  • Patent number: 6682694
    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.

  • Publication number: 20040002436
    Abstract: Amine fabric softener actives are prepared in dispersion and/or clear form with materials to improve performance by increasing the cationic charge density. These materials include polycationic compounds, especially cationic polymers; single long-chain cationic compounds; and carboxylic acids that increase the acidity in the rinse, thus lowering pH and increasing the percentage of amine fabric softener active that is protonated. Antistatic properties are also improved.
