Chlorocresol BP (PCMC)

Chlorocresol BP, also known as PCMC (Para-Chlorometa-Cresol), is a white to off-white crystalline powder with a characteristic phenolic odor. It is a chlorinated phenol derivative widely used as a broad-spectrum antimicrobial preservative. It exhibits effective bactericidal and fungicidal activity, making it a preferred preservative in pharmaceutical, cosmetic, and personal care products. Chlorocresol is valued for its stability, solubility in aqueous and alcoholic systems, and compatibility with various formulation types. It helps inhibit microbial growth, thereby enhancing product shelf life and safety.
