Sodium Dichloroisocyanurate (SDIC), with the chemical formula C₃Cl₂N₃NaO₃, is a chlorinated organic compound that has revolutionized modern disinfection practices. With an active chlorine content typically ranging between 56% and 60%, SDIC offers a powerful, fast-acting, and highly stable alternative to traditional chlorine compounds.
Key Advantages of SDIC
- Rapid Dissolution: Unlike calcium hypochlorite or chlorinated lime, SDIC dissolves quickly in water, releasing free available chlorine almost instantly.
- Neutral pH Release: The dissolution produces a near-neutral pH solution (pH 6.0–7.0), making it gentle on surfaces, fabrics, and skin.
- Long Shelf Life: Properly stored SDIC retains over 95% of its active chlorine content for up to 24 months.
- Zero Residue: Leaves no insoluble deposits, ideal for use in clear-water applications such as drinking water and beverage processing.
Primary Applications
SDIC is widely deployed across the following sectors:
- Drinking water disinfection — both municipal and emergency supply systems
- Hospital and clinical surface sterilization
- Food and beverage equipment cleaning (CIP/COP systems)
- Textile bleaching and wool shrink-resistance treatment
- Aquaculture pond sanitization and livestock biosecurity
