A recent study by the Journal of Hospital Infection looked at how long the coronavirus can live on inanimate surfaces and then tested various agents to find out the best way to kill it.
The study, entitled "Persistence of coronavirus on inanimate surfaces and their inactivation with biocidal agents" reviewed all available published scientific studies on any previously known coronaviruses (including SARS and MERS) to determine how long the viruses can survive when left behind on a hard surface.
As the study noted, the coronavirus is "spread via droplets, contaminated hands or surfaces." Specifically, the viruses can survive on surfaces such as metal, glass or plastic for to up nine days. That's a long time for a contaminated surface to remain infectious and makes items that people come into contact with every day such as gas pumps, canned goods brought home from the grocery store and even coins, keys and door knobs potential sources of infection.
The study then looked at a variety of biocidal agents to see which might be effective in killing off the virus living on these surfaces. The study concluded that a solution of "62 to 71% ethanol significantly reduces coronavirus infectivity on surfaces within 1 min exposure time."
We created our hand sanitizer manufacturing protocol based on this study, using a minimum of 72% ethanol to ensure maximum virus fighting capability.
Stay safe and sanitize often!
