Tetrasodium EDTA

Description

Tetrasodium EDTA (Ethylenediaminetetraacetic acid) is a versatile chelating agent widely used in skincare and cosmetic formulations. This synthetic compound effectively binds to metal ions, preventing them from interacting with other ingredients or the skin. Its primary function is to enhance product stability and maintain the efficacy of active ingredients.

In skincare, Tetrasodium EDTA serves multiple purposes. It acts as a preservative booster, working synergistically with other preservatives to inhibit microbial growth and extend product shelf life. By sequestering metal ions, it helps prevent oxidation and discoloration of formulations, ensuring consistent product appearance and performance. Additionally, Tetrasodium EDTA can improve the foaming and cleansing properties of surfactant-based products.

This ingredient is particularly beneficial in hard water areas, as it neutralizes the effects of calcium and magnesium ions that can interfere with product efficacy. Tetrasodium EDTA is generally considered safe for use in cosmetics at concentrations up to 2%. However, it's important to note that while it's effective in product formulation, it does not provide direct skin benefits and is primarily used for its functional properties in maintaining product integrity.
