Abstract
An air treating composition for eliminating airborne malodors and/or sanitizing air in combination with a spray valve and actuator and spray performance parameters providing maximum dispersion of the composition is disclosed. The particles of the composition are small so that the active component is dispersed into air as a fine dispersion to provide more contact with malodors and to provide quick absorption of malodors and/or bacteria. The particle size of the composition is controlled through the valve and actuator dimensions, as well as the formulation requirements of the composition. The air treating composition includes water, a low molecular weight polyol, and a propellant. The composition may also include one or more adjuvants such as an emulsifier, a co-solvent, a fragrance, a corrosion inhibitor, a pH adjusting agent and the like.
