  • Patent number: 7179485
    Abstract: This invention discloses, as an article of manufacture, a capsule having a hollow interior and an enclosing wall, referred to as a membrane. The membrane is not soluble in water, but is permeable to water or an aqueous solution. The membrane is comprised of a first material and can also include a second material. When the membrane is comprised of the first material and the second material, then it is referred to as a composite material wherein the first material forms sporting matrix having the second material fixed in the matrix. The first material is a urethane/vinyl hybrid polymer and is not soluble in, reactive with or a solvent for the second material. The second material is a particulate solid, different from the first material, and is not soluble in, reactive with or a solvent for the first material.

  • Patent number: 7141077
    Abstract: A process for wrinkleproofing cellulosic textiles comprises treating the textiles with a finish and drying the treated textiles, wherein the finish comprises one or more water-soluble or water-dispersible hydrophobically modified polyethyleneimines and/or polyvinylamines. Suitable hydrophobically modified polyethyleneimines are hydrophobically modified homopolymers of ethyleneimine, hydrophobically modified graft polymers of polyamidoamines or of polyvinylamines. Suitable hydrophobically modified polyvinylamines are hydrophobically modified at least partially hydrolyzed homo- or copolymers of N-vinylcarboxamides. The polyethyleneimines and polyvinylamines can be crosslinked by polyfunctional crosslinking compounds, quaternized and/or modified by reaction with alkylene oxides, dialkyl carbonates, alkylene carbonates and/or C1–C4-carboxylic acids.

  • Patent number: 7053034
    Abstract: The present invention relates to a novel controlled release carrier system for pH or salt triggered release and targeted delivery of fragrances and other active ingredients onto fabric, hair, skin, and other biological surfaces and which provides prolonged release of fragrances and other active ingredients over an extended period of time, or yields a high impact fragrance “burst” upon treating the target surface with heat (blow drying the hair, ironing the fabric). The controlled delivery system of the present invention is substantially a free-flowing powder formed of solid hydrophobic nano-spheres comprising the fragrance and other active ingredients that are encapsulated in a pH or salt sensitive micro-spheres. Also described are processes for preparing such compositions and processes for using same.

  • Patent number: 6221826
    Abstract: A laundry additive particle having multiple coatings and compositions employing the particle are provided. The laundry additive particle comprises a central core particle with the core particle comprising a porous carrier core material and a glassy encapsulating material intermixed with the carrier material. The glassy encapsulating material is derived from one or more at least partially water-soluble hydroxylic compounds having an anhydrous, nonplasticized, glass transition temperature, Tg, of at least about 0° C. An optional intermediate encapsulating material may be coated on the central core particle. The intermediate encapsulating material may comprise a carbohydrate material having an anhydrous nonplasticized, glass transition temperature, Tg of at least about 130° C. Lastly, an external coating material is coated on the core particle or the intermediate encapsulating material which provides the laundry additive particle with a substantially non-tacky surface.

  • Patent number: 6133224
    Abstract: Process for making a free-flowing, particulate dye transfer inhibiting detergent admix for inclusion in a granular laundry detergent composition consisting essentially of the steps of: charging from 50% to 95%, by weight of the dye transfer inhibiting detergent admix, of a detergent builder into a mixer/granulator; adding to the detergent builder from 5% to 50%, by weight of the dye transfer inhibiting detergent admix, of a dye transfer inhibitor solution to thereby form a mixture; and agglomerating the mixture of the dye transfer inhibitor solution and the detergent builder so as to form the dye transfer inhibiting detergent admix.

  • Patent number: 6099589
    Abstract: In fabric laundry procedures, commercial and household laundry detergent compositions commonly contain an optical brightener composition. Brighteners adjust the optical properties of the fabric in such a way that the fabric appears to be white even after repeated washings. Often white fabrics can yellow during use. Fluorescent optical brighteners having an optical blue aspect, mask the yellowing of the fabric. Common laundry detergents fail to have sufficient brightening capacity to brighten heavily soiled white cotton items used in household, commercial, institutional or fast-food food surface. A process for improving the whiteness of soiled white cotton, preferably terry cloth, items involves contacting the soiled white fabric item with a presoak containing an effective proportion of a fluorescent optical brightener composition, removing the item from the presoak and separating the presoak composition from the fabric item producing an extracted item.

  • 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.
