3,3',4',5-Tetrachlorosalicylanilide
Antiseptic soaps and skin preparations once contained 3,4',5-tetrachlorosalicylanilide, a halogenated antimicrobial that disrupts microbial cell membranes and denatures proteins on contact. That non-specific chemical action gives rapid broad-spectrum activity against bacteria and fungi on the skin surface, and it operates without a defined molecular receptor. Reports of skin sensitisation and of photosensitivity reactions in exposed individuals ended its widespread use, and the compound is now rarely encountered in medical or consumer products. Photocontact allergy associated with halogenated salicylanilides is a recognised episode in the history of cosmetic and antiseptic regulation. The molecule is C13H7Cl4NO2 with a mass near 351.0 g/mol.
An antimicrobial compound that was historically used in antiseptic soaps and skin preparations to kill bacteria and fungi on the skin's surface. It fell out of widespread use after concerns arose about skin sensitization and photosensitivity reactions in some individuals. Today it is rarely encountered in modern medical or consumer products.
