Tetrasodium EDTA

Tetrasodium EDTA is a water-soluble ingredient used as a chelating agent that sequesters metal ions and allow them to remain in formulas but lose their ability to react with other ingredients. This ability allows it to not only soften water, but preserve formulas as well by improving its stability when it is exposed to air and prevent microbial growth.
