Patent number: 8017032Abstract: A solid composition in the form of a tablet that generates and releases a biocidal solution comprising at least chlorine dioxide with an enhanced weight percent yield is presented. The composition comprises reactants capable of in-situ generation of chlorine dioxide comprising a chlorite donor that is coated with a gel-forming material that slows the rate of dissolution of the high solubility chlorite donor, a free halogen donor, and an acid source, resulting in an unexpectedly high weight percent yield and providing a controlled release of biocidal solution. The compositions of the invention show improved environmental stability which can reduce the cost of packaging and significantly increase the utility of the composition. The controlled release allows the use in multi-tablet chemical dispensers which may otherwise induce potentially explosive conditions or allow rapid release of the biocidal solution thereby inducing a spike in chemical concentration rather than a controlled and sustained release.Type: GrantFiled: August 25, 2010Date of Patent: September 13, 2011Assignee: Truox, Inc.Inventor: Roy W. Martin

Patent number: 7695631Abstract: A method and composition for reducing chemical oxygen demand is presented. The composition includes a persulfate donor and a transition metal catalyst in contact with the persulfate donor. When the composition is contacted by water, the transition metal catalyst reacts with persulfate and reduces the persulfate concentration in the water. The composition allows the use of persulfate, which is known to cause irritation to users of aquatic facilities (e.g., pools, spas) that come in contact with it. As the persulfate concentration is reduced rapidly in the water by the catalyzed reaction, the persulfate-containing cleaning product may even be used while the aquatic facilities are being used. Optionally, a free halogen donor may be incorporated into the composition. The composition may be in the form of powder, granules (coated or uncoated), or agglomerate.Type: GrantFiled: March 26, 2009Date of Patent: April 13, 2010Assignee: Truox, Inc.Inventor: Roy W Martin

Patent number: 7572390Abstract: A method and composition for reducing chemical oxygen demand is presented. The composition includes a persulfate donor, a transition metal catalyst in contact with the persulfate donor, and a cationic electrolyte. When the composition is contacted by water, the transition metal catalyst reacts with persulfate and reduces the persulfate concentration in the water. The composition allows the use of persulfate, which is known to cause irritation to users of aquatic facilities (e.g., pools, spas) that come in contact with it. As the persulfate concentration is reduced rapidly in the water by the catalyzed reaction, the persulfate-containing product may be applied while the aquatic facilities are being used. A free halogen donor may be incorporated into the composition. The composition may be in the form of powder, granules (coated or uncoated), or agglomerate. The cationic electrolyte facilitates the removal of the catalyst from the water.Type: GrantFiled: September 14, 2005Date of Patent: August 11, 2009Assignee: Truox, Inc.Inventor: Roy W. Martin

Patent number: 7534367Abstract: A method of treating a peroxygen compound (e.g., potassium monopersulfate) for use in applications where controlled release rate, exposure to incompatible compounds, and/or moisture is presented. The method incorporates coating the peroxygen compound with one or more of the following polymers: 1) chitin/chitosan, 2) carboxylate/sulfonate copolymer or tertiary polymer, and 3) carboxylate polymer selected from polymaleic acid, polyepoxysuccinic acid and/or phosphinocarboxylate polymers. Optionally, the peroxygen compound is also coated with an inorganic salt layer and a silicate layer. Potassium monopersulfate coated with an organic polymer is useful in reduced allergenic formulations and as an anti-caking agent. When the organic polymer is a polysaccharide, the coated potassium monopersulfate is also effective for shock treatment of water systems (e.g., pools). The oxidizing composition prepared with this method has a prolonged shelf life while demonstrating good solubility during use.Type: GrantFiled: June 28, 2004Date of Patent: May 19, 2009Assignee: Truox, Inc.Inventor: Perry L.

Patent number: 7465410Abstract: A reactor for an in-situ production of a chemical product in high yield are presented. The reactor, which may be placed in a main solvent, includes a core and a reactor wall around the core. The reactor wall allows controlled permeation of the main solvent to the core. The core contains a reactant that reacts to produce a target product upon being contacted by a main solvent. The target product leaves the reactor at a controlled rate. Because the amount of the main solvent that permeates into the reactor is controlled, a high concentration of the reactant is maintained inside the reactor, resulting in a higher yield of the desired chemical product than if the reactants were directly added to the body of main solvent.Type: GrantFiled: February 18, 2005Date of Patent: December 16, 2008Assignee: Truox, Inc.Inventors: Perry L.

Patent number: 6589443Abstract: Aqueous bleach solutions can be made by directing a spray of water onto a bulk or shaped solid (brick, tablet, block, etc.) comprising a continuous solid phase of an encapsulated source of an active halogen bleach or a solid comprising a source of an oxidizing active halogen bleach, and an encapsulated oxidizing halogen bleach source. Such shaped solids can be used to dispense uniform quantities of an aqueous bleach concentrate to bleaching locus such as a washing machine. The tablets can be made from the encapsulated bleach or from a powder mixture of a particulate, granulated or powdered unencapsulated source of active oxidizing bleach and an encapsulated source of active oxidizing bleach by forming the powder mixture into a desired shape. Such a shaped solid bleach can be packaged in a container and can then be contacted with an aqueous spray in a dispenser to create a solution of active bleach for cleaning bleaching processes.Type: GrantFiled: August 7, 1996Date of Patent: July 8, 2003Assignee: Ecolab Inc.Inventors: Keith E.
