Trisodiumethylenediamine Disuccinate ●
TL;DR. This ingredient is a chelating agent that binds trace metal ions in water-based formulas. It helps limit metal-catalyzed discoloration, odor changes, and preservative stress.
What does Trisodiumethylenediamine Disuccinate do in a cosmetic formula?
This ingredient is a chelating agent that binds trace metal ions in water-based formulas. It helps limit metal-catalyzed discoloration, odor changes, and preservative stress.
Is Trisodiumethylenediamine Disuccinate clean?
This ingredient is generally well tolerated at low use levels and is not a common fragrance allergen or sensitizer. Clean frameworks tend to view it favorably because it has limited restricted-list friction and a better biodegradability profile than older chelating systems.
Is Trisodiumethylenediamine Disuccinate sustainable?
This material is readily biodegradable, especially in its biodegradable stereochemical form, and has lower environmental persistence than conventional aminocarboxylate chelators. It is synthetically made, with feedstocks varying by supplier, so sourcing is not inherently agricultural or organic.
Is Trisodiumethylenediamine Disuccinate COSMOS-approved?
It is permitted for use in COSMOS-natural and COSMOS-organic formulations when compliant grades are used. Its Green Chemistry case is strong for a synthetic auxiliary because it is effective at low levels, water soluble, and designed for biodegradation.
How does Trisodiumethylenediamine Disuccinate work chemically?
The molecule is an aminocarboxylate ligand that wraps metal ions through nitrogen and oxygen donor atoms, forming water-soluble complexes with iron, copper, calcium, and magnesium. Typical use is about 0.05 to 0.3% active, it performs across mildly acidic to alkaline pH, and it is often paired with preservatives and antioxidants to reduce metal-driven instability.
