Quizplus · Accepted Answer

An antiseptic is a chemical agent that can safely be used externally on living tissue to destroy microorganisms or to inhibit their growth. Disinfectants are typically too harsh to be used on living tissue, and are better suited for surfaces or objects. Sanitizers are also intended for inanimate objects, and do not necessarily target microorganisms on living tissue. Germicide is a general term for a substance that kills germs, but does not specify whether it is safe to use on living tissue.
