TRISODIUM EDTA

Description

Trisodium EDTA (Ethylenediaminetetraacetic Acid) is a versatile chelating agent widely used in skincare and cosmetic formulations. This synthetic compound effectively binds to metal ions, particularly calcium and magnesium, preventing them from interfering with product stability and performance. In skincare, Trisodium EDTA serves multiple functions, primarily as a preservative enhancer and antioxidant booster.

Its ability to sequester metal ions helps maintain product integrity by inhibiting microbial growth and oxidation processes. This results in extended shelf life and improved efficacy of active ingredients. Trisodium EDTA also enhances the foaming and cleansing properties of surfactants, making it valuable in cleansers and shampoos.

In formulations, Trisodium EDTA is typically used at concentrations between 0.05% to 0.1%. It's particularly beneficial in products containing natural ingredients or those exposed to hard water. While generally considered safe for topical use, some individuals with sensitive skin may experience mild irritation. It's important to note that Trisodium EDTA is not readily biodegradable, raising environmental concerns about its long-term impact on aquatic ecosystems.
