Any one of us can walk in to a supermarket and purchase a disinfectant/ Sanitiser in the confident belief that this product will protect us and our family. However, there are a number of important issues that should be taken into consideration. For example, is that product effective on the target microorganisms? And how quickly does it kill them?



Target microorganisms –  Typically, an anti-bacterial sanitiser will offer 99.9% kill of bacteria including Salmonella, Listeria, Influenza and E.Coli. However, the main concern at the moment is of course COVID-19, a virus, so an anti-bacterial sanitiser is not necessarily suited for this purpose.


Contact time –  There are of course disinfectants that have proven efficacy against viruses, but in assessing that efficacy it is important to note the contact time required – how long does the product have to be in contact with the virus before it is deactivated? This is important because extended contact times in laboratory tests are not practical in real world situations.


During a viral pandemic, it is important that appropriate surfaces are disinfected with products that quickly and effectively deactivate all of the main problematic pathogens including viruses. This means that all surfaces that are regularly touched should be disinfected, with sufficient contact time. NEMESIS eH2O has been tested and shown to deactivate a broad spectrum of pathogens within seconds – this includes Viruses, Influenza, E. Coli, S. Aureus, Norovirus, MRSA, Protozoa and C. Difficile. These tests have shown the ability of Nemesis eH2O to kill 99.9999% of harmful micro-organisms on contact.


Efficacy-  The percentage kill for a disinfectant is another vitally important consideration. The difference between 99.9% and 99.9999% may not seem like much, but in fact it means, for example, that Nemesis eH2O is 1,000 times more effective than a disinfectant claiming 99.9%. This is because Logarithmic reduction is the standard used for quantifying disinfection.
