Disodium EDTA *Purity 93% ●
TL;DR. This ingredient is a chelating agent that binds trace metal ions in water-based formulas. It helps stabilize color, scent, texture, and preservative performance by reducing metal-catalyzed oxidation and discoloration.
What does Disodium EDTA *Purity 93% 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, texture, and preservative performance by reducing metal-catalyzed oxidation and discoloration.
Is Disodium EDTA *Purity 93% clean?
From a clean-beauty perspective, this ingredient has friction because many restricted lists flag it for persistence and aquatic concerns rather than for routine skin irritation. It is generally well tolerated on skin at typical cosmetic levels, but its environmental profile keeps it out of stricter natural standards.
Is Disodium EDTA *Purity 93% sustainable?
This material is synthetically produced, typically from non-renewable feedstocks, and it is not readily biodegradable under standard screening conditions. Its persistence in wastewater and ability to keep metals soluble are the main sustainability concerns.
Is Disodium EDTA *Purity 93% COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic standards. Its poor biodegradability and fossil-derived synthetic route make it a weak fit with Green Chemistry priorities, even though it is effective at very low use levels.
How does Disodium EDTA *Purity 93% work chemically?
This molecule is an aminopolycarboxylate chelator that forms strong 1:1 complexes with divalent and trivalent metal ions such as calcium, magnesium, iron, and copper. Typical cosmetic use is about 0.05% to 0.2%, it is broadly pH-stable, and the stated 93% assay usually means the balance is water and inorganic process salts defined by the supplier specification.
