Hydrogenated Dilinoleyl Alcohol

What is Hydrogenated Dilinoleyl Alcohol?

Hydrogenated Dilinoleyl Alcohol is a long-chain fatty diol created by hydrogenating dilinoleyl alcohol, derived from dimerized linoleic acid in plant oils such as safflower. This process saturates the molecule for stability, resulting in a waxy, emollient substance used primarily in skincare and lip products. It functions by depositing a thin, flexible film on the skin that enhances spreadability and lubricity, while aligning with the skin's lipid structure to minimize transepidermal water loss. As an emollient, it fills surface irregularities for smoother texture; as a skin conditioner, it supports barrier integrity without heaviness. Its high molecular weight ensures it stays on the surface, ideal for oil-free or lightweight formulas in creams, lotions, and balms.
