Description
Sodium dichloroisocyanurate (CAS 2893-78-9), commonly known as NaDCC, SDIC, ACL60, or DCCNA, is a chlorine-releasing compound used as a disinfectant and bleaching agent. It carries no assigned E-code and is traded under several commercial designations including OCI56.
In water treatment, NaDCC dissolves to release hypochlorous acid, which disrupts microbial cell membranes and eliminates bacteria, algae, and viruses at controlled dosage levels. In textile and paper processing, it functions as an oxidative bleaching agent, breaking chromophore bonds to achieve whitening without mechanical abrasion.
NaDCC is available in powder and lump grades, with purity levels suited to industrial and food-contact applications. It falls under REACH regulation and is handled as a classified oxidising substance under EU GHS requirements. Standard packaging formats include 25 kg bags and bulk quantities; buyers should confirm grade specifications against intended application requirements.
