Sodium Ethylenediamine Disuccinate

TL;DR. This ingredient is a chelating agent that binds trace metal ions in water-based formulas. It helps protect color, scent, preservatives, and oxidation-prone ingredients from metal-catalyzed instability.

What does Sodium 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, scent, preservatives, and oxidation-prone ingredients from metal-catalyzed instability.

Is Sodium Ethylenediamine Disuccinate clean?

From a clean-beauty perspective, it is generally viewed as a low-irritation, modern chelator with fewer restricted-list concerns than older persistent options. It is used at low levels and is not a common fragrance allergen or sensitizer.

Is Sodium Ethylenediamine Disuccinate sustainable?

This material is designed to be readily biodegradable, especially when supplied as the common biodegradable stereoisomer. Its feedstock can vary by supplier, so the main sustainability question is whether the source is fossil-based or partly bio-based.

Is Sodium Ethylenediamine Disuccinate COSMOS-approved?

It is generally compatible with COSMOS-natural formulations when the raw material meets the standard’s manufacturing and impurity requirements. Its strong performance at low use levels and ready biodegradability fit Green Chemistry goals better than more persistent chelating systems.

How does Sodium Ethylenediamine Disuccinate work chemically?

The molecule is an aminopolycarboxylate salt with four carboxylate groups and two amine nitrogens, giving it strong binding capacity for calcium, magnesium, iron, copper, and other trace metals. Typical use is about 0.05% to 0.3%, and it performs best in aqueous systems across mildly acidic to alkaline pH ranges where its carboxylate groups remain available for metal binding.
