  • Applications

    Oleyl hydroxyethyl imidazoline (CAS 21652-27-7) is commonly used as a cationic surfactant and conditioning/softening agent in cosmetics and personal care; it can function as an emulsifier and wetting agent in household cleaners and detergents; it serves as a functional additive in coatings and inks to improve wetting, dispersion and stability; in industrial applications it acts as a lubricity additive and corrosion inhibitor in metalworking fluids and other lubricants; it may also serve as a processing aid or surfactant in polymer and plastics formulations, and can be used as an intermediate in chemical synthesis, depending on formulation and regulatory constraints.
