  • Patent number: 6432906
    Abstract: A stable, substantially homogeneous, solid block cleaning composition can be made for general purpose cleaning and for cleaning hard surfaces such as floors of varying surface composition. Unique solid block materials contain substantially useful concentrations of liquid acid materials, but are in the form of a stable solid. The acidic solid detergent can be dispensed using a water spray creating a concentrate which can then be diluted in proper ratio to form the use-solution. Such use-solutions may be applied to remove a variety of soils subject to acid cleaning including soils containing water hardness components, inorganic soils, and the like. The acid cleaners can be used alone or in combination with other cleaners in a cleaning protocol for a variety of hospitality, industrial or institutional cleaning locations having a broad spectrum of contaminated soil residue.

  • Patent number: 6417155
    Abstract: Colored detergent bars are provided comprising water soluble polymeric colorants that exhibit excellent non-staining performance on fabrics and other contacted surfaces, including manufacturing and/or washing equipment, are easy to process into the desired detergent bar compositions, and do not exhibit any appreciable harmful effects to the environment. The particular polymeric colorants utilized in this respect are of very high molecular weight (in order to assure staining will not occur on target cleaning surfaces), are extremely water soluble, provide excellent vivid and aesthetically pleasing color shades within the target bar compositions, and are present as liquid or waxy pastes at room and at processing temperatures. The ultimate laundry bar product thus exhibits highly pleasing colors for product distinction as well as for aesthetic purposes.
