EDTA (Ethylenediamine Tetraacetic Acid) is a powerful chelating agent that binds with metal ions such as calcium, magnesium, iron, and copper to form stable, water-soluble complexes. It is widely used to control metal ion activity, prevent scale formation, and stabilize formulations in a variety of industrial, pharmaceutical, cosmetic, and agricultural applications.
EDTA is available in acid form as well as sodium salt forms (EDTA-2Na, EDTA-4Na), each suitable for specific pH ranges and uses.
