  • Applications

    Lauryldiethanolamine (CAS 1541-67-9) is commonly used as a nonionic surfactant and emulsifier and as a key intermediate for the synthesis of more complex surfactants and quaternary ammonium compounds employed in detergents and specialty cleaners. In cosmetics and personal care, it functions as a surfactant, foaming agent, and emulsion stabilizer in shampoos and cleansers. In household and industrial cleaning formulations, it aids wetting, emulsification, and soil removal. In coatings, inks, and polymer formulations, it serves as a dispersing and leveling agent, helping pigment stability and formulation uniformity. It may also be used as a processing aid or additive in polymer and lubricant formulations and as a foundation for further surfactant derivatization, subject to local regulations and formulation limits.
