Which term describes a substance that inhibits the growth of bacteria?

The correct term to describe a substance that inhibits the growth of bacteria is antiseptic. Antiseptics are specifically formulated to be used on living tissues to reduce the risk of infection by inhibiting bacterial growth. They can be applied to cuts, abrasions, or surgical sites to help prevent pathogens from entering the body.

On the other hand, disinfectants are chemical agents used primarily on surfaces to kill or inactivate harmful organisms, but they are not safe for use on skin or mucous membranes. Analgesics refer to substances that relieve pain but do not necessarily have any antibacterial properties. Astringents are agents that cause tissue to contract, which can sometimes help with minor bleeding or skin irritations but are not primarily aimed at inhibiting bacterial growth.
