Hand sanitiser can kill coronavirus, but its overall effectiveness very much depends on the type you use.
Homes, businesses and schools across the UK are potentially using hand sanitisers that can take up to two minutes to kill the virus, as opposed to the standard 20-30 seconds – and could be less effective, too, a Sky News investigation found.
There are two key types of hand sanitisers: those with alcohol in them, and those without. And experts agree you want to be opting for the former, as alcohol has historically been pretty effective at killing coronaviruses.
The coronavirus has a lipid envelope which protects its structure. When you use an alcohol-based hand sanitiser, the alcohol affects this structure and, in doing so, deactivates the virus. When a person rubs it into their hands, it’s essentially reducing the virus to a safe level so you won’t be spreading it around elsewhere.
