TCCA stands for Trichloroisocyanuric Acid which is an organic chlorine compound. TCCA-90 is used as a disinfecting agent in swimming pools or other industrial water storage bodies by providing free chlorine and protects this chlorine from sunlight. It also provides long-term effects in keeping the swimming pools free from bacteria and algae. 


We will be able to offer TCCA-90 granules of mesh (8-16) of Chinese origin in standard packing size of 50 kg plastic drums.

General Information


  • Disinfection of civil sanitation, swimming pools, industrial water pretreatments.
  • Oxidizing micro-biocide for cooling water systems.
  • Bleaching agent for cotton and chemical fabrics.
  • Animal husbandry and plant protection.
  • Anti-shrink agent for woolen materials.
  • Deodorizer in distilleries.
  • Preservative in horticulture and aquaculture industries. 

Usage Chemistry

After hydrolysis in water, TCCA will be converted to Hypochlorous Acid (HOCl), which has strong microbial activity. The hydrolysis by-product, cyanuric acid, acts as a chlorine stabilizer and prevents conversion of Hypochlorous Acid into Hypochlorite ion (OCl-) owing to sunshine and heat, which has low microbial activity.  


  • Cost effective and stable source of chlorine.
  • Easy to handle, ship, store and apply.
  • No white turbidity (as in case of bleaching powder).
  • Long duration of sterilizing effect.
  • Long Shelf Life.
