EDTA disodium salt dihydrate is widely used in various industries due to its chelating properties. In the food industry, it acts as a preservative by binding metal ions that can catalyze spoilage, thereby extending the shelf life of products like canned foods, dressings, and sauces. In medicine, it is employed as an anticoagulant in blood collection tubes, preventing blood clotting by chelating calcium ions. Additionally, it is used in chelation therapy to treat heavy metal poisoning, as it binds to toxic metals like lead and mercury, facilitating their excretion from the body. In cosmetics, it stabilizes formulations by preventing metal-induced degradation and enhancing the effectiveness of preservatives. In water treatment, it helps control water hardness by sequestering calcium and magnesium ions, preventing scale formation in pipes and boilers. It is also utilized in industrial cleaning agents to remove metal ion deposits from surfaces. In analytical chemistry, it serves as a titrant in complexometric titrations to determine the concentration of metal ions in solutions. Its versatility and effectiveness make it a valuable compound across multiple applications.
