The 19% Tetrasodium EDTA is a water-soluble ingredient used as a chelating agent in cosmetics and personal care products because of its ability to sequester metal ions and allow them to remain in formulas but lose their ability to react with other ingredients. Orally the main purpose of it is to prevent the formation of calculus by reducing the deposition of calcium and magnesium on teeth. 19% Tetrasodium EDTA is offered by us for use in the various dental processes.
