Disodium EDTA anhydrous is a white odorless and tasteless crystalline powder, stable and non-deliquescent. It possesses strong chelating performance to bind calcium, magnesium, iron and other metal ions in water. Chemically stable under normal temperature; decomposes slowly under high temperature, strong acid or strong alkali conditions.
