Tetrasodium Ethylenediamine Disuccinate ●
TL;DR. This ingredient is a chelating agent that binds metal ions in water-based formulas. It helps improve formula clarity, preservation robustness, color stability, and performance in hard water.
What does Tetrasodium Ethylenediamine Disuccinate do in a cosmetic formula?
This ingredient is a chelating agent that binds metal ions in water-based formulas. It helps improve formula clarity, preservation robustness, color stability, and performance in hard water.
Is Tetrasodium Ethylenediamine Disuccinate clean?
Clean-beauty frameworks generally view it as a well-tolerated alternative to older persistent chelators. It has low sensitization concern at typical use levels and is not a common restricted-list issue.
Is Tetrasodium Ethylenediamine Disuccinate sustainable?
This material is designed to be readily biodegradable, which gives it a stronger environmental profile than more persistent chelating agents. It is usually made through chemical synthesis, with feedstock origins varying by supplier.
Is Tetrasodium Ethylenediamine Disuccinate COSMOS-approved?
It is generally compatible with COSMOS-natural formulations when the specific grade meets supplier and certification requirements, but it is not an agricultural organic ingredient. From a Green Chemistry perspective, its strongest fit is high chelation efficiency at low use levels and ready biodegradability.
How does Tetrasodium Ethylenediamine Disuccinate work chemically?
The molecule is a water-soluble aminopolycarboxylate salt that complexes calcium, magnesium, iron, and other trace metals. Typical use is about 0.05% to 0.5% active, with best chelation performance in mildly acidic to alkaline systems and broad compatibility in rinse-off and leave-on water phases.
