Disodium undecylenamido MEA-sulfosuccinate is a mild anionic surfactant derived from undecylenic acid and sulfosuccinate chemistry. It is widely used in personal care formulations such as shampoos, facial cleansers, and body washes due to its gentle cleansing and foaming properties. The ingredient is particularly valued for its mildness, making it suitable for sensitive skin and baby care products. It also contributes to enhanced lather and product stability in formulations.
