Tetrasodium Glutamate Diacetate ●
TL;DR. This ingredient is a chelating agent that binds metal ions in water-based formulas. It helps stabilize color, fragrance, preservatives, and surfactant systems by reducing metal-catalyzed reactions.
What does Tetrasodium Glutamate Diacetate do in a cosmetic formula?
This ingredient is a chelating agent that binds metal ions in water-based formulas. It helps stabilize color, fragrance, preservatives, and surfactant systems by reducing metal-catalyzed reactions.
Is Tetrasodium Glutamate Diacetate clean?
From a clean-beauty perspective, it is generally well accepted because it has low irritation and sensitization potential and is often used as an alternative to less biodegradable chelators. It has little restricted-list friction when used at normal cosmetic levels.
Is Tetrasodium Glutamate Diacetate sustainable?
This material is commonly made from renewable plant-based feedstocks through chemical processing. It is readily biodegradable and has a lower persistence profile than older aminocarboxylate chelators.
Is Tetrasodium Glutamate Diacetate COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic formulations when it meets the standard’s sourcing and processing requirements. Its renewable feedstock base, biodegradability, and low use levels fit Green Chemistry principles reasonably well.
How does Tetrasodium Glutamate Diacetate work chemically?
The molecule is an aminocarboxylate salt with several carboxylate sites that bind calcium, magnesium, iron, and other trace metals. Typical use levels are about 0.05% to 0.5%, and it remains effective across a broad pH range, including mildly acidic to alkaline formulations.
