Diethylenetriaminepentaacetic acid (DTPA) 40 % supplied by Global Optimals is a certified chelating agent with a 40 % concentration in an aqueous solution. DTPA belongs to the polyamino‑carboxylic acid family and is renowned for its resistance to oxidative degradation, making it especially suitable for processes that involve strong oxidants. In pulp bleaching, DTPA forms highly stable complexes with Fe³⁺, Cu²⁺ and Mn²⁺ ions, thereby suppressing the catalytic decomposition of hydrogen peroxide. This effect can reduce peroxide consumption by 10‑15 % and limit the formation of undesirable chlorinated by‑products. When introduced at 0.1‑0.3 % of the pulp weight, DTPA also mitigates corrosion of steel reactors and heat exchangers, extending equipment lifespan. Beyond the paper industry, DTPA is employed in water‑treatment schemes such as cooling‑tower blow‑down treatment, reverse‑osmosis pretreatment, and industrial wastewater polishing, where it sequesters trace heavy metals (e.g., Pb²⁺, Cd²⁺) into soluble complexes that are easier to remove. In pharmaceutical synthesis, DTPA acts as a ligand to stabilize transition‑metal catalysts and as a protective agent during the preparation of active pharmaceutical ingredients that are sensitive to metal‑catalyzed oxidation. The product should be stored in a dry, cool environment (15‑25 °C) away from direct sunlight to prevent hydrolysis. It is delivered in 25 kg drums together with complete technical documentation (TDS, SDS, COA), facilitating straightforward integration into existing process lines. The verified purity of 99.5 % ensures consistent performance and minimizes the risk of contaminating the final product. Technical support is available throughout the implementation phase, assisting with dosage optimization, bleaching process tuning, and water‑treatment system adjustments.

Store DTPA 40 % in a dry, well‑ventilated area away from direct sunlight and heat sources. Ensure the original packaging—typically plastic drums or containers—is tightly sealed to prevent moisture ingress and contamination. Under these conditions the product retains its performance for at least 12 months, but it is advisable to use it within a year of receipt. During handling wear protective gloves and goggles, avoid skin and eye contact, and provide local exhaust ventilation if needed.
