  • Applications

    1,1'-(Oxydi-2,1-ethanediyl) dioctadecanoate (CAS 109-30-8) is a diester of stearic acid with an ethylene glycol linkage; in real-world applications it is typically used in cosmetics and personal care as an emollient, thickener, and pearlescent additive; it may also serve as a plasticizer or processing aid for polymers (notably PVC and related plastics) and as a slip lubricant in coatings and inks; in some household cleaning products it can act as a texture modifier and lubricity additive; and in broader industrial manufacturing it may function as a processing aid in lubricants and related formulations.
