Tetraacetic Acid ACSEDTA acid is a synthetic amino acid, which is used to treat lead and mercury poisoning. Sodium or calcium EDTA acid binds to metals, such as nickel, copper, and iron and make them unavailable to react with other ingredients in a product or compounds within the human body. Compounds that act in this way are known as chelating agents and thus EDTA acid is a chelating agent.
