  • Applications

    Ethyl hydroxymethyl oleyl oxazoline (CAS 88543-32-2) is typically used as a functional additive for surface-active and stabilizing formulations. Typical applications include acting as a surfactant and emulsifier in coatings and inks, serving as a monomer or modifier for polymers/plastics and adhesives, and it may be used in cosmetics/personal care as a component that adjusts feel and surface lubricity. It can also function as an intermediate in the synthesis of oxazoline-containing polymers and may have potential in household products such as cleaners or thickeners, depending on formulation and local regulatory limits.
