Sodium dichloroisocyanurate (INN: sodium troclosene, troclosenum natricum or NaDCC or SDIC) is an inorganic compound. It is a colourless, water-soluble solid. It is a widely used cleansing agent and disinfectant.^[1] The dihydrate is also known (CAS# 51580-86-0) as is the potassium salt (CAS#2244-21-5).

Uses

It is mainly used as a disinfectant, biocide, industrial deodorant and detergent. It is found in some modern water purification tablets/filters. It is more efficient than formerly used halazone water disinfectant. In these applications, it is a source of slow release of chlorine in low concentrations at a relatively constant rate. As a disinfectant, it is used to sterilize drinking water, swimming pools, tableware and air, fight against infectious diseases as routine disinfection,

It can be used as a preventive for disinfection and environmental sterilization, in raising silkworm, livestock, poultry and fish, and also can be used to prevent wool from shrinking, bleaching textiles and cleaning industrial circulating water.
