An alcohol hand sanitizer is a liquid, gel, or foam that inactivates microorganisms on hands, primarily using ethanol or isopropyl alcohol (60-95% concentration) to denature proteins, killing germs like bacteria and viruses, and is ideal for quick use when soap and water aren't available, though less effective on visibly dirty hands. Formulations often include moisturizers like glycerol to prevent skin dryness, but should avoid toxic methanol.
