Abstract
An air treating composition for eliminating odors from air in combination with specific spray valve and actuator requirements and spray performance parameters providing maximum dispersion of the active component in the composition into the air 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 odors and to provide quick absorption of odors. The particle size of the composition is controlled through the selection of valve and actuator dimensions. The air treating and odor eliminating composition of the invention includes water, a low molecular weight polyol, an emulsifier, and a propellant. The composition may also include additional adjuvants such as solvent(s), fragrance(s), corrosion inhibitor, pH adjustor and the like.
