Used primarily as a topical antimicrobial agent, especially in antiseptic soaps, creams, and wound treatments. It is effective against a broad spectrum of bacteria and fungi, making it suitable for skin disinfection and in over-the-counter first aid products. Its activity is particularly notable in controlling odor-causing microorganisms, so it has been included in deodorants and foot care products. Due to concerns over skin sensitization and environmental persistence, its use has declined in some regions, but it remains in select medicinal and cosmetic formulations where prolonged antimicrobial action is needed.
