Abstract
The present invention relates to a stable, aqueous odor-absorbing composition, preferably for use on inanimate surfaces. The composition comprises from about 0.1% to about 0.5%, by weight of the composition, of an emulsion or dispersion comprising long lasting hydrophobic perfume to improve acceptance. Optionally, the composition can contain low molecular weight polyols; metallic salts to help control odor; water soluble anionic polymer to help control odor; a humectant, etc. The composition is preferably essentially free of any material that would soil or stain fabric. The composition is preferably applied as small particle size droplets, especially from spray containers.
