Chloroxylenol BP
Chloroxylenol BP is a pale yellow to colorless crystalline solid with a mild phenolic odor. It is a broad-spectrum antimicrobial agent widely used for its bactericidal, fungicidal, and antiviral properties. Chemically known as 4-chloro-3,5-dimethylphenol, Chloroxylenol acts by disrupting microbial cell membranes and inhibiting enzyme systems, making it effective against many gram-positive and some gram-negative bacteria, fungi, and viruses. Its relatively low toxicity and skin irritation profile compared to other phenols have made it a preferred active ingredient in antiseptics, disinfectants, and preservative formulations across pharmaceutical, personal care, household, and industrial applications.
