Edetate Disodium ●
TL;DR. This ingredient is a chelating agent that binds trace metal ions in water-based formulas. It helps stabilize color, scent, and viscosity, and it can improve preservative performance by reducing metal-driven degradation.
What does Edetate Disodium do in a cosmetic formula?
This ingredient is a chelating agent that binds trace metal ions in water-based formulas. It helps stabilize color, scent, and viscosity, and it can improve preservative performance by reducing metal-driven degradation.
Is Edetate Disodium clean?
From a clean beauty perspective, it is generally low-irritation at cosmetic use levels, but it faces clean-standard friction because of its persistence profile and synthetic manufacturing route. Many stricter frameworks flag it even though it is used at very low levels.
Is Edetate Disodium sustainable?
This material is typically synthetically produced from non-renewable feedstocks. Its main sustainability issue is limited biodegradability in conventional wastewater systems, which can contribute to environmental persistence.
Is Edetate Disodium COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic standards. Its Green Chemistry alignment is weak because it is synthetic, not readily biodegradable, and not based on renewable feedstocks, despite being effective at low concentrations.
How does Edetate Disodium work chemically?
The molecule is an aminopolycarboxylate chelator that can bind metal ions such as calcium, magnesium, iron, and copper through multiple coordination sites. Typical cosmetic use is about 0.01% to 0.2%, with broad pH compatibility and useful synergy in preservative systems and oxidation-sensitive formulas.
