Hand sanitisers can help protect you from infections — both viral and bacterial — when used correctly and in the right scenarios. This means applying a hand sanitizer that is at least 60% alcohol, using the directed amount (read the label), rubbing it in completely and waiting for it to dry before doing anything else with your hands.
Most alcohol-based hand sanitisers have ethanol, isopropanol (isopropyl alcohol), n-propanol, or a combination of 2 of these products.
Basically alcohol attacks and destroys the envelope protein that surrounds some viruses, including coronaviruses. This protein is vital for a virus’s survival and multiplication.
An alcohol concentration of 60-95% is most effective. High concentrations are not ideal as proteins aren’t denatured as easily without water. Water also slows down the evaporation of alcohol, which ensures alcohol has enough contact time on your hands to kill germs before evaporating. It takes a bit of time for the alcohol to denature microbial proteins. At concentrations below 60%, there is not enough alcohol to disrupt the bilayer of the virus. For SARS-CoV-2, an ethanol concentration of 60-70% and 70% for isopropyl alcohol proves to be effective against the virus.
