Tetrasodium Glutamate ●
TL;DR. This ingredient is primarily a biodegradable chelating agent. It binds metal ions in water and formulas, helping improve stability, preservative performance, clarity, and lather consistency.
What does Tetrasodium Glutamate do in a cosmetic formula?
This ingredient is primarily a biodegradable chelating agent. It binds metal ions in water and formulas, helping improve stability, preservative performance, clarity, and lather consistency.
Is Tetrasodium Glutamate clean?
From a clean-beauty perspective, it is generally well accepted because it has low irritation potential and is used as a modern alternative to less biodegradable chelators. Clean standards typically view it as low-friction when purity and processing residues are well controlled.
Is Tetrasodium Glutamate sustainable?
This material is commonly derived in part from plant-based feedstocks and is readily biodegradable. Its main sustainability advantage is that it reduces reliance on persistent chelating agents while performing effectively at low levels.
Is Tetrasodium Glutamate COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic standards when it meets the required manufacturing and purity criteria. It fits Green Chemistry principles better than many conventional chelators because it is readily biodegradable, effective at low dose, and can be made with renewable input streams.
How does Tetrasodium Glutamate work chemically?
This compound is an amino-acid-derived tetracarboxylate salt that complexes polyvalent metal ions such as calcium, magnesium, iron, and copper through multiple donor sites. It is commonly used around 0.05 to 0.5% active, works across a broad pH range of roughly 3 to 13, and can support preservation and oxidation control by reducing free metal ions.
