TETRAHYDROXYETHYL ETHYLENEDIAMINE
Description
Tetrahydroxyethyl ethylenediamine, also known as THEED, is a versatile chelating agent widely used in skincare and cosmetic formulations. This synthetic compound is characterized by its ability to form stable complexes with metal ions, particularly calcium and magnesium. THEED's molecular structure consists of an ethylenediamine core with four hydroxyethyl groups attached, providing excellent water solubility and compatibility with various skincare ingredients.
In skincare products, THEED serves multiple functions. Primarily, it acts as a preservative booster, enhancing the efficacy of antimicrobial agents by sequestering metal ions that can interfere with their performance. This property contributes to improved product stability and extended shelf life. Additionally, THEED helps prevent the formation of soap scum and mineral deposits in cleansing formulations, ensuring optimal product performance in hard water conditions.
THEED is generally considered safe for use in cosmetics and is approved by regulatory bodies worldwide. Its low irritation potential makes it suitable for inclusion in a wide range of skincare products, including cleansers, toners, and moisturizers. The ingredient's ability to improve product stability and enhance the efficacy of other components makes it a valuable addition to many skincare formulations.
