Patent number: 6622736Abstract: A water soluble glass is used in dishwashing machines as corrosion protection for glassware. The water soluble glass consists of at least one compound which, in the cleaning and/or rinsing cycles, releases an agent that protects glassware against corrosion. Each of the compounds accounts for no more than 85 molar % of the glass and the solubility of the water soluble glass is defined by a mass loss of at least 0.5 mm under the conditions specified in DIN ISO 719.Type: GrantFiled: August 15, 2001Date of Patent: September 23, 2003Assignee: Reckitt Benckiser N.V.Inventor: Karlheinz Hahn

Patent number: 6610645Abstract: A detergent composition containing an inexpensive detergent builder in the form of a selected crystalline calcium carbonate is provided. Specifically, the crystalline calcium carbonate has a substantially rhombohedral crystal structure with {1,0-1,1} crystallographic indices. The crystalline calcium carbonate can be calcite that has been specially modified to a rhombohedral crystal structure with {1,0-1,1} indices. The crystalline calcium carbonate of the present invention is extremely inexpensive because it can be readily formed from inexpensive naturally occurring calcite, and it performs well even when used at large median particle sizes.Type: GrantFiled: September 10, 1999Date of Patent: August 26, 2003Inventors: Eugene Joseph Pancheri, Robert Henry Rohrbaugh, Scott William Capeci, William Marion Hoffman, Rose Marie Weitzel

Publication number: 20030114329Abstract: The present invention is directed to a grease-cutting detergent composition that exhibits a stable foaming profile when used with non-enclosed automatic dishwashers. The composition can be sold in a concentrated form or in ready-to-use (RTU) diluted form. The concentrated compositions are formulated to be diluted with water before use. The RTU formulas are intended for as-is usage. In one embodiment the concentrated compositions comprises a) from about 0.25% to about 10% of a surfactant, b) from about 4% to about 8% of an alkalinity source, c) from about 0.1% to about 4.0% of a hydrotrope, d) from about 0.001% to about 2.0% of a builder, and e) from about 0.01% to about 3.0% of a thickener. In another embodiment an RTU formulation comprises a) from about 50 ppm to about 80 ppm of a surfactant, b) from about 45 ppm to about 75 ppm of an alkalinity source, c) from about 20 ppm to about 45 ppm of a hydrotrope, d) from about 0.Type: ApplicationFiled: September 16, 2002Publication date: June 19, 2003Inventors: Thomas James Wierenga, James August Weikel

Patent number: RE38262Abstract: 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.Type: GrantFiled: March 2, 2001Date of Patent: October 7, 2003Assignee: Ecolab Inc.Inventors: John J. Rolando, Terry J.
