active ingredient and the oil ingredient.
