Dipotassium EDTA is widely used in the pharmaceutical industry as a chelating agent to stabilize formulations by binding metal ions that could otherwise catalyze degradation. In cosmetics, it helps preserve product integrity by sequestering metals that might affect color, texture, or scent. In the food industry, it acts as a preservative, preventing oxidation and maintaining the quality of packaged foods. Additionally, it is employed in water treatment processes to control metal ion concentrations, ensuring water quality and preventing scaling in industrial systems. Its ability to bind calcium and magnesium ions also makes it a key component in medical applications, such as in anticoagulant solutions for blood collection tubes. It is also used in contact lens cleaning solutions to remove protein deposits and impurities. In the textile industry, it serves as an auxiliary in dyeing processes to condition fibers and prevent dye precipitation. Furthermore, it is an ingredient in metal cleaning formulations to remove rust and stains.
