Abstract
The present invention relates to a stable, aqueous odor-absorbing solution, for use on inanimate surfaces. The solution comprises from about 0.1% to about 5%, by weight of the solution, of solubilized, water-soluble, uncomplexed cyclodextrin, an effective amount of a solubilized, water-soluble, antimicrobial preservative having a water-solubility of greater than about 0.3%, optional perfume, and an aqueous carrier. The solution is essentially free of any material that would soil or stain fabric and has a pH of greater than about 3. The solution can be incorporated into a spray dispenser to create an article of commerce that can facilitate treatment of articles and/or surfaces with uncomplexed cyclodextrin solutions of a level that is effective yet is not discernible when dried on the surface.
