EDTA
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.
