EDTA Tetrasodium

High-Performance Water-Soluble Chelating Agent for Industrial & Specialty Applications

EDTA Tetrasodium, also known as Tetrasodium EDTA, is a highly water-soluble chelating and sequestering agent used to bind and control metal ions across a wide range of industrial and specialty applications. As the tetrasodium salt of Ethylenediaminetetraacetic Acid (EDTA), it is particularly suitable for alkaline and aqueous formulations where effective metal-ion control is required.

EDTA Tetrasodium is widely used in water treatment, detergents, industrial cleaning, textiles, pulp & paper, personal care, electroplating and specialty chemical formulations to support process stability and reduce unwanted metal-ion interference.

    Frequently Asked Questions

    What is EDTA Tetrasodium?

    EDTA Tetrasodium is the tetrasodium salt of Ethylenediaminetetraacetic Acid (EDTA). It is a water-soluble chelating agent used to bind and control metal ions in industrial and specialty formulations.

    What is EDTA Tetrasodium used for?

    It is commonly used in water treatment, detergents, industrial cleaning, textiles, pulp & paper, personal care, electroplating and specialty chemical formulations.

    What is the difference between EDTA Disodium and EDTA Tetrasodium?

    Both are sodium salts of EDTA. EDTA Tetrasodium contains four sodium ions and generally produces a more alkaline solution, while EDTA Disodium contains two sodium ions and is commonly used where a lower formulation pH is preferred.

    Is EDTA Tetrasodium water soluble?

    Yes. EDTA Tetrasodium has good water solubility, making it suitable for many aqueous formulations and industrial processes.

    Is EDTA Tetrasodium used in detergents?

    Yes. It is used in suitable detergent and cleaning formulations to help control hardness-causing and other metal ions.

    Do you supply EDTA Tetrasodium in bulk?

    Yes. Bulk supply and packaging options can be discussed based on quantity, application and customer requirements.
