  • Applications

    Ricinoleamidopropyltrimonium methosulfate (CAS 85508-38-9) is a cationic surfactant derived from castor oil commonly used in cosmetics and related industries. In cosmetics and personal care, it acts as a conditioning agent in shampoos and conditioners, providing slip and detangling performance. In household and cleansing products, it serves as a surfactant and emulsifier, improving oil–water dispersion and formulation stability in hand cleaners and body washes. In coatings and inks, it can function as a wetting and dispersing agent to enhance pigment dispersion and adhesion. In polymer and plastics processing, it can be used as a processing aid or surface-active additive to modify interfacial properties. In industrial manufacturing, it serves as a specialty surfactant to support controlled emulsification and formulation compatibility.
