Sodium Dichloroisocyanurate: Uses, Benefits, and Safety
Sodium dichloroisocyanurate (SDIC) is a widely used chemical compound known for its strong disinfectant, sanitizer, and bleaching properties. It belongs to the family of chlorinated isocyanurates and is valued for its stability, efficiency, and cost-effectiveness. SDIC is commonly found in tablet, powder, or granular form and is a trusted agent in water treatment, public health, and industrial cleaning. Sodium dichloroisocyanurate
Chemical PropertiesChemical Formula: C₃Cl₂N₃NaO₃
Appearance: White crystalline powder or granules
Chlorine Content: Approximately 60% active chlorine
Solubility: Highly soluble in water, releasing free chlorine
When dissolved in water, SDIC slowly releases chlorine, which acts as a powerful disinfectant against bacteria, viruses, fungi, and algae.
Applications 1. Water DisinfectionDrinking water: SDIC tablets are widely used for purifying drinking water, especially in emergencies, disaster relief, and rural areas.
Swimming pools: It helps maintain clean, germ-free water by controlling bacteria and algae growth.
Cooling towers & industrial water systems: Prevents microbial contamination and biofilm formation.
Used for disinfecting medical equipment, hospital surfaces, and healthcare facilities.
Effective in sanitizing bathrooms, kitchens, and food preparation areas.
Widely adopted in military, disaster response, and humanitarian missions for quick water purification.
Acts as a bleaching and disinfecting agent in detergents.
Used in stain removal and odor control.
Applied in food and beverage processing industries for equipment sanitation.
Used in agriculture for disinfecting animal housing and equipment.
Plays a role in sterilizing laboratory instruments.
High stability: Long shelf life compared to liquid chlorine solutions.
Convenience: Easy to transport and use, especially in tablet form.
Cost-effective: Requires small quantities for effective disinfection.
Broad-spectrum action: Effective against bacteria, viruses, fungi, and spores.
While SDIC is highly effective, proper handling is essential:
Store in a cool, dry place away from moisture and organic materials.
Avoid direct contact with skin and eyes; it may cause irritation.
Do not mix with acids or other cleaning agents, as it can release toxic chlorine gas.
Follow manufacturer’s guidelines for safe dosage in water treatment.
