Hydroxydichlorodiphenyl ether

Hydroxydichlorodiphenyl ether (CAS 3380-30-1 ), also known as DCPP or 5-chloro-2-(4-chlorophenoxy)phenol, is a chlorinated diphenyl ether compound used industrially as an antimicrobial and preservative agent.

It functions by inhibiting microbial growth across a broad spectrum of bacteria and fungi, making it a reliable active ingredient in preservation-critical applications for various industrial sectors.

In personal care and cosmetics, it is incorporated into rinse-off and leave-on formulations as a preservative to extend product shelf life and maintain microbial safety standards during consumer use.

Textile and leather processing operations use it to protect finished goods and process liquors from bacterial and fungal degradation during storage and transit, ensuring material integrity and quality.

Water treatment systems employ it as a biocidal agent to control microbial contamination in industrial process water and cooling circuits, preventing biofilm formation and system inefficiency.

Pharmaceutical manufacturing applies it as an antimicrobial intermediate or active preservative component in topical and non-sterile preparations, adhering to strict safety and efficacy protocols.

Hydroxydichlorodiphenyl ether is typically supplied as a white to off-white crystalline powder. It is available in technical and pharmaceutical grades, with purity specifications commonly ranging from 98% upward.

Packaging options generally include multi-kilogram bags and drums suited to industrial procurement volumes, ensuring safe handling and transport for large-scale manufacturing requirements.
