What is tetrasodium glutamate diacetate?

This is a chelating agent derived from glutamic acid (an amino acid) that binds to metal ions in cosmetic formulations. It prevents metal-catalyzed degradation and supports formula stability, particularly in products containing botanical extracts or oils.

Is this ingredient a synthetic chemical?

Though derived from glutamic acid, tetrasodium glutamate diacetate is synthesized for cosmetic use. Its role is mineral sequestration, not preservation or conditioning, distinguishing it from preservatives or actives.
