EDTA disodium salt solution 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 oxidation, thereby extending the shelf life of products like canned goods and dressings. In medicine, it is employed in chelation therapy to remove heavy metals like lead from the body. The solution is also utilized in cosmetics to stabilize formulations by preventing metal ion-induced degradation. In water treatment, it helps in controlling water hardness by sequestering calcium and magnesium ions. Additionally, it is used in laboratory settings as a component of buffer solutions to maintain pH stability during experiments.
