  • Patent number: 6235697
    Abstract: A laundry detergent composition is provided for enhanced whitening and stain removal of washed laundry comprising: a) from about 1% to about 50%, by weight, of a surfactant or surfactant mixture selected from the group consisting of anionic and nonionic surfactants; b) a protease enzyme in an amount sufficient to provide from at least about 0.030 to about 3.0 Kilo Novo Protease Units (KNPU) of activity of protease enzyme per gram of detergent composition; c) a cellulase enzyme of the endoglucanase type in an amount sufficient to provide from about 0.5 to about 100 CMC units per gram of detergent composition; and d) from about 0.5% to about 10% by weight, of an acrylic acid-based polymer and copolymer.

  • Patent number: 5866525
    Abstract: A particulate laundry detergent composition is provided having significantly improved oily soil removal activity. The composition comprises (a) from about 1 to 50%, by weight, of one or more detergent compounds selected from the group consisting of anionic and nonionic detergent compounds, and particularly alkyl polyglucoside and poly hydroxy fatty acid amide detergents; (b) a lipase enzyme in an amount effective for oily soil removal from stained fabric; and (c) a soil release polymer in an amount effective for oily soil removal from stained fabric. The laundry detergent compositions is characterized by its ability to remove a variety of oily soils from fabric to an extent greater than the additive soil removing effects measured with comparative compositions containing components (a) and (b), and components (a) and (c), respectively.
