  • Applications

    Majonoside R 2 is a triterpenoid saponin glycoside that exhibits natural surfactant and emulsifying properties. In practice, it may be used as a mild surfactant/emulsifier in cosmetics and personal care formulations, and as a functional ingredient in household cleaning products. It can serve as an additive or processing aid in industrial formulations requiring surface activity, and may function as an eco-friendly component in coatings and inks. In pharmaceutical and agrochemical R&D, Majonoside R 2 is often evaluated as an intermediate or excipient for glycoside derivatives and as an adjuvant or formulation aid in agrochemical products, subject to local regulations and formulation limits.
