Patent number: 7617798Abstract: An animal bedding mixture is disclosed herein. The animal bedding mixture includes a bedding material and a bedding material additive. Bedding material is preferably straw, sawdust, sand or recycled manure solids. The bedding material additive is preferably 60-99% by weight absorbent clay powder, 0.1 to 35% by weight chlorite salt, and 0.01-35% by weight sodium bisulfate or sodium percarbonate. The bedding material additive of the present disclosure is inert when dry and neither germicidal or acidic. However, when the additive is exposed to moisture, such as animal urine, the sodium bisulfate will acidify the liquid, causing the formation of hypochlorous acid and chlorine dioxide. Hypochlorous acid and chlorine dioxide are very powerful, broad spectrum germicides that have proven efficacy against E. coli, Staphylococcus aureus, and other micro-organisms commonly found in animal bedding.Type: GrantFiled: October 27, 2006Date of Patent: November 17, 2009Assignee: Technologies Holdings Corp.Inventor: Randal D. Stevenson

Publication number: 20090110754Abstract: A liquid biocide containing stabilized chlorine dioxide and hypochlorous acid for various uses, including use as a teat dip or dairy animals. The stable, prophylactic biocide consists essentially of 0.10-20.0% by weight of a chlorite salt, 0.1-3.0% by weight of an acid, 0.10-2.0% by weight of an alkaline agent, and the balance water. Chlorite salt reacts with the acid to form germicidal chlorine dioxide and hypochlorous acid. The acid constituency and the alkaline agent constituency regulate the pH of the solution such that the biocide is stable when mixed for a period greater than two months. The present disclosure also includes a method of producing a stable, prophylactic biocide for dairy cattle, the method comprising 0.10-20.0% by weight of a chlorite salt, 0.10-3.0% by weight of an acid, 0.10-2.0% by weight of an alkaline agent, and the balance water in a container, and sealing the container.Type: ApplicationFiled: December 12, 2008Publication date: April 30, 2009Inventor: Randal D.
