Dipotassium Edta ●
TL;DR. This ingredient is a chelating agent that binds trace metal ions in water and raw materials. It helps stabilize formulas, reduce discoloration, limit metal-catalyzed oxidation, and improve preservative performance.
What does Dipotassium Edta do in a cosmetic formula?
This ingredient is a chelating agent that binds trace metal ions in water and raw materials. It helps stabilize formulas, reduce discoloration, limit metal-catalyzed oxidation, and improve preservative performance.
Is Dipotassium Edta clean?
Clean-beauty frameworks often flag this ingredient because it is synthetic and poorly biodegradable, not because it is a common skin sensitizer at cosmetic levels. It is generally low-irritation in finished products, but its persistence profile creates restricted-list friction.
Is Dipotassium Edta sustainable?
This material is typically made from petrochemical-derived inputs and is not readily biodegradable. Its main sustainability concern is persistence in wastewater and the ability to keep metals mobile in aquatic systems.
Is Dipotassium Edta COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic standards. From a Green Chemistry perspective, it is a weak fit because it relies on nonrenewable feedstocks and has limited biodegradability, despite being effective at very low use levels.
How does Dipotassium Edta work chemically?
The molecule is an aminopolycarboxylate chelator supplied as a potassium salt, with multiple nitrogen and carboxylate donor sites that form stable complexes with calcium, magnesium, iron, and copper. Typical cosmetic use is about 0.05 to 0.2%, with broad pH utility and common co-formulation value in preservative support, color stability, and oxidation control.
