Benzyldimethyldecylammonium chloride

Benzyldimethyldecylammonium chloride (CAS 965-32-2 ), also known as decyldimethylbenzylammonium chloride, is a quaternary ammonium compound used as a cationic surfactant and broad-spectrum biocide across industrial and consumer applications.

It disrupts microbial cell membranes, delivering effective antimicrobial action at low concentrations. In water treatment, it controls bacterial and algal growth in cooling towers, industrial process water, and swimming pool systems.

Personal care and cosmetics formulators incorporate it into preservative systems for rinse-off and leave-on products where microbial stability is a formulation requirement. This ensures product safety and shelf-life integrity.

Pharmaceutical and healthcare manufacturers use it as an active disinfectant ingredient in surface sanitizers, instrument disinfectants, and antiseptic preparations. It meets rigorous safety standards for clinical environments.

In food processing environments, it functions as a hard-surface sanitizer approved for use on food-contact surfaces under regulated concentrations. This helps maintain hygiene standards in commercial kitchens and factories.

The compound is supplied as an aqueous solution, typically at concentrations of 50% or 80% active content. It is available in technical and pharmaceutical-grade specifications to meet the requirements of regulated end markets.

Bulk supply is standard in intermediate bulk containers (IBCs) and drums, with packaging options scaled to industrial procurement volumes. This allows for efficient logistics and storage for large-scale manufacturing operations.
