Etymology
The term "hand sanitizer" is a compound noun, combining "hand," from Old English hond, and "sanitizer," derived from the Latin sanitas meaning health.
Usage
In most settings, hand washing with soap and water is generally preferred. Hand sanitizer is less effective at killing certain kinds of germs, like 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.
Composition
Hand sanitizers were developed for use after washing hands or for those times when soap and water are not available. They are gels that contain alcohol in order to kill the germs present on the skin. The alcohol works immediately and effectively in order to kill bacteria and most viruses.
Types
Hand sanitizers come in two major types: alcohol-based and alcohol-free. Alcohol-based hand sanitizers contain varying amounts and types of alcohol, often between 60% and 95% and usually isopropyl alcohol, ethanol (ethyl alcohol), or n-propanol. Alcohol-free hand sanitizers contain quaternary ammonium compounds (usually benzalkonium chloride) instead of alcohol to reduce microbes.
