A Hand Sanitizer is a liquid generally used to decrease infectious agents on the hands. Formulations of the alcohol-based type are preferable to hand washing with soap and water in most situations in the healthcare setting. It is generally more effective at killing microorganisms and better tolerated than soap and water. It is also called hand antiseptic, hand rub, or hand rub, agent applied to the hands for the purpose of removing common pathogens. The sanitizer is a handy on-the-go way to help prevent the spread of germs when soap and water isn’t available. The Hand sanitizer can help kill microbes, but it isn't effective on all germs and will do nothing for other substances that may be on your hands.
