Trisodium Edta ●
TL;DR. This ingredient is a chelating agent used to bind trace metal ions in water-based formulas. It helps protect color, fragrance, texture, and preservative performance by reducing metal-driven instability.
What does Trisodium Edta do in a cosmetic formula?
This ingredient is a chelating agent used to bind trace metal ions in water-based formulas. It helps protect color, fragrance, texture, and preservative performance by reducing metal-driven instability.
Is Trisodium Edta clean?
Clean-beauty frameworks often flag or prohibit it because it is synthetic, persistent in water systems, and can increase the mobility of metal ions. Skin irritation is usually low at typical cosmetic use levels.
Is Trisodium Edta sustainable?
This material is made through conventional synthetic chemistry rather than direct plant or mineral sourcing. Its main sustainability drawback is poor ready biodegradability and persistence in aquatic environments.
Is Trisodium Edta COSMOS-approved?
It is generally not permitted under COSMOS-natural or COSMOS-organic standards. From a Green Chemistry lens, it scores weakly because it is not readily biodegradable and is not based on renewable feedstocks, even though it can improve formula stability at very low levels.
How does Trisodium Edta work chemically?
This molecule is a synthetic aminopolycarboxylate chelator with multiple carboxylate and amine donor sites that form stable complexes with calcium, magnesium, iron, and copper ions. Typical use levels are about 0.05% to 0.2%, and it is broadly effective across common cosmetic pH ranges in water-containing systems.
