Sonoma Pharmaceuticals and MicroSafe Group DMCC Announce that U.S. EPA has Added Nanocyn® Hospital-Grade Disinfectant to List N for Use Against COVID-19

WOODSTOCK, Ga.--(BUSINESS WIRE)-- Sonoma Pharmaceuticals, Inc. (Nasdaq: SNOA), a global healthcare leader developing and producing patented Microcyn® technology-based stabilized hypochlorous acid (HOCl) products for a wide range of applications, including wound, eye, oral and nasal care, dermatological conditions and disinfectant use, and its partner, the MicroSafe Group DMCC, are pleased to announce that Nanocyn® hospital grade disinfectant has been added to the list of COVID-19 disinfectants maintained by the U.S. Environmental Protection Agency’s List N.

Nanocyn hospital-grade disinfectant was approved by the EPA for use as a disinfectant in April 2022 as the Company has previously announced. The addition to the COVID-19 disinfectant list represents an extension of this approval.

The EPA expects products on List N to kill all strains and variants of the coronavirus SARS-CoV-2 (COVID-19) when used according to the label directions. Before products can legally make claims that they can kill a particular pathogen such as SARS-CoV-2, the claim must be authorized by the EPA based on rigorous testing and strict review of the scientific data. The inclusion of Nanocyn on the EPA’s List N represents a major achievement for Nanocyn and Microcyn Technology.

In addition, Nanocyn, also known as MicroSafe® in Europe and West Asia, recently achieved European Standard (EN) 17272 for Airborne Room Disinfection. Achieving this EN Standard shows that Nanocyn/MicroSafe is capable of completely disinfecting a room contaminated with bacteria and viruses by fumigating the airspace when following the directions of use. This automated fumigation process of room disinfection enables healthcare and other facilities in Europe to more efficiently disinfect entire rooms and other surfaces.

“The MicroSafe Group is very pleased with Nanocyn being included on the EPA’s List N for disinfectants to be used against SARS-CoV-2 (COVID-19),” said Safwan Abdallah, COO of the MicroSafe Group. “Furthermore, Nanocyn’s contact time is 30 seconds for viruses. This coupled with its extraordinarily low toxicity profile as categorized by the EPA (lowest Category IV per 40 CFR 156.62) makes Nanocyn an important tool for curbing the spread of infection.”

“We are excited to see regulators in the U.S. and E.U. approve additional uses of Nanocyn and our Microcyn Technology,” said Amy Trombly, CEO of Sonoma. “Our own MicrocynRX® Skin & Wound care family of products has been used successfully in many varied healthcare settings for years to eradicate bacteria, viruses and fungi. We are eager to expand the role Microcyn Technology plays in improving the health and safety of people around the world.”
