  • Method of laundering soiled fabrics by non-aqueous detergent formulated to control dye transfer and sudsing in high efficiency washing machines
    Patent number: 6348441
    Abstract: Disclosed is a method of laundering soiled fabrics comprising the steps of contacting said fabric in an aqueous laundering solution with a nonaqueous liquid detergent composition containing from about 40% to about 99% by weight of the composition of a surfactant-containing non-aqueous liquid phase and from about 1% to about 50% by weight of the composition of particulate material which is substantially insoluble in said liquid phase and which is selected from peroxygen bleaching agents, bleach activators, organic detergent builders, inorganic alkalinity sources and combinations thereof. A dye transfer inhibitor and suds suppressors are essential components in one aspect of the present invention.

  • Low sudsing granular detergent composition containing optimally selected levels of a foam control agent and enzymes
    Patent number: 6169063
    Abstract: A granular detergent composition is provided. The detergent composition comprises at least about 1% by weight of a surfactant and at least about 1% by weight of a builder. The detergent composition also includes from about 6 to about 9% of a particulate foam control agent. In addition, the detergent composition includes from about 0.1 to about 10% of hydrated magnesium sulfate, from about 0.05 to about 0.4% of a protease enzyme, and from about 0.05 to about 0.2% of a cellulase enzyme. The detergent composition produces the low level of foam required for optimal cleaning in washing machines employing a low water wash process.

  • Crystalline calcium carbonate builder enrobed with a hydrotrope for use in detergent compositions
    Patent number: 6130194
    Abstract: A detergent composition containing an inexpensive detergent builder in the form of a selected crystalline calcium carbonate that has been coated with a hydrotrope is provided. The crystalline calcium carbonate can be calcite and the hydrotrope can be xylene sulfonate. The crystalline calcium carbonate of the present invention is extremely inexpensive because it performs well even when used at large median particle sizes (e.g. less than 10 m.sup.2 /g surface areas).
