Sodium dichloroisocyanurate

Sodium dichloroisocyanurate (CAS 2893-78-9), commonly known as NaDCC or troclosene sodium, is a chlorine-releasing compound used across industrial and municipal sectors as a disinfectant, biocide, and bleaching agent. It delivers controlled, stable active chlorine in solid form, making it a practical alternative to liquid chlorine systems where handling and dosing precision matter for large-scale operations.

In water treatment, NaDCC is used to disinfect drinking water, swimming pools, and wastewater streams, where its consistent chlorine release allows accurate dosing at scale for safety and compliance. Food processing facilities rely on it for surface sanitation and equipment disinfection, meeting hygiene standards without the corrosion risks associated with traditional hypochlorite solutions.

In textile and paper manufacturing, it functions as a bleaching agent to whiten fibers and pulp without the process instability of gaseous chlorine, ensuring a more controlled production environment. Personal care formulators incorporate it into effervescent disinfectant tablets and antiseptic products where a stable, dry chlorine source is required for long-term shelf stability and efficacy.

Sodium dichloroisocyanurate is supplied as a white powder, granules, or compressed tablets, with granule size and tablet weight customized to specific industrial application requirements. Standard grades include technical, food-grade, and potable water treatment specifications, with active chlorine content typically around 60–62% for bulk bags, drums, and smaller packaged formats.
