  • Patent number: 6369021
    Abstract: The invention relates to a highly alkaline or mildly alkaline detergent composition having enhanced cleaning properties. The detergent combines a source of alkalinity and a blend of nonionic surfactants that enhances cleaning starchy soils. The blend of nonionic surfactants preferably includes an alkyl polyglycoside surfactant and a silicon surfactant having a hydrophobic silicon group and a pendant hydrophilic group. Preferably, the blend of nonionic surfactants includes a surfactant having a hydrophobic group and an ethylene oxide residue containing group and a polymer additive. A method for removing soil from an article is provided.

  • Patent number: 6302969
    Abstract: Basic cleaning compositions using toxicologically-acceptable ingredients for cleaning hard surfaces are provided. Compositions safe for use on surfaces which are contacted by food intended for ingestion by humans or lower animals, even when the compositions are incompletely removed from the cleansed surface, are described. Liquid formulations comprising surfactant, such as sodium alkyl sulfate, sodium alkylbenzene sulfonate, etc., and having a pH of above 11.6 are contacted directly onto hard surfaces to remove soil and unwanted deposits. Articles for applying the compositions to hard surfaces by spraying are disclosed.
