Abstract:
1. A liquid aerosol composition for dispersing an active ingredient into air comprising (a) about 20 to about 70 wt. % of at least one hydrocarbon propellant; (b) about 0.001 to about 10 wt. % of at least one active ingredient; and (c) a solvent blend including wherein the total composition is equal to 100 wt. %, is essentially absent of water and is a single phase; wherein the composition as an aerosol has a particle size of less than 30 microns based on formulation of said composition and not by physical structure of an actuator by which the composition is dispensed; wherein each component of said solvent blend has a Hansen Solubility Parameter distance (Ra) between any two solvents where as (1) between each solvent of (i) and each solvent of (ii), the Ra is below 20, and (2) when said one or more coupling solvents are present, the difference between each solvent of (i) and each solvent of (ii) is a Ra either above or below 20, and then each solvent of (ii) and each solvent of (iii) have a difference in Ra below 20, and between each solvent of (i) and each solvent of (iii) the difference in Ra is below 20; and wherein the composition has an increased evaporation rate based on said solvent blend as compared to when said solvent blend is not present.
