Ethylenediaminetetraacetic acid, disodium salt dihydrate, commonly known as Disodium EDTA or EDTA 2Na, stands as a pivotal chemical compound in numerous industrial and commercial sectors. At NINGBO INNO PHARMCHEM CO.,LTD., we specialize in delivering high-quality EDTA 2Na, a white crystalline powder renowned for its exceptional ability to chelate metal ions. This property makes it an indispensable agent for applications requiring the control and neutralization of metal impurities, ensuring enhanced stability and efficacy of end products.

Our EDTA 2Na is characterized by its superior purity and consistent quality, meeting rigorous industry standards. It typically exhibits a minimum purity of 99.0% (calculated to the dried substance), ensuring reliable performance in demanding applications. Key specifications include very low levels of impurities such as chloride (max 0.01%), sulfate (max 0.05%), heavy metals (as Pb, max 0.001%), and iron (Fe, max 0.001%). The chelating value is robust, typically 265 min, reflecting its strong binding capacity. Its pH in a 5% aqueous solution ranges from 4.0 to 6.0, indicating its suitability for various formulations. This white crystalline powder is highly soluble in water, forming stable complexes with a wide array of metal ions, making it a versatile choice across industries.

The utility of Disodium EDTA spans a vast array of applications. In water treatment, it is extensively used to reduce water hardness by sequestering calcium and magnesium ions, preventing scale formation in boilers and pipes. This makes it crucial for industrial water systems and laundry detergents, where it enhances the efficiency of soaps and cleaning solutions by preventing interference from hard water minerals. It also plays a vital role in inhibiting metal ion-catalyzed disproportionation of hydrogen peroxide in the pulp and paper industry, critical for chlorine-free bleaching processes. For agricultural uses, particularly in hydroponics, EDTA 2Na helps to solubilize iron ions, making them bioavailable to plants even in near-neutral pH soils where iron oxides are typically insoluble.

Beyond industrial water management, EDTA 2Na is a key component in personal care products. It is incorporated into detergents, liquid soaps, and shampoos as a sequestering agent, improving product stability by binding to metal ions that could otherwise cause degradation or discoloration. In cosmetics, it functions as a stabilizer to maintain product integrity and appearance over time. Its use extends to the photographic industry, where it acts as a bleaching fixer solution and dyeing aid, and in color film development.

In medical and laboratory settings, EDTA 2Na finds specialized uses. It is a common anticoagulant for blood samples, chelating calcium ions to prevent coagulation and preserve blood cell morphology for analysis. Dentists utilize EDTA solutions to remove the inorganic 'smear layer' from root canals, preparing them for obturation and aiding instrumentation. Biochemists and molecular biologists employ it to deactivate metal-dependent enzymes, suppress damage to biomolecules, and in complexometric titrations for analytical chemistry. It can also serve as a decalcifying agent in histopathology to facilitate tissue sectioning.

Our commitment at NINGBO INNO PHARMCHEM CO.,LTD. is to provide EDTA 2Na that ensures optimal performance and reliability for our clients. By preventing unwanted reactions catalyzed by metal ions, our product contributes to the longevity and effectiveness of diverse formulations. Its high chelating efficiency means smaller quantities can achieve significant results, offering cost-effectiveness for large-scale operations. We adhere to stringent quality control measures, ensuring that every batch meets the highest standards for purity and consistency.
