COVID19 Letter

An Open Letter Concerning Coronavirus (COVID-19)

When researching new technologies for the disinfection of bacteria and viruses, it is important to find a solution that is able to fully disinfect a surface, yet not be harmful to people or to the environment. Such a disinfectant exists. Stabilized super mixed oxidant solutions (SMOS) produced with Ionogen’s new technologies and powered with hypochlorous acid (HOCl) are the most effective disinfectants available.

While most traditional disinfectants require long dwell times, up to ten minutes, SMOS is shown to be effective in 60 seconds. This is an important factor as most facilities don’t have the time or the manpower to allow for long dwell times. Furthermore, many leading disinfectants have harsh chemicals that harm both the cleaning staff as well as surfaces. SMOS has been proven as a chlorine-based solution to be completely safe and non-toxic for staff and facilities due to its near-neutral pH and lack of harmful chemicals.

In recent years, governmental agencies have taken notice of HOCl and its efficacy. The EPA recognizes that chlorine is the most widely used disinfectant due to its ability to “[destroy] target organisms by oxidizing cellular material.”1 Hypochlorous Acid appears on the U.S. Food and Drug Administration’s list of Cleared Sterilants and High-Level Disinfectants with General Claims. In addition, the CDC states, “the microbiocidal activity of chlorine is attributed largely to undissociated hypochlorous acid.” 2 Powered with high concentration levels of HOCl not attained by other products, and along with other extremely active mixed oxidants, SMOS is the most effective disinfectant available.

With the most recent outbreak of Coronavirus COVID-19, the World Health Organization has recommended “[that] chlorine can be useful to disinfect surfaces, but they need to be used under appropriate recommendations.” 3 In the US, the Environmental Protection Agency (EPA) has suggested the use of disinfectants that are effective against enveloped viruses, which includes COVID-19. SMOS more than satisfies those criteria. 

Working to exceed the highest standards of public health, improving the health of people, and ensuring a clean and safe environment for all, the SMOS and HOCl solutions generated by Ionogen continue to advance the fields of sanitation and disinfection.
