Disodium EDTA (Ethylenediaminetetraacetic Acid Disodium Salt) – High-Efficiency Chelating Agent for the Detergent Industry

Disodium EDTA, commonly abbreviated as EDTA-2Na, is a water-soluble organic chelating agent with excellent solubility. It typically appears as a white crystalline powder, dissolves easily in water, and is sparingly soluble in organic solvents such as ethanol. In detergent formulations, it is not a cleaning ingredient but a core functional auxiliary. It plays a key role by chelating calcium and magnesium ions in water, and is often compounded with surfactants (e.g., LAS, SLES) and builders (e.g., 4A zeolite).
