Publication number: 20230404821Abstract: This invention discloses novel particulate compositions made by modifying Superabsorbent Polymer (SAP) and other high surface area substrates to create granules that exhibit broad-spectrum antimicrobial and enzyme-inactivating properties, and that can directly neutralize certain malodorants and other undesirable chemical entities, such as toxins. This is accomplished by the direct interaction of the modifying moieties with: (1) vital components of bacteria, fungi, yeasts, and viruses; (2) enzymes, such as those that are responsible for the generation of malodorants and other toxic volatile compounds; and (3) certain malodorants and other undesirable compounds that are susceptible to oxidative or halogenation reactions that can neutralize their odors or toxicities. Chemical modifications of granular materials are accomplished by exposure to organic solvents containing soluble or dispersible N-halamine.Type: ApplicationFiled: May 12, 2023Publication date: December 21, 2023Inventors: Jeffrey F. Williams, Shelby D. Worley
