Patent number: 9029311Abstract: This invention relates to extend the benefits of using hypochlorite compounds such as sodium hypochlorite to clean and disinfect articles while reducing or eliminating the side effects of treating an article with a strong oxidant material. The invention relates to a single step process involving mixing of precursor compositions of a suitable hypohalite or hypohalous acid with a solution of a reducing agent. Optionally a buffer may be present in either or both precursor compositions, such that at time of use such active hypohalous acid concentration in the resulting aqueous mixture remains at a sufficient activity level to effect one or more desired benefits against a target substrate for a desired period of time. The oxidant is substantially consumed by reaction with the reducing agent after the time needed for achieving the desired benefit has passed.Type: GrantFiled: November 9, 2012Date of Patent: May 12, 2015Assignee: The Clorox CompanyInventors: Dewain Garner, William Smith, Jared Heymann

Patent number: 8349788Abstract: This invention discovers that laundry-strength hypochlorite bleach compositions are described by three essential components; hypochlorite, hydroxide, and the concentration ratio (CR), the latter defined as the concentration of hypochlorite over the concentration of hydroxide (also, its reciprocal). The hypochlorite content determines fabric cleaning efficacy, the hydroxide content determines stability, and the CR indicates quality of fabric safety, such quality ranging from damaging to gentle. Therefore, hypochlorite bleach compositions can range from fabric damaging to degrees of fabric protection, depending upon the values of CR. Values of CR (as defined) greater than 30:1 characterize fabric-damaging common regular bleach. By decreasing the ratio value, fabric protection progressively improves to a relatively broad maximum at a ratio value about 2:1.Type: GrantFiled: November 14, 2011Date of Patent: January 8, 2013Inventor: Lawnie Henderson Taylor

Patent number: 7285522Abstract: The invention provides methods, compositions and kits for increasing the brightness retention of a fabric laundered using a hypohalite-generating bleach by employing an amount of bromide-releasing compound sufficient to provide between 0.1 to about 1.5 moles of bromine ion to mole of available chlorine in a wash liquor to mitigate the negative effects of said hypohalite bleach on the optical brightener present in either the wash liquor or on said fabric. The invention also applies to fabrics washed using commercial laundry detergents which typically deliver an optical brightener into said wash liquor, said optical brightener generally exhibiting instability in the presence of said hypohalite bleaches.Type: GrantFiled: August 25, 2004Date of Patent: October 23, 2007Assignee: The Clorox CompanyInventor: Gregory van Buskirk

Patent number: 7246628Abstract: A method for controlling Listeria in floor drains wherein an aqueous solution composed of a chlorinated caustic material which is soft metal compatible is introduced into a drain where Listeria is present. In a preferred manner, the aqueous solution is introduced into the drain employing a hose end dispensing device having a foam producing nozzle. The resulting aqueous solution has a sufficient viscosity to remain in the drain for about 30 seconds to 10 minutes.Type: GrantFiled: February 21, 2006Date of Patent: July 24, 2007Assignee: JohnsonDiversey, Inc.Inventors: Dale Albert Grinstead, James H. Wilson, Jr., Thomas H. Beinkemper

Patent number: 7204931Abstract: A storable, stable composition that provides the effective antimicrobial benefits of halogenated agents is presented. The invention includes a water-soluble biocidal composition. The composition includes: about 0.01 to about 10 wt. % of a water-soluble inorganic halide; about 5 to about 60 wt. % of an oxidizing agent which, in aqueous solution, reacts with the inorganic halide to generate hypohalite ions; about 1 to about 15 wt. % of N-succinimide; and about 1 to about 30 wt. % of a pH buffering agent. The invention also includes a method of producing the above composition.Type: GrantFiled: July 15, 2005Date of Patent: April 17, 2007Assignee: Truox, Inc.Inventors: Perry L. Martin, Roy W. Martin

Patent number: 7196044Abstract: A warewashing detergent composition is provided according to the invention. The warewashing detergent composition includes a cleaning agent, an alkaline source, and a corrosion inhibitor. The cleaning agent comprises a detersive amount of a surfactant. The alkaline source is provided in an amount effective to provide a use composition having a pH of at least about 8. The corrosion inhibitor includes a source of aluminum ion and a source of zinc ion. The relative amounts of the source of zinc ion and the source of aluminum ion can be controlled to reduce visible filming when the warewashing detergent composition is used in the presence of hard water. Methods for using and manufacturing a warewashing detergent composition are provided.Type: GrantFiled: June 25, 2004Date of Patent: March 27, 2007Assignee: Ecolab, Inc.Inventors: Kim R. Smith, Keith E. Olson, Howie Kestell, Michael J. Bartelme, Steven E. Lentsch, Victor F. Man, Burton M. Baum, Terence P. Everson
