Tetrasodium Glutamte Diacetate ●
TL;DR. This ingredient is a chelating agent that binds metal ions such as calcium, magnesium, and iron to improve formula stability, boost preservative performance, and reduce discoloration or rancidity triggers.
What does Tetrasodium Glutamte Diacetate do in a cosmetic formula?
This ingredient is a chelating agent that binds metal ions such as calcium, magnesium, and iron to improve formula stability, boost preservative performance, and reduce discoloration or rancidity triggers.
Is Tetrasodium Glutamte Diacetate clean?
From a clean-beauty perspective, it is generally well accepted because it is low-odor, low-sensitization, and not a common restricted-list concern. It is often used as a more biodegradable alternative to older synthetic chelators.
Is Tetrasodium Glutamte Diacetate sustainable?
This material is commonly made from renewable or fermentation-derived amino acid feedstocks combined with synthetic processing steps. It is readily biodegradable and has low persistence concerns compared with many legacy chelating agents.
Is Tetrasodium Glutamte Diacetate COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic when the grade and manufacturing route meet the standard’s criteria. Its profile fits Green Chemistry reasonably well because it supports low-use-level preservation, is readily biodegradable, and can be made partly from renewable feedstock.
How does Tetrasodium Glutamte Diacetate work chemically?
The molecule is an aminopolycarboxylate salt with multiple carboxylate groups that form stable complexes with metal ions in water-based formulas. Typical use levels are about 0.05 to 0.5%, with good performance across a broad pH range and strong compatibility in cleansers, emulsions, and preservation systems.
