    Abstract: The inventors have discovered that partially halogenated hydantoins exhibit superior antimicrobial efficacy and decreased performance additive decomposition rates than fully halogenated hydantoins, such as dichlorodimethyl hydantoin (DCDMH). Partially halogenated hydantoins are solutions containing monochlorohydantoin and, optionally, dihalogenated hydantoin or non-halogenated hydantoin. The present invention is a method of reducing slime in a circulating water slurry comprising organic matter and one or more performance additives, such as optical brighteners, while minimizing decomposition of the performance additives. The method comprises adding one or more partially halogenated hydantoins, such as Cl1 1-chlorodimethyl hydantoin, to the slurry. The concentration of partially halogenated hydantoin maintained in the slurry generally ranges from about 0.01 to about 50 ppm (expressed as Cl2). This method is particularly useful for circulating water slurries in paper processing.

  • Patent number: 5843191
    Abstract: The present invention relates to the bleaching of fabrics with a hypochlorite-containing composition. The well-known prejudice against using hypochlorite bleaches to bleach synthetic fabrics because of the resulting fabric yellowing is addressed by the presence of silicate salts in the bleaching medium.

  • Patent number: 5834414
    Abstract: A novel detergent composition and product form provides for substantial chlorine stability in detergents having substantial organic surfactant concentration. The product format ensures that water contained in the formulation, contact between sensitive organic materials and the chlorine source are structurally isolated preventing undesirable chlorine surfactant interactions and instability. Particulate detergents can be packaged in any arbitrary packaging component that can maintain a dry flowable powder.

  • Patent number: 5804543
    Abstract: Disclosed are detergent compositions and methods which are suitable for washing colored fabrics in aqueous washing solution with little or no transfer of dye between fabrics. The compositions utilized comprise certain nil-LAS detersive surfactants, detergent builder and certain selected polymeric dye transfer inhibiting agents. The detersive surfactants used must comprise alkyl ether sulfates and certain types of nonionic surfactants (polyhydroxy fatty acid amides and/or alcohol ethoxylates). The polymeric dye transfer inhibiting agents are polyamine N-oxides such as poly(4-vinylpyridine-N-oxide), i.e., PVNO and/or copolymers of N-vinylpyrrolidone and N-vinylimidazole, i.e., PVPVI.

  • Patent number: 5776878
    Abstract: Compositions for reducing brightener spotting comprise a polymer selected from the group consisting of polyamine N-oxide containing polymers, N-vinylimidazole N-vinylpyrrolidone copolymers and mixtures thereof, a stilbene brightener, and from 5% to 7% hydrogen peroxide, wherein the weight ratio of the polymer to the brightener is from 1:20 to 20:1 and the pH of the composition is from 2 to 6.

  • Patent number: 5773399
    Abstract: Granular laundry detergents are formulated with percarbonate bleach and oxidation-sensitive ingredients such as brighteners, enzymes, perfumes and the like. The storage stability of such compositions is improved by the presence of silicate. For example, the tendency of stilbene-type brighteners to form undesirable yellow shades in the presence of percarbonate is diminished by the corporation of silicate materials into the granules.

  • Patent number: 5698508
    Abstract: A powdered detergent composition comprising a nonionic surfactant as the main surfactant, which comprises (a) a polyoxyethylene alkyl ether, wherein the alkyl group has 10 to 20 carbon atoms on the average and the average molar number of ethylene oxide added is 5 to 15, in an amount of 12 to 35% by weight based on the total weight of the composition, (b) a lipolytic enzyme in such an amount that the lipolytic activity per gram of component (a) would be 0.1 to 500 LU, (c) an anionic surfactant in an amount of 1.0 to 7.0% by weight based on the total weight of the composition and (d) an alkaline material in an amount of 5 to 35% by weight based on the total weight of the composition, and of which a 0.1% by weight aqueous solution has a pH exceeding 9.0, is excellent in detergency on oily soils such as subum soil.
