Trichloroisocyanuric Acid (TCCA), commonly abbreviated as TCCA, is a versatile, stable organic compound with the chemical formula C₃Cl₃N₃O₃. It appears as a white crystalline powder or granular solid, highly soluble in water, and serves as a powerful source of active chlorine. Discovered in the mid-20th century, TCCA has become indispensable in industries requiring effective disinfection, bleaching, and sanitization. Its primary mechanism involves the slow release of hypochlorous acid (HOCl) upon dissolution in water, which is the most potent form of chlorine for killing bacteria, viruses, algae, and fungi.

In water treatment applications, Trichloroisocyanuric Acid is favored for its high chlorine content—typically 90% available chlorine—making it far more efficient than traditional bleach (sodium hypochlorite, ~10-15% chlorine). This efficiency translates to lower usage volumes and reduced shipping weights, critical for USA importers dealing with high freight costs. For swimming pools and spas, TCCA tablets (200g or 20g) provide long-lasting sanitization, stabilizing pH and preventing cyanuric acid buildup when used correctly at 30-50 ppm levels.

Beyond pools, TCCA excels in industrial wastewater treatment, where it oxidizes organic pollutants and controls odors. In the textile industry, it acts as a bleaching agent for cotton and synthetic fibers, ensuring uniform whitening without fabric degradation. Food processing plants rely on TCCA for surface disinfection of equipment and fruits/vegetables, compliant with FDA guidelines under 21 CFR 173.315 for no-rinse applications up to 200 ppm. Its stability—non-volatile and shock-resistant—makes it ideal for storage in humid USA warehouses, unlike dichloroisocyanuric acid (DCCA) which is less potent.

Technically, TCCA's structure features a cyanuric acid ring with three chlorine atoms, enabling controlled hydrolysis: C₃Cl₃N₃O₃ + H₂O → HOCl + byproducts. This results in minimal pH impact (slightly acidic, pH 2.5-4.0 in solution), preserving system balance. Purity grades vary: industrial 90% Cl, pharma-grade 99%+. At Shijiazhuang Standard IMP&EXP, we produce multi-grade TCCA via advanced chlorination of cyanuric acid, ensuring <1% impurities like heavy metals (<10 ppm Pb, As).

Historical data shows TCCA demand surging post-2020 due to pandemic-driven hygiene needs; global market projected at $1.2B by 2026 (Statista). USA consumption hits 50,000 MT/year, primarily for pools (40%) and water utilities (30%). Challenges include supply chain disruptions from China's dominance (80% production), but our Hebei facility mitigates this with 10,000 MT annual capacity.

Safety profile: UN 2468, Class 5.1 oxidizer. Handle with PPE; store below 40°C away from organics. EPA-registered for potable water (max 5 ppm residual Cl). Compared to calcium hypochlorite, TCCA has 50% less weight for equivalent chlorine, slashing logistics costs by 37% for trans-Pacific shipments.

Environmental benefits: Biodegradable cyanuric acid byproduct (breaks down via UV/hydrolysis), lower VOC emissions than gaseous chlorine. In aquaculture, TCCA treats fish ponds at 10 ppm, boosting survival rates by 25% per USDA studies. For your operations, switching to bulk TCCA granules reduces packaging waste by 40%.
