  • Patent number: 6593289
    Abstract: Fabric softener compositions comprising certain red colorants that exhibit excellent deep, dark red colorations (for aesthetic purposes) and mix very well with other colorants to provide differing red shades and tints therein, which simultaneously exhibit very low, if any staining capabilities on fabrics treated therewith, are provided. Such deep and dark red colorations have heretofore been unavailable within fabric softener formulations due to the tendency of such prior colorants to exhibit unacceptable staining levels, particularly when formulated at similar deep and dark shades as now provided within the inventive low-staining formulations. Apparently, and quite unexpectedly, the colorants present therein react favorably with quaternary ammonium salt softening agents in a manner to prevent reaction with the fibers of the treated fabrics themselves, thereby preventing staining thereon and therein.

Such complexes are formed through ionic bonds formed between the two compounds. The inventive complexes are then removed of substantially all excess unwanted salt so as to obtain an optical brightener compound which easily solubilizes within, dispenses from, and exhibits excellent compatibility with standard detergent and softener compositions, which exhibits the desired degree of affinity for various substrate surfaces, including textile, paper, wood, and plastics, as well as within leak detector formulations, and which provides a desired accumulation effect on substrate surfaces upon repeated treatments. Such inventive complexes can also be utilized to whiten thermoplastics and thermosets. Furthermore, this invention also concerns methods of making and utilizing such inventive optical brightening complexes.

  • 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: 5767062
    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.
