If you feel uneasy about touching a bottle of communal hand sanitiser in a public place like a shopping mall because you think it might be unsafe, the World Health Organisation (WHO) says there is nothing to worry about.
“Once you have sanitised your hands you have disinfected them from any germs that may have been on the bottle. If everyone uses sanitiser in a public place, such as a supermarket entrance, the risk of germs on communal items will be lower and keep everyone safe,” says the organisation.
Hand sanitisers have become popular globally since the start of the Covid-19 pandemic last year.
Using an alcohol-based hand sanitiser to disinfect hands and surfaces was one of the first recommendations by the organisation. A minimum of 70% alcohol content is required if alcohol like ethanol, isopropanol or n-propanol is the main ingredient. Otherwise, 60% alcohol content is allowed if there are other active ingredients.
