  • Publication number: 20030162685
    Abstract: A solid cleaning composition comprises a source of active oxygen agent within a binder complex. The solid is formed by a binding agent that forms the ingredients into a solid. The binding agent is a composition formed by the solidification of a mixture of an organic sequestrant, including phosphonate or aminocarboxylic acid or mixtures thereof, an active oxygen compound, and water. The solid composition can be dissolved in an aqueous solution creating an aqueous concentrate of the active oxygen at a useful concentration. The binding agent can also be used to bind additional functional materials and form a solid cleaning composition comprising the source of stabilized active oxygen as well as the additional functional material.

  • Publication number: 20030087787
    Abstract: The present invention relates to a liquid enzyme cleaning composition in which the enzyme is stable at alkaline pH and: at high concentration of boric acid salt; in the absence of sodium ion; and/or in the presence of water at concentrations of at least about 60 weight percent. The present enzyme cleaning composition typically yields superior soil (especially protein soil) removal properties. In an embodiment, the composition of the invention stabilizes the enzyme with potassium and/or alkanolamine borate.

  • Patent number: 6257253
    Abstract: The invention includes compositions and methods for sanitizing ware without staining or spotting. In its most preferred mode, the method comprises the steps of washing the ware in an automated ware washing machine and rinsing the ware at either high or low temperatures with a sanitizing rinse composition. The destaining, sanitizing concentrate composition preferably comprises peroxy acetic acid, acetic acid, and hydrogen peroxide. The sanitizing rinse composition may preferably be used at a concentration ranging from about 600 ppm to 4000 ppm.
