Patent number: 5612305Abstract: Machine dishwashing detergents are disclosed containing a compatible mixture of a low-foaming nonionic surfactant and a high-foaming nonionic surfactant. Dishes and other utensils are cleaned to a sparkling clean spot-free condition by the machine washing detergent composition of the present invention. The machine dishwashing detergent compositions of the present invention are effective especially in controlling foam encountered upon washing dishes and other utensils encrusted with soils generally encountered on dishes, specifically egg and milk-derived protein soils.Type: GrantFiled: January 12, 1995Date of Patent: March 18, 1997Assignee: Huntsman Petrochemical CorporationInventor: Ronald G.

Patent number: 5589099Abstract: 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.Type: GrantFiled: April 20, 1993Date of Patent: December 31, 1996Assignee: Ecolab Inc.Inventor: Burton M.
