Patent number: 9873751Abstract: This invention pertains to a polymeric composition and an antimicrobial composition, each comprising a superabsorbent polymer (SAP), such as used in diapers and sanitary napkins, and peroxide. The superabsorbent material can be made by the process of treating a preformed SAP, such as a crosslinked polyacrylate salt, with a treatment solution comprising hydrogen peroxide dissolved in water, followed by drying. The resulting superabsorbent material has strong antimicrobial activity. Optionally, the treatment solution may also contain a metal salt, including those of zinc, zirconium, and magnesium.Type: GrantFiled: November 14, 2014Date of Patent: January 23, 2018Assignee: Quick-Med Technologies, Inc.Inventors: William Toreki, Susan Leander, Gerald M. Olderman

Patent number: 8926999Abstract: This invention pertains to method for imparting a durable antimicrobial activity to substrates, particularly textiles. An acetate-free metal and peroxide antimicrobial treatment formulation is prepared from a metal derivative, hydrogen peroxide and a source of hydroxide ion. The substrate is treated with the composition and dried to afford the treated substrate with antimicrobial activity. Zinc salts, ions, or complexes are preferred.Type: GrantFiled: September 14, 2012Date of Patent: January 6, 2015Assignee: Quick-Med Technologies, Inc.Inventors: William Toreki, Albina Mikhaylova, Susan Leander, Bernd Liesenfeld, Gerald M.

Patent number: 8545862Abstract: Anionic polyelectrolytes are used as binding agents to reduce the solubility of cationic antimicrobial polyelectrolytes. Ionic attraction between the anionic stabilizing polyelectrolytes and the antimicrobial cationic polyelectrolytes results in formation of a polyelectrolyte complex (PEC). A treatment liquid comprising a stable colloid, suspension, dispersion, solution, coacervate, or emulsion of the PEC in an aqueous carrier is used to treat an article, thus coating, infiltrating, or infusing the PEC onto or into the article. Subsequent drying results in an antimicrobial article wherein the PEC is bound to the article and is significantly less prone, relative to either of the component polyelectrolytes, to being washed, leached, leaked, extracted, or migrated from the antimicrobial article during use, or when exposed to aqueous fluids or solvents.Type: GrantFiled: July 2, 2010Date of Patent: October 1, 2013Assignee: Quick-Med Technologies, Inc.Inventors: William Toreki, David N. Moore, Bernd Liesenfeld, Albina Mikhaylova, Gerald M. Olderman

Publication number: 20130011491Abstract: This invention pertains to method for imparting a durable antimicrobial activity to substrates, particularly textiles. An acetate-free metal and peroxide antimicrobial treatment formulation is prepared by adjusting the pH of a mixture of a metal salt in aqueous hydrogen peroxide to about 7.5. The substrate is treated with the composition and dried to afford the treated substrate with antimicrobial activity. Zinc salts, ions, or complexes are preferred.Type: ApplicationFiled: September 14, 2012Publication date: January 10, 2013Applicant: QUICK-MED TECHNOLOGIES, INC.Inventors: William Toreki, Albina Mikhaylova, Susan Leander, Bernd Liesenfeld, Gerald M.

Patent number: 7709694Abstract: This invention relates to methods and compositions for materials having a non-leaching coating that has antimicrobial properties. The coating is applied to substrates such as gauze-type wound dressings. Covalent, non-leaching, non-hydrolyzable bonds are formed between the substrate and the polymer molecules that form the coating. A high concentration of anti-microbial groups on multi-length polymer chains and relatively long average chain lengths, contribute to an absorbent or superabsorbent surface with a high level antimicrobial effect.Type: GrantFiled: September 28, 2001Date of Patent: May 4, 2010Assignees: Quick-Med Technologies, Inc., University of Florida Research Foundation, Inc.Inventors: Christopher D. Batich, Gregory Schultz, Bruce A. Mast, Gerald M. Olderman, David S. Lerner, William Toreki
