  • Patent number: 8980818
    Abstract: The present invention relates to an aqueous composition comprising three components. The first component is a primary detergent, non-ionic surfactant with a critical packing parameters (CPP) of ?0.95. The second component is a inorganic particle whose surface has been modified to improve stability. The third necessary component is a secondary surfactant with a CPP of ?0.85. The secondary surfactant can function to improve the overall cleaning performance, the streaking performance and provide overall formulation stability.

  • Patent number: 6727213
    Abstract: A composition for use in a dishwasher is characterized by a base composition in the form of a tablet which becomes active substantially during the main wash cycle of the dishwasher. At least one separate zone in or on the tablet is provided with a substance that becomes active substantially during the rinse cycle of the dishwasher and with at least one substance that prevents lime scale build-up in the dishwasher and/or on the washed articles. The composition further includes agents that guarantee that at least the substance that becomes active substantially during the rinse cycle of the dishwasher is at least mainly released at the beginning of the rinse cycle at the earliest.

  • Patent number: 6649586
    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: 6448210
    Abstract: A liquid dishwashing detergent composition having improved glassware protection when employed in conjunction with cleaning materials having high concentrations of alkaline materials. The composition contains a soluble organic zinc compound which preferably is zinc gluconate and is particularly suited to fast cycle commercial (I&I) dishwashers. The zinc gluconate is prepared in situ or zinc and gluconic ions are provided in a batching process.

  • Patent number: 6372702
    Abstract: A dishwashing composition having a silicon comprising surfactant, a dialkyl ester of an alpha, omega-alkyl dicarboxylic acid surfactant or both is described. The dishwashing composition unexpectedly results in dishware that does display improved starch soil removal and does not display starch buildup after multiple washes.

  • Patent number: RE38262
    Abstract: We have found an alkaline warewashing detergent composition that can contain a critical amount of a nonionic rinse agent that when used in automatic warewashing machines permits the use of a potable water rinse without the addition of a separate rinse agent. Sufficient residual nonionic surfactant from the alkaline detergent remains on the surface ware and internal machine and rack surfaces after washing to promote adequate sheeting in the rinse cycle. The residual nonionic surfactant on internal surfaces dissolves in the rinse water to create an effective aqueous rinse agent. The nonionic rinse agents can be a single nonionic for both foam reduction cleaning and sheeting or can be a blend of nonionic materials providing these functions. The detergent can be in the form of a particulate, pelletized or block solid.
