Patent number: 6630434Abstract: A low viscosity aqueous cleaning composition provides increasing viscosity upon dilution which provides a high viscosity diluted cleaning composition having solvents compatible with the rod micelle thickener and the cleaning system that clings for an extended period of time in a thickened form containing cleaning system ingredients that can penetrate and remove hard baked-on soils on vertical surfaces in cleaning units. The composition contains active cleaning ingredients (acid, alkaline and enzyme) that, in combination with thickening systems, provide the useful properties. The thickened materials can be applied on cold or hot surfaces and can successfully penetrate, soften and remove baked-on food soil on a variety of surfaces including oven walls, doors and grills, baking dishes, utensils, etc.Type: GrantFiled: May 21, 2001Date of Patent: October 7, 2003Assignee: Ecolab Inc.Inventors: Michael E. Besse, Richard O. Ruhr, Gerald K. Wichmann, Timothy A. Gutzmann

Patent number: 6554005Abstract: A method for cleaning polyethylene terephthalate containers including contacting the PET container with an alkaline wash solution having a temperature ranging of less than about 60° C. is disclosed. The alkaline wash solution is formulated from a first concentrate, a second concentrate, an alkalinity source, and a balance of water. The first concentrate preferably has a first nonionic surfactant, a first builder, and acid in an amount effective to provide a phase stable solution. The second concentrate preferably has a second nonionic surfactant and a second builder. The first and second concentrate are present in the wash solution in a concentration ranging from about 0.3 wt. % to 2.0 wt. %. Preferably, the first nonionic surfactant has a cloud point ranging from about 5° C. to 60° C.Type: GrantFiled: September 25, 2000Date of Patent: April 29, 2003Assignee: Ecolab Inc.Inventors: Bruce R. Cords, Gerald K. Wichmann, Guang-Jong Jason Wei, David D. McSherry, Brandon L. Herdt, Arturo Valencia
