Dichloroxylenol

Dichloroxylenol (CAS 133-53-9), also known as DCMX and marketed under the name Decasept, is a chlorinated phenolic compound used as a broad-spectrum antimicrobial preservative and biocide.

Its activity against bacteria, fungi, and mold makes it a functional ingredient where microbial control is a formulation or process requirement across industrial and consumer-facing applications.

In personal care and cosmetics, DCMX is incorporated into antiseptic washes, medicated soaps, and topical disinfectant formulations as the active preservative agent for various product lines.

Textile and leather processors use it to prevent microbial degradation during wet processing and in finished goods requiring long-term preservation against environmental factors and decay.

In plastics and polymer manufacturing, it functions as an antioxidant and stabilizer, protecting materials from oxidative breakdown during processing and extending the overall service life.

Pharmaceutical manufacturers also source it as an intermediate in the synthesis of antimicrobial active ingredients. It is supplied as a white to off-white crystalline powder for industrial use.

Technical grade is the most common commercial form, with pharmaceutical-grade material available for regulated applications requiring tighter purity specifications and adherence to strict manufacturing protocols.

Buyers typically source it in multi-kilogram bags or drum quantities depending on application volume. This ensures consistent supply chains for large-scale manufacturing and specialized chemical processing.
