Glutamate Diacetate ●
TL;DR. This ingredient is a chelating agent that binds metal ions such as calcium, magnesium, iron, and copper. It improves formula stability, boosts preservative performance, and helps surfactant systems perform better in hard water.
What does Glutamate Diacetate do in a cosmetic formula?
This ingredient is a chelating agent that binds metal ions such as calcium, magnesium, iron, and copper. It improves formula stability, boosts preservative performance, and helps surfactant systems perform better in hard water.
Is Glutamate Diacetate clean?
From a clean-beauty perspective, this ingredient is generally well-tolerated and not a common restricted-list issue. It is often used as a readily biodegradable chelator when brands want a lower-residue option than older petrochemical chelating systems.
Is Glutamate Diacetate sustainable?
This material is commonly made from an amino-acid-derived feedstock and is designed to biodegrade readily in wastewater conditions. Its main sustainability advantage is strong metal-binding performance at low use levels with lower persistence than many legacy chelators.
Is Glutamate Diacetate COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic standards when it meets the standard’s sourcing and processing criteria. It aligns well with Green Chemistry through biodegradability, low use concentration, and partial renewable carbon sourcing, though its manufacture still involves industrial chemical processing.
How does Glutamate Diacetate work chemically?
The molecule is an aminocarboxylate chelator with multiple carboxylate groups that form stable complexes with polyvalent metal ions. Typical active use levels are about 0.05 to 0.5%, and it remains effective across a broad pH range, including acidic cleansers and alkaline soap-based systems.
