Define hand antiseptic.

Hand antiseptic refers to a substance that is used to kill or inhibit the growth of microorganisms on the skin, particularly on the hands. It is commonly used in healthcare settings to reduce the risk of spreading infections. Hand antiseptics can come in the form of gels, foams, or liquids and typically contain alcohol or other active ingredients that are effective at killing bacteria, viruses, and other germs.

A hand antiseptic is an antimicrobial agent applied to the hands to reduce the number of microorganisms on the skin. Hand antiseptics are typically used in healthcare settings to prevent the spread of infection, but can also be used in other settings, such as in the food industry or in homes. Hand antiseptics can be either alcohol-based or non-alcohol-based. Alcohol-based hand antiseptics contain at least 60% alcohol and work by killing microorganisms on the skin. Non-alcohol-based hand antiseptics contain other antimicrobial agents, such as chlorhexidine or triclosan.
