  • Patent number: 5997759
    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 20%, by weight of the composition, of solubilized, water-soluble, uncomplexed cyclodextrin and an effective amount of at least one ingredient to improve the performance of the composition selected from the group consisting of: (1) cyclodextrin compatible surfactant; (2) cyclodextrin compatible antimicrobial active; and (3) mixtures thereof. Hydrophilic perfume improves acceptance. Optionally, the composition can contain low molecular weight polyols; metallic salts to help control odor; a humectant, etc. The composition is 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, preferably non-manually operated sprayers.

  • Patent number: 5968404
    Abstract: The present invention relates to a stable, aqueous odor-absorbing and wrinkle controlling composition, preferably for use on inanimate surfaces, especially fabrics. The composition comprises from about 0.1% to about 20%, by weight of the composition, of solubilized, water-soluble, uncomplexed cyclodextrin and an effective amount of at least one ingredient to improve the performance of the composition selected from the group consisting of: (1) cyclodextrin compatible surfactant; (2) cyclodextrin compatible antimicrobial active; and (3) mixtures thereof. The composition also comprises a wrinkle control agent which is fabric lubricant, shape retention polymer, hydrophilic plasticizer, lithium salt, or mixtures thereof. Hydrophilic perfume improves acceptance. Optionally, the composition can contain low molecular weight polyols; metallic salts to help control odor; a humectant, etc. The composition is essentially free of any material that would soil or stain fabric.

  • Patent number: 5849310
    Abstract: Personal treatment compositions including cleansing and/or cosmetic compositions are disclosed, the cleansing compositions, for example, comprising from about 0.001% to about 10%, preferably from about 0.005% to about 6%, enduring perfume comprising at least about 70% of enduring perfume ingredients; from about 0.01% to about 95% surfactant system; and the balance carrier. The enduring perfume provides a lasting olfactory sensation thus minimizing the need to use large amounts. Preferred compositions are liquid and comprise water as a carrier.

  • 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.
