  • Patent number: 5804219
    Abstract: The present invention relates to compositions and processes which incorporate water-soluble polymers, other than enzymes, containing .dbd.N--C(.dbd.O)-- (including PVP) and/or N-oxide groups into the wash, rinse, and/or drying cycle of a laundering process (e.g., via fabric softening compositions) for dye transfer inhibition in the subsequent wash cycle. Multiple wash cycles optimize the dye transfer inhibitor performance of these polymers, remove unwanted dye discoloration caused by dye transfer, and provide soil antiredeposition benefits.

  • Patent number: 5783552
    Abstract: An effective amount of uncomplexed cyclodextrin, in the form of particles having particle sizes below about 12 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: 5747443
    Abstract: Fabric softening actives having hydrophobic moieties containing, preferably, ester, or amide, linkages and mixed branched and unsaturated hydrophobic groups provide improved processing and stability as well as surprisingly good softening. Preferred compositions contain mono-ol and diol principal solvents having a ClogP of from about 0.15 to about 0.64, that have the ability to make clear aqueous fabric softener compositions containing relatively high concentrations of the said fabric softener actives having ester linkages in their long, hydrophobic chains. Other solvents may be present. Premixes of the fabric softening actives, the principal solvents, and, optionally, other solvents are useful in the preparation of complete formulations by obviating/limiting the need for heating. Other compositions can be prepared which are solid or dispersions of the said fabric softening actives.

  • Patent number: 5707670
    Abstract: Nutritional iron compositions comprising bioavailable sources of iron selected from ferrous fumarate and ferrous succinate where the iron source is preferably spread on the surface of a lecithin coated edible carrier such as sucrose. These nutritional iron compositions are particularly useful in food and beverage products such as chocolate flavored edible mixes, especially chocolate flavored beverages, that are additionally fortified with other minerals and vitamins, especially multi-mineral and vitamin combinations involving, iodine, vitamin A, vitamin C, riboflavin, and folic acid to avoid developing an undesirable color, off-flavor, astringency, particularly when the edible and/or beverage mix is reconstituted with water or milk.
