  • Applications

    Cetyl Dimethylbutyl Ether (CAS 185143-68-4) is used as a hydrophobic solvent and processing aid in specialty formulations; it can serve as a co-solvent for fragrance ingredients in perfumery and cosmetics; as a solvent in household and industrial cleaning products; it can function as a surfactant or emulsifier in coatings, inks, and related formulation systems; as a processing aid and lubricity additive in polymer and plastics processing, including as a plasticizer or flow modifier in certain systems; and may serve as an intermediate chemical in various industrial formulations, depending on regulatory and formulation constraints.
