Tetrasodium Glutamate Diacetate

Tetrasodium glutamate diacetate is a biodegradable chelating agent that serves as an alternative to EDTA.

This amino acid-based chelating agent works by chemically capturing heavy metal ions and disarming their harmful effects. Heavy metal ions are naturally present in water and can have negative effects on the other ingredients present in skincare products, as well as on the skin itself.

Therefore, whenever non-distilled water is used to manufacture skincare products, a chelating agent, such as tetrasodium glutamate diacetate, is needed to protect the product.
