DISODIUM HYDROXYETHYLIMINODIACETATE

Description

Disodium Hydroxyethyliminodiacetate is a multifunctional chelating agent widely used in personal care and cosmetic formulations. This synthetic compound is derived from iminodiacetic acid and ethanol amine, resulting in a white, crystalline powder that readily dissolves in water. Its primary function is to sequester metal ions, particularly calcium and magnesium, which can interfere with the stability and efficacy of various skincare products.

In skincare formulations, Disodium Hydroxyethyliminodiacetate helps prevent discoloration, rancidity, and degradation of active ingredients by binding to metal ions. This property is especially valuable in products containing antioxidants or preservatives sensitive to metal-induced oxidation. Additionally, it enhances the foaming and cleansing properties of surfactants by softening water, making it a valuable ingredient in cleansers and shampoos.

The ingredient is considered safe for use in cosmetics at concentrations up to 2%. It exhibits good stability across a wide pH range and is compatible with most other cosmetic ingredients. While it primarily serves a technical function, Disodium Hydroxyethyliminodiacetate indirectly contributes to the overall efficacy and longevity of skincare products by maintaining their stability and preventing unwanted reactions.
