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 interfering with product stability and performance. In skincare, Tetrasodium EDTA plays a crucial role in preserving product integrity by inhibiting the growth of microorganisms and preventing color changes or rancidity caused by metal-induced oxidation.
The ingredient enhances the efficacy of preservatives and antioxidants in formulations, extending product shelf life. It also improves the foaming and cleansing properties of personal care products by softening water and reducing the negative effects of hard water minerals on skin and hair. Tetrasodium EDTA is particularly beneficial in products designed for use in areas with hard water.
While generally considered safe for topical use, Tetrasodium EDTA is typically used in low concentrations (0.05% to 0.1%) in skincare formulations. It's important to note that this ingredient is not metabolized by the body and is eventually excreted unchanged. Some concerns exist regarding its environmental impact due to its non-biodegradable nature, prompting ongoing research into more eco-friendly alternatives.
