Patent number: 5879469Abstract: A dishwashing method is dislosed wherein two detergent compositions, one being alkalinic and the other acidic are applied in sequence onto the dishes. The liquid compositions are applied onto the dishes directly without or with only a moderate dilution such that once applied onto the dishes they input respective alkalinic and acid pH's on the surface of the dishes.Type: GrantFiled: January 6, 1997Date of Patent: March 9, 1999Assignee: Deeay Technologies Ltd.Inventor: Nir Avram

Patent number: 5858946Abstract: There is provided a detergent composition comprising conventional detergent components characterized in that it contains a lactase enzyme. The lactase enzyme is preferably incorporated into the compositions at a level of from 0,0001% to 2% active enzyme by weight of the composition.Type: GrantFiled: February 4, 1997Date of Patent: January 12, 1999Assignee: Procter & Gamble CompanyInventors: Peter Robert Foley, Lynda Anne Jones

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.
