Synexis Dry Hydrogen Peroxide Technology Inactivates Infectious SARS-CoV-2 Virus On Surfaces

 

LENEXA, Kan., July 15, 2021 /PRNewswire/ -- Synexis® LLC, a pioneer in microbial reduction and sole developer of patented technology that creates Dry Hydrogen Peroxide (DHP™) for occupied spaces, today announced that DHP™ begins reducing viral load in larger indoor spaces (total volume 5,940 ft3) in 45 minutes, and significantly reduces surface levels of infectious SARS-CoV-2 virus in 120 minutes of continuous treatment.1 These results were included in an independent study published today in the American Journal of Infection Control.

"Under rigorous laboratory test conditions, the portable Synexis Dry Hydrogen Peroxide device significantly reduced the levels of infectious SARS-CoV-2 virus, the virus which causes COVID-19, on hard surfaces, in just two hours," said Stephen Higgs, Ph.D., F.R.E.S., F.A.S.T.M.H., associate vice president for research, director, Biosecurity Research Institute (BRI), the lead investigator on the study.

To determine if DHP technology was active against SARS-CoV-2 viral contamination in larger spaces, scientists at the BRI exposed virus-contaminated surfaces (glass slides) to DHP technology for up to 24 hours and used an ambient-air, untreated room as the control environment. The study was conducted in 50m2 rooms (approximate total volume 5,940 ft3), simulating a more real-world environment with standard air exchanges. Samples were then analyzed to learn whether DHP technology could enhance the decay of infectious SARS-CoV-2 particles. Viral samples in the room treated with DHP began to show numerical reductions versus the ambient-air control group at 45 and 60 minutes and reached statistical significance at 120 minutes. After 120 minutes of DHP treatment, SARS-CoV-2 concentrations were significantly reduced by 98.7% (1.8log10TCID50/ml in the DHP-treated room versus 3.1log10TCID50/ml in the untreated room, p = 0.01).1 Additionally, one-third (33.3%) of DHP-treated samples did not contain detectable viruses at both 240 and 1,440 minutes after the initiation of treatment.

"Cleaner surfaces reduce the risk of indirect contact transmission of SARS-CoV-2, which is essential for the safe reopening of businesses and schools," said Eric Schlote, CEO of Synexis. "This peer-reviewed study shows that DHP significantly reduces SARS-CoV-2 on surfaces. It adds to a growing body of evidence showing DHP is effective at reducing bacteria, mold and viruses, including SARS-CoV-2 that causes COVID-19."

Synexis technology deploys DHP to actively clean the air and surfaces.2 DHP molecules travel throughout an enclosed space to reduce viruses, bacteria, mold, odors and many insects.3 Generated from ambient humidity and oxygen naturally present in the environment, DHP can be effectively delivered in occupied spaces at levels well below occupational airborne safety standards established by OSHA, which allows for continuous microbial reduction without disturbing normal operations and workflow.4 DHP is able to impact contaminants in the air and on surfaces in hard-to-reach places.
