Sodium p-chloro-m-cresol

Sodium p-chloro-m-cresol (CAS 15733-22-9), the sodium salt form of chlorocresol, is a broad-spectrum antimicrobial agent used across personal care, pharmaceutical, and industrial formulations.

Its water-soluble character makes it a practical alternative to the free acid form where pH compatibility and ease of incorporation are priorities for formulators during the manufacturing process.

In cosmetics and topical pharmaceutical products, it functions as a preservative in creams, lotions, and ointments, controlling microbial growth across both gram-positive bacteria and fungi.

Industrial cleaning and disinfectant manufacturers incorporate it into hard-surface sanitizers and instrument disinfection products where reliable bactericidal performance is required for safety.

Water treatment applications use it as a biocide to control microbial fouling in process water and cooling systems. Personal care formulators also select it for preservation of various products.

It is particularly effective for rinse-off and leave-on products where the neutral-to-alkaline pH range aligns with its optimal activity window for maximum antimicrobial efficacy and stability.

Sodium p-chloro-m-cresol is supplied as a white to off-white powder or crystalline solid. It is available in technical and pharmaceutical-grade specifications to meet the requirements of markets.

Packaging typically ranges from kilogram-scale bags to bulk sacks depending on application volume. This material is handled according to strict quality standards to ensure consistent performance.
