Frequently Asked Questions
Is sodium dichloroisocyanurate bleach?
Sodium dichloroisocyanurate (SDIC / NaDCC, CAS 2893-78-9) is a chlorine-releasing triazine-trione salt that acts as a sanitizing and bleaching agent. It releases available chlorine in solution and is used for bleaching textiles as well as for disinfection.
Is sodium dichloroisocyanurate the same as chlorine dioxide?
No. SDIC is a solid chlorine-releasing isocyanurate salt, whereas chlorine dioxide (ClO2) is a distinct gaseous oxidizer generated by separate chemistry. They are different compounds with different release mechanisms.
What is sodium dichloroisocyanurate used for?
SDIC is used as a chlorine-release agent in potable and wastewater treatment, swimming-pool and spa sanitation, dishwashing and detergent-sanitizer products, food-processing sanitation, and as a bleaching and wool shrink-resist agent in textiles.
How is sodium dichloroisocyanurate classified for shipping?
It ships as UN 2465 (SODIUM DICHLORO-S-TRIAZINETRIONE). DOT/IMDG documentation and the SDS must accompany shipments; review the SDS for storage and handling (keep away from incompatible materials) before ordering.
How is bulk SDIC supplied and priced?
SDIC is supplied as granules, powder, or tablets in drums or pails to water-treatment, sanitation, and cleaning manufacturers. Pricing depends on available-chlorine grade, form, and volume — request a bulk quote, CoA, and SDS.
What is the REACH and TSCA regulatory status of Sodium Dichloroisocyanurate (SDIC)?
Sodium Dichloroisocyanurate (SDIC) (CAS 2893-78-9) is subject to U.S. TSCA Inventory requirements; supplying it into the EU requires valid REACH registration ((EC) No 1907/2006). RawSource cannot verify a third-party supplier's registrations — buyers should require documented TSCA and REACH compliance for their jurisdiction and volume (EC 220-767-7).
