  • Patent number: 5681806
    Abstract: An effective amount of uncomplexed cyclodextrin, in the form of particles having particle sizes below about 5 microns, is incorporated into solid dryer-activated fabric conditioning compositions which are used in dryers to treat fabrics. The cyclodextrin is thereby attached to the fabrics and subsequently provides effective control of odors when they come in contact with the treated fabric. The fabric conditioning compositions can be attached to substrates to prepare an article of manufacture or be in the form of detergent compatible particles, for use with conventional laundry detergents.

  • Patent number: 5668097
    Abstract: The present invention relates to a stable, aqueous odor-absorbing composition, for use on inanimate surfaces. The composition comprises from about 0.1% to about 5%, by weight of the composition, 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 composition is essentially free of any material that would soil or stain fabric and has a pH of greater than about 3. The composition 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.

  • Patent number: 5660845
    Abstract: An effective amount of active/cyclodextrin complex, in the form of particles having particle sizes below about 12 microns, is incorporated into solid consumer product compositions. The complexes provide fast release of the active when they are wetted even when the amount of water available to effect release of the active is limited as in personal use compositions like drugs, foods, and cosmetics where active release is typically effected by body fluids. Preferred actives include perfumes, flavors, and pharmaceutical materials that are used by consumers.

  • Patent number: 5652206
    Abstract: The present invention relates to liquid and solid biodegradable fabric softener compositions combined with highly enduring substantive perfume compositions. These enduring perfume compositions comprise at least about 70% of enduring perfume ingredients. These compositions provide better perfume deposition on treated fabric, and consequently are not substantially lost during the rinse and drying cycle for less impact on the environment. Also, these perfumes improve the physical stability of the softener composition.
