Sanitizer is a personal care and health hygiene product that helps kill germs and bacteria on hands when soap and water are not readily available. It contains alcohol, typically in concentrations of 60% or higher, which is effective in destroying harmful microorganisms. Sanitizers are available in different forms such as gel, spray, and foam, and are often enhanced with moisturizing agents to prevent skin dryness. The use of sanitizer has become an essential part of maintaining good hygiene practices, particularly in public places, and during viral outbreaks.
