Tetrasodium Glutamate Diacetate
What is Tetrasodium Glutamate Diacetate?
Tetrasodium Glutamate Diacetate is the tetrasodium salt of a diacetic acid derivative from L-glutamic acid, a naturally occurring amino acid. In cosmetics, it functions as a chelating agent, capturing trace metal ions such as calcium, iron, and magnesium from water or ingredients. These metals can trigger oxidation, leading to product instability, color shifts, or reduced effectiveness. By forming inert complexes, it maintains formula integrity across cleansers, lotions, shampoos, and other personal care items. Recognized for its biodegradability, it offers an eco-friendlier option compared to persistent chelators. Authoritative reviews confirm its mild profile, with low potential for skin or eye irritation in typical use levels found in leave-on and rinse-off products.
