Diisostearyl Dimer Dilinoleate
What is Diisostearyl Dimer Dilinoleate?
Diisostearyl dimer dilinoleate is a synthetic ester produced by reacting isostearyl alcohol with dilinoleic acid, which forms from dimerizing linoleic acid sourced from vegetable oils like soybean or safflower. It belongs to the category of emollient esters commonly used in cosmetics, particularly anhydrous formulations such as lipsticks, lip glosses, and balms. In products, it works by creating a lightweight, non-greasy film on the skin or lips that enhances spreadability, imparts a smooth silky texture, and supports skin barrier function. This ingredient mimics natural skin lipids, helping to fill in surface irregularities for improved tactile properties. Its high molecular weight prevents deep penetration, focusing benefits on the outermost skin layers while maintaining product stability and shine in color cosmetics.
