Tetrasodium EDTA
What is Tetrasodium EDTA?
Tetrasodium EDTA is a chelating agent commonly used in personal care products. It is synthesized by the reaction of ethylenediaminetetraacetic acid (EDTA) with sodium. This process helps in creating a compound that binds to metal ions.
In cosmetics and skincare, Tetrasodium EDTA is valued for its ability to stabilize formulas and enhance product shelf life by preventing metals from reacting with other ingredients. The health evidence suggests it is generally considered safe for topical use, though some advocate for caution due to potential skin irritation in sensitive individuals.
When you see Tetrasodium EDTA on a label, it's generally used to improve the stability and effectiveness of the product by controlling metal availability.
Commonly found in: Body Lotion, Skin Care, Hair Care
