  • Applications

    Octyl hydroxyethyl imidazoline (CAS 25575-42-2) is an amphiphilic surfactant/emulsifier used in cleaning systems and industrial and household detergents to improve emulsification, dispersion, and foaming stability. It is commonly employed as a component in metalworking fluids and industrial cleaners where it acts as a corrosion inhibitor and lubricant additive, helping to boost performance and service life of the fluid. In coatings and inks, it serves as an emulsifier and surface-treatment additive to enhance compatibility and adhesion. In cosmetics and personal care, it can be used as a surfactant and cleansing agent. In polymer and plastics processing, it may act as an emulsifier and processing stabilizer.
