  • Applications

    CAS 14048-77-2, dihydroxyethyl stearamine oxide is primarily used as a surfactant of the amine oxide class in formulated products. In cosmetics and personal care, it acts as a mild surfactant and conditioning agent in shampoos and cleansers. In household and industrial cleaning formulations, it aids wetting, emulsification, and foam control. In polymer and coating applications, it serves as an emulsifier and stabilizer for polymer latexes and as a dispersing agent to improve pigment dispersion in coatings and inks. In plastics processing, it can function as a compatibilizer or stabilizer for emulsion-based systems. These roles reflect its surfactant nature, and usage is subject to local regulations and formulation constraints.
