Trisodium Ethylenediamine Disuccinate ●
TL;DR. This ingredient is a chelating agent that binds trace metal ions in water-based formulas. It helps protect color, fragrance, and oils from metal-catalyzed degradation, and it can improve preservative performance.
What does Trisodium Ethylenediamine Disuccinate do in a cosmetic formula?
This ingredient is a chelating agent that binds trace metal ions in water-based formulas. It helps protect color, fragrance, and oils from metal-catalyzed degradation, and it can improve preservative performance.
Is Trisodium Ethylenediamine Disuccinate clean?
From a clean-beauty perspective, it is generally well tolerated at typical cosmetic levels and is often used as a more biodegradable alternative to older chelators. It has low irritation concern and is not a common restricted-list issue.
Is Trisodium Ethylenediamine Disuccinate sustainable?
This material is synthetic, but its preferred stereochemical form is readily biodegradable and has lower environmental persistence than conventional aminocarboxylate chelators. Feedstocks may be petrochemical or partially bio-based depending on supplier, so sourcing can vary.
Is Trisodium Ethylenediamine Disuccinate COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic when it meets the standard’s approved-grade and processing requirements. Its strong biodegradability profile and low-use-level function fit Green Chemistry better than persistent chelating systems.
How does Trisodium Ethylenediamine Disuccinate work chemically?
The molecule is a water-soluble it salt with multiple carboxylate binding sites that complex iron, copper, calcium, and other metal ions. Typical use is about 0.05% to 0.3% active in the water phase, with good stability across common cosmetic pH ranges and best performance when fully dissolved before emulsification.
