  • Applications

    Distearyl Ether (CAS 6297-03-6) is a lipophilic nonionic ether with two stearyl groups, primarily used as a solvent and nonionic surfactant in cosmetic and personal care formulations to improve slip and texture. It may also function as a plasticizer or lubricating component in polymer systems, coatings, and adhesives. In industrial manufacturing, it can serve as a processing solvent and as an intermediate in chemical synthesis; it is also evaluated for cleaning applications due to its high lipophilicity. In coatings/inks and adhesives contexts, it may be considered as a plasticizer or processing aid where a lipophilic solvent is advantageous.
