  • Patent number: 5876514
    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.

  • Patent number: 5589099
    Abstract: Ethylene oxide/propylene oxide block copolymers having high cloud points, when compared to conventional rinse agent materials, have surprisingly been found to be useful in the manufacture of effective low foaming rinse aids. The rinse aids are prepared by combining the high cloud point copolymer with an effective defoamer and a water miscible diluent. The rinse aid composition can achieve adequate rinsing at common aqueous rinse temperatures at a concentration of the block copolymer in water less than 500 parts of the block copolymer per million parts of water. A liquid rinse agent concentrate can take the form of a low viscosity liquid, a thickened pourable or semi-pourable aqueous liquids. A solid rinse agent concentrate can be a cast solid material packaged within a soluble or disposable wrapper or capsule or other water soluble package. The rinse aids can be dispersed in a variety of ways by dilution with water to an aqueous final rinse composition.

  • 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.
