Ethylenediaminetetraacetic Acid (EDTA)

Ethylenediaminetetraacetic Acid (EDTA), also known as edetic acid, is a white, odorless crystalline powder widely used as a chelating agent in various industries. With the chemical formula C₁₀H₁₆O₈N₂ and a molecular weight of 292.25, EDTA binds to metal ions such as Fe²⁺/Fe³⁺ and Ca²⁺, forming water-soluble complexes even at neutral pH. This property makes it essential in dissolving metal-containing scales and delivering iron ions in chemical processing, agriculture, water treatment, and hydroponics. In the pulp and paper industry, EDTA inhibits metal ions, especially Mn²⁺, from degrading hydrogen peroxide during bleaching. It also stabilizes colors in textiles by preventing metal ion impurities from altering dyed products. EDTA serves as an anticoagulant in blood analysis, preserving samples by chelating calcium ions. In personal care products like shampoos and cleaners, EDTA salts improve stability by sequestering metal ions. Additionally, EDTA acts as a preservative in foods, preventing catalytic oxidative discoloration caused by metal ions. Its versatility makes it indispensable in industrial, agricultural, and consumer applications.
