Alcohol-based hand rubs are an example of an antiseptic. An antiseptic is a substance that prevents the growth or action of microorganisms by inhibiting their activity or by destroying them. The term is used especially for preparations applied topically to living tissue.
To be effective against some types of pathogens, including SARS-CoV-2, hand sanitizers need to have a strength of at least 60% alcohol and be used when hands are not visibly dirty.
Do not use hand sanitizer to disinfect frequently touched surfaces and objects.
