Hand sanitizer is an alcohol-based solution used to disinfect hands and eliminate germs when soap and water are not available. It typically contains ethanol or isopropanol as the active ingredient, which effectively kills bacteria and viruses. Many formulations also include moisturizers to prevent skin dryness and fragrances for a pleasant scent. Regular use helps reduce the transmission of infectious diseases, especially in situations where handwashing facilities are limited.
