For scenarios demanding the strongest and fastest disinfection power (highest available chlorine), choose the Anhydrous form.
For general-purpose water treatment like swimming pools, where a good balance of effective chlorine and quick dissolution is key, the Dihydrate is the most versatile and common choice.
If long-term storage stability or a more controlled chlorine release is the primary concern, the Trihydrate is the most suitable option.

Sodium Dichloroisocyanurate (SDIC): Product Form Selection Guide
| Form | Key Characteristics | Typical Applications & Advantages |
| Granules | Medium dissolution rate, easier to handle and dose than powder. | Versatile for water treatment: Ideal for swimming pools, industrial cooling water, and agricultural disinfection where controlled, manual or feeder-based dosing is used. |
| Tablets | Slow, controlled dissolution; pre-measured dosage, very convenient. | Perfect for maintenance dosing: Best for small to medium pools, spas, toilet tanks, or any application requiring long-lasting, hassle-free chlorination with minimal handling. |
| Powder | Fastest dissolution rate, highest surface area. | For rapid disinfection & shock treatment: Used in drinking water emergency treatment, surface disinfection, and scenarios needing immediate high chlorine concentration or quick dissolution in solution making. |
What is Sodium Dichloroisocyanurate Used for?
For Water Treatment: SDIC is widely used to disinfect swimming pool water, industrial cooling water, and for emergency drinking water purification.
In Public & Household Sanitation: SDIC serves as an effective disinfectant for surfaces, utensils, and environments in hospitals, restaurants, and homes.
In Agriculture & Aquaculture: SDIC is applied for disinfecting ponds, livestock areas, and in preventing crop diseases.
For Industrial Bleaching: SDIC functions as a bleaching agent in the textile industry and for wool shrink-proofing.
FAQ of Sodium Dichloroisocyanurate
When used correctly at recommended dilutions, it is safe and effective. However, it is an irritant and can be harmful if ingested, inhaled, or in direct contact with skin or eyes at high concentrations. Always follow the safety instructions on the label.
Yes, it is a type of chlorine-based bleaching agent. Its primary function is disinfection, but the active chlorine released also effectively bleaches stains and whitens materials, which is why it’s used in textile bleaching.
The available chlorine content varies by product form (typically 55-65%). This key specification determines the disinfecting strength and dosage. Please refer to our product specifications or contact us for the exact data of the grade you need.
