Tetrasodium Glutamatediacetate ●
TL;DR. This ingredient is a chelating agent that binds metal ions in water and formulas. It helps improve preservative performance, reduce discoloration, and support stability in cleansers, creams, and shampoos.
What does Tetrasodium Glutamatediacetate do in a cosmetic formula?
This ingredient is a chelating agent that binds metal ions in water and formulas. It helps improve preservative performance, reduce discoloration, and support stability in cleansers, creams, and shampoos.
Is Tetrasodium Glutamatediacetate clean?
From a clean beauty perspective, this ingredient is generally well accepted because it is low-irritation and not a common allergen. It is often used as a more biodegradable alternative to older persistent chelators.
Is Tetrasodium Glutamatediacetate sustainable?
This material is commonly made using a plant-derived amino acid feedstock, although the final molecule is chemically processed. It is readily biodegradable and has a stronger environmental profile than persistent chelating agents used for the same job.
Is Tetrasodium Glutamatediacetate COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic standards as a chelating agent when it meets origin and processing requirements. It fits Green Chemistry principles well through renewable feedstock potential, efficient use at low levels, and ready biodegradability.
How does Tetrasodium Glutamatediacetate work chemically?
The molecule is an aminopolycarboxylate with multiple sodium carboxylate groups that bind divalent and trivalent metal ions such as calcium, magnesium, and iron. It is typically used around 0.05 to 0.5% active, remains effective across roughly pH 3 to 13, and can improve preservation and color stability by reducing trace-metal catalysis.
