Diisopropyl Dimer Dilinoleate
What is Diisopropyl Dimer Dilinoleate?
Diisopropyl Dimer Dilinoleate is a synthetic ester produced by reacting dilinoleic acid—a dimerized linoleic acid from vegetable oils—with isopropanol. This clear, oily liquid serves as an emollient in cosmetics, appearing in lipsticks, hair conditioners, moisturizers, and anhydrous formulas. It functions by spreading evenly to coat skin and hair shafts, reducing surface friction for improved glide and texture. By mimicking sebum's lipid profile, it fills microscopic gaps on the skin's surface, enhancing suppleness without a heavy residue. Its branched chain structure boosts oil solubility and product stability, while supporting barrier function to limit transepidermal water loss in formulations.
