Patent number: 11596149Abstract: A method of preparing a disinfecting composition comprising charged polyethylenimine (PEI), the method comprising adding a base to an aqueous solution comprising a linear PEI hydrochloride solution to provide a linear PEI salt solution with a pH between 9-11, adding a first organic acid to reduce the pH to less than 7, removing about 20% to 100% of the salt from the solution, and optionally adding water and/or a second organic acid to obtain the disinfecting composition with a pH of 2-7. The method can further comprise adding at least one metal salt to the disinfecting composition. The resulting disinfecting solution can be used to provide antimicrobial products with enhanced antimicrobial performance, reduced toxicity, and/or able to leave a persistent “kill-later” film.Type: GrantFiled: May 4, 2021Date of Patent: March 7, 2023Assignee: eXion Labs Inc.Inventors: Marion L. Chiattello, Mark Oman

Publication number: 20220401345Abstract: Provided is a polymer-based antimicrobial composition that is non-toxic, water soluble, and that mitigates the transmission of infectious diseases from surfaces. The composition comprises a cationic polymer, at least one adhesion promoter, optionally organic and/or inorganic particles that are photocatalytically active in visible light, and a carrier, in which the components of the composition are not covalently bound to one another. Also provided is an antimicrobial composition that comprises at least (i) a polyethylenimine-based polymer and a carrier or (ii) an organic and/or inorganic particle that is photocatalytically active in visible light, an adhesion promoter, and a carrier. The antimicrobial compositions can be applied to disinfect a surface and to form residual self-sanitizing films on the surface that are removable.Type: ApplicationFiled: July 20, 2022Publication date: December 22, 2022Applicant: eXion labs Inc.Inventors: Marion L.
