Ethylenediamine Disuccinate ●
TL;DR. This ingredient is a chelating agent that binds trace metal ions such as iron, copper, calcium, and magnesium. It helps protect formula stability, reduce discoloration and off-odors, support preservative systems, and improve performance in hard water.
What does Ethylenediamine Disuccinate do in a cosmetic formula?
This ingredient is a chelating agent that binds trace metal ions such as iron, copper, calcium, and magnesium. It helps protect formula stability, reduce discoloration and off-odors, support preservative systems, and improve performance in hard water.
Is Ethylenediamine Disuccinate clean?
Clean-beauty frameworks generally view it as a favorable chelator because it has low irritation potential and addresses the persistence concerns associated with older chelating agents. It is not a common restricted-list flashpoint when used at normal cosmetic levels.
Is Ethylenediamine Disuccinate sustainable?
This material is typically synthetic, with feedstocks that may be petrochemical or partly bio-based depending on supplier. Its main sustainability strength is ready biodegradability, especially for the biodegradable stereochemical grade used in personal care.
Is Ethylenediamine Disuccinate COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic when the supplied grade and manufacturing route meet the standard’s requirements. From a Green Chemistry perspective, it scores well for biodegradability and efficient metal binding, though its sourcing is not always fully renewable.
How does Ethylenediamine Disuccinate work chemically?
The molecule is an aminopolycarboxylate built around a diamine core with multiple carboxylate binding sites, allowing stable soluble complexes with transition and hardness-metal ions. Typical use levels are often about 0.05% to 0.2% active in the water phase, and it is most useful in systems where trace metals can affect oxidation, color, fragrance, or preservative robustness.
