Chloroxylenol

CAS: 88-04-0

Overview

Chloroxylenol (CAS 88-04-0 ), commonly known as PCMX, is a broad-spectrum antimicrobial active used across personal care, healthcare, and industrial formulations. It delivers effective bactericidal and fungicidal activity.

This chemical is effective against a wide range of gram-positive and gram-negative organisms, making it a reliable preservation and disinfection ingredient for formulators and manufacturers worldwide.

In personal care and OTC healthcare products, PCMX is the active ingredient in antiseptic hand soaps, surgical scrubs, wound care preparations, and medicated skin cleansers for professional use.

Industrial and institutional disinfectant formulations rely on it for surface sanitization in healthcare facilities, food processing environments, and various veterinary settings requiring high hygiene standards.

Textile and leather processors use it as a preservative biocide to prevent microbial degradation during wet processing and storage. In plastics, it functions as an antioxidant and stabilizer.

Chloroxylenol is supplied as a white to off-white crystalline powder or flakes. Standard grades include USP , BP , and technical grade, with pharmaceutical specifications being the primary requirement.

Minimum purity of 98–99% is typical for pharmaceutical-grade material, while technical grade serves industrial preservation and polymer applications where high-level purity is less critical for the end result.
