Tetrasodium Glutamate Diacetate (GLDA-Na₄), MF: C9H14NNaO8, MW: 287.2, is an environmentally friendly chelating agent produced by the condensation reaction of natural L-glutamic acid (a food-grade monosodium glutamate raw material) with chloroacetic acid. It forms stable, water-soluble complexes with various metal ions such as calcium, magnesium, iron and copper, and has a biodegradation rate of >90%, making it an ideal green alternative to traditional chelating agents such as EDTA and NTA.
