Which of the following best defines an antiseptic?

An antiseptic is best defined as a substance that inhibits microorganisms on living tissues. This definition is centered on the specific application of antiseptics, which are designed to be used on skin or mucous membranes to prevent infection without harming the living tissue. Antiseptics are used in various settings, such as healthcare, to clean wounds or prepare the skin before procedures.

The role of antiseptics distinguishes them from disinfectants, which are meant for inanimate surfaces. The ability to inhibit rather than completely kill microorganisms is critical, as a full eradication might not be necessary or safe for living tissues. Understanding this distinction is crucial for microbial control in medical and clinical environments, as it ensures that the integrity and safety of the living tissues are preserved while still reducing the risk of infection from potential pathogens.
