    Frequently Asked Questions

    What is EDTA Disodium?

    EDTA Disodium is a disodium salt of ethylenediaminetetraacetic acid and is widely used as a chelating and sequestering agent for controlling metal ions.

    What is EDTA Disodium used for?

    It is used in water treatment, detergents, agriculture, textiles, pharmaceuticals, cosmetics, pulp and paper, electroplating and specialty chemical formulations.

    What is the difference between EDTA Acid and EDTA Disodium?

    EDTA Acid is the free-acid form, while EDTA Disodium is its disodium salt. EDTA Disodium generally offers better water solubility and is therefore useful in many aqueous formulations.

    Is EDTA Disodium water soluble?

    Yes. EDTA Disodium is a water-soluble form of EDTA and is commonly used in aqueous formulations and industrial processes.

    Is EDTA Disodium used in detergents?

    Yes. It can help control hardness-causing metal ions such as calcium and magnesium, supporting detergent performance in suitable formulations.

    Do you supply EDTA Disodium in bulk?

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