  • Applications

    1-Ethyl-1-(2-hydroxyethyl)-2-(15-methylhexadecyl)-4,5-dihydro-1h-imidazol-1-ium ethyl sulfate (CAS 67633-57-2) is an imidazolium-based salt with a long-chain cation bearing a hydroxyethyl group, paired with an ethyl sulfate counterion. It functions as a surface-active compound and dispersant suitable for use in various emulsions and personal care or household formulations. In industry, it can serve as an ionic-liquid-like solvent or reaction medium for chemical processing. In coatings and inks, it can aid pigment dispersion and improve surface wetting as a surface-active additive. In polymers/plastics processing, it can be used as a processing aid and as a softening or stabilizing agent during manufacturing. Additionally, owing to its surface-active character and long hydrophobic chain, it may act as a lubricant additive or corrosion inhibitor in industrial lubricant systems, subject to local regulations and formulation limits.
