Patent number: 7396417Abstract: A degreasing method for descaling or removing laser scales from iron-containing metal part surface by treating the iron-containing metal part surfaces that is optionally tainted with laser scales with an aqueous solution containing at least one type of highly water-soluble and complexed with Fe ions carboxylic acid, at least one type of salt of at least one type of carboxylic acid exhibiting the same action and at least one type of fatty amine ethoxylate, wherein the solution is buffered, the Fe ions are carried into the solution and at least partially complexed, increasing the pH value of the solution for descaling with respect to at least one type of carboxylic acid. The entire concentration of carboxylic acids and the salts thereof is increased for descaling by 2 to 20% by weight.Type: GrantFiled: September 20, 2005Date of Patent: July 8, 2008Assignee: Chemetall GmbHInventors: Peter Fischer, Hanspeter Brunner

Patent number: 7393818Abstract: A method of treating the surfaces of medical instruments which are contaminated with prions includes contacting the surface with a composition containing a source of peroxide ions, such as hydrogen peroxide, at a molar concentration of at least 1.5M peroxide (equivalent to approximately 5% hydrogen peroxide) and preferably, about 2M peroxide (approximately 7% hydrogen peroxide). The composition is optionally in the form of a gel. The composition is retained in contact with the surfaces for about 1-2 hours until all or substantially all prion contamination is removed.Type: GrantFiled: April 3, 2007Date of Patent: July 1, 2008Assignee: Steris Inc.Inventors: Gerald E. McDonnell, Herbert J. Kaiser, Kathleen M. Antloga, Mildred R. Bernardo

Publication number: 20080108537Abstract: A cleaning composition with a corrosion inhibitor system and an active halogen-based bleaching system and aqueous solution is described for inhibiting corrosion of metal surfaces to which the composition is applied, especially when the cleaning composition is not rinsed from the treated metal surface prior to drying of the composition on the metal surface. The corrosion inhibitor is at least an alkyl phosphonate compound, wherein the alkyl group has 6 or more carbon atoms, and salts thereof. The bleaching system includes one or more sources of hypohalous acid or hypohalite ion, such as a stabilized hypochlorite solution, in particular a mixture of N-chlorosulfamate salts.Type: ApplicationFiled: November 3, 2006Publication date: May 8, 2008Inventor: Wayne M. Rees

Patent number: 7307053Abstract: An improved combination air sanitizer, soft surface sanitizer, soft surface deodorizer and hard surface disinfectant is disclosed. The preferred active ingredient for the air sanitization and soft surface odor treatment functions is triethylene glycol (TEG). The preferred active ingredient for soft surface sanitization and hard surface disinfection functions is a mixture of various alkyl dimethyl benzyl ammonium saccharinates. The formulation may be provided in an aerosol spray form and is useful for sanitizing and removing bacteria and malodorant molecules from the air as well as disinfecting hard surfaces. A unique combination of corrosion inhibitors is disclosed for convention steel or tin-plated steel cans. A single produce can be used as an air sanitizer/air freshener, a soft surface sanitizer, a soft-surface odor remover/reducer and, a hard surface disinfectant.Type: GrantFiled: December 20, 2005Date of Patent: December 11, 2007Assignee: S.C. Johnson & Son, Inc.Inventors: Maciej K. Tasz, George J. Svoboda
