Regular Soap Bars Are Highly Efficient At Killing The Coronavirus COVID-19
To say that times are trying at the moment is an understatement! Out of the blue it seems, the coronavirus (or as COVID-19 as we now know it) has struck, and is now taking over our day-to-day lives. We're not here to analyse the pro's and cons of official advice, or to say what should or should not be done in light of this unprecedented crisis as there are already a lot of 'opinions' floating around on those matters!
One thing however, that is universally recognised as true (which is why medical professionals are forever doing it), is that hand washing with regular bar soap does affectively kill the coronavirus and keep you safe.
There have been serious shortfalls in anti-bacterial soaps and hand wash in the shops recently, due to the misguided belief that it is only these soaps with anti-bacterial properties that can kill viruses. This in fact is not true. Regular soap bars are in fact a highly efficient way of killing (in this case) the coronavirus virus when it’s on your skin.
In an article for The Guardian Newspaper, Pall Thordarson professor of chemistry at the University of New South Wales, Sydney explains why.
"Soap contains fat-like substances known as amphiphiles, some of which are structurally very similar to the lipids in the virus membrane. The soap molecules “compete” with the lipids in the virus membrane. This is more or less how soap also removes normal dirt from the skin.
Alcohol-based products contain a high-percentage alcohol solution (typically 60-80% ethanol) and kill viruses in a similar fashion. But soap is better because you only need a fairly small amount of soapy water, which, with rubbing, covers your entire hand easily. Whereas you need to literally soak the virus in ethanol for a brief moment, and wipes or rubbing a gel on the hands does not guarantee that you soak every corner of the skin on your hands effectively enough."
Of course using an alcohol-based sanitiser is advised when bar soaps and water are not available, but simple soap and water, whether anti-bacterial or not can help protect you against a virus such as coronavirus COVID-19.
