White crystalline particle or white near white crystalline powder, odorless. It's easily soluble in water and nearly insoluble in ethanol.Edetate disodium is an important complexing agent for complexing metal ions and metal separation, this product is used as a color photographic materials bleach-fixing processing, and dyeing auxiliaries, fiber treatment agents, cosmetic additives , medicine, food, agriculture chemical trace fertilizer production, blood anticoagulant, complexing agents, detergents, stabilizers, synthetic rubber, a polymerization initiator and heavy metal quantitative analysis agent. In the reduction with a chlorinating SBR polymerization initiator system, EDTA disodium, as an integral part of an active agent, mainly for complexing iron ions, to control the polymerization reaction rate.
