  • Applications

    Polyethylene Glycol Cetyl Ether (CAS 9004-95-9) is a nonionic surfactant used as an emulsifier and wetting agent, commonly positioned as an emollient in cosmetics and personal care. It also serves as a surface-active and emulsifying agent in household and cleaning products; in the industrial sector, it acts as a dispersant/emulsifier for polymer and pigment systems in coatings and inks; in plastics and related applications it can function as a processing aid to stabilize emulsions and dispersions.
