Disodium ethanoldiglycinate is a chelator that can also be found in a variety of household products including cleaning, water treatment and personal care products. The word chelator (pronounced "key-lay-tor") comes from the Greek word chele, or claw. Think of a chelator as a tiny claw that reaches out and grabs the minerals in soap scum or soils, to keep them from depositing on a surface. We use disodium ethanoldiglycinate in products to remove soap scum and mineral deposits that are caused by hard water. By binding to the soap scum or deposit, it allows them to be rinsed away.
