Trisodium EDTA

What is Trisodium EDTA?

Trisodium EDTA is the trisodium salt of ethylenediaminetetraacetic acid, a synthetic molecule designed to capture metal ions. In cosmetics, it functions as a chelating agent, forming tight bonds with trace metals like iron, copper, and calcium found in water or ingredients. This action stops metals from catalyzing unwanted reactions such as oxidation, color changes, or breakdown of sensitive components. It appears in a wide range of products including moisturizers, cleansers, shampoos, and serums, especially water-based ones. By neutralizing metals, it bolsters formula stability, supports preservative performance without excess amounts, and helps keep textures smooth. This indirect protection aids overall product integrity, making it a staple in modern formulations for reliable performance.
