Chlorine Stabilizer -Cyanuric Acid 98% powder, gran or tablet
Product Description
Product Definition & Core Function
Cyanuric acid (C₃H₃N₃O₃), also called isocyanuric acid or pool conditioner. Purity ≥98% as white free-flowing powder. Its primary function is to protect free chlorine from UV degradation in outdoor pools, extending chlorine half-life from 1–2 hours to weeks. It does not disinfect but acts as a chlorine reservoir.
Chemical Properties
l CAS No.: 108-80-5
l Solubility: 0.27 g/100 mL water (25°C) – slow dissolving
l pH (1% solution): ~4.5 (weakly acidic)
l Not an oxidizer – non-flammable, stable solid.
l Transport: Not classified as dangerous goods under most regulations
Application Sub-segments
l Outdoor residential pools (maintain 30–50 ppm CYA)
l Commercial pools and water parks
l Spa/hot tubs (lower levels, as warm water accelerates chlorine release)
l Industrial cooling towers using chlorinated isocyanurates
l As raw material for TCCA and SDIC production
Comparison
Parameter | Cyanuric Acid | No Stabilizer |
Chlorine loss (sun) | <10% per day | >75% per hour |
Required free Cl level | 1–3 ppm | 0.5–1 ppm |
Over-stabilization risk | Yes (>100 ppm) | None |
Safety & Packaging
l Hazards: May cause eye irritation. Dust can be irritating to respiratory tract.
l Packaging: 25kg kraft paper bags with PE liner, 50kg PP woven bags, or 1kg retail jars.
l Handling: Avoid breathing dust; use dust mask during addition.

FAQ
l How to add? Pour directly into skimmer or pre-dissolve in warm water (not hot).
l How often to add? Typically once per season or after heavy rain/dilution. CYA does not evaporate.
l Can I use too much? Yes – >100 ppm reduces chlorine efficacy. Partial drain required.
l Difference from pool stabilizer liquids? Same chemical – powder is more economical.
