Hand sanitizer is a liquid, gel, or foam generally used to decrease infectious agents on the hands.
In most settings hand washing with soap and water is generally preferred. Hand sanitizer is less effective at killing certain kinds of germs, such as norovirus and Clostridium difficile and unlike soap and water, it cannot remove harmful chemicals. People may incorrectly wipe off hand sanitizer before it has dried, and some are less effective because their alcohol concentrations are too low.
Alcohol-based hand sanitizer works against a wide variety of microorganisms but not spores. compounds such as glycerol may be added to prevent drying of the skin.
Non-alcohol based versions typically contain benzalkonium chloride or triclosan; but are less effective than alcohol-based ones.
Alcohol has been used as an antiseptic as early as 1363, with evidence to support its use becoming available in the late 1800s. It is on the World Health Organization’s List of Essential Medicines.
