Hydrogenated Soybean Oil is a hydrogenated derivative of soybean oil (Glycine soja) created through the addition of hydrogen to unsaturated fatty acids, resulting in a more stable, semi-solid lipid with enhanced texturizing and emollient properties. In skincare formulations, it functions as an emollient and skin-conditioning agent, contributing to a smooth, velvety sensory profile and helping to form a barrier that reduces trans-epidermal water loss (TEWL), which supports long-lasting hydration and moisture retention. Its stability at room temperature and resistance to oxidation make it an excellent choice for products requiring consistent texture and extended shelf life, including creams, lotions, lip balms, and body butters where a rich, protective feel is desired. Because hydrogenation reduces the degree of unsaturation in the original oil, the ingredient is less prone to rancidity and helps improve the overall physical stability of emulsions and lipid phases.

In haircare, Hydrogenated Soybean Oil similarly serves as a conditioning and texture-enhancing component. When incorporated into shampoos, conditioners, hair masks, or styling treatments, it helps smooth the hair cuticle, improve manageability, and impart a silky, soft feel without weighing hair down seriously. The occlusive nature of the ingredient supports moisture retention on hair fibers and can help protect against environmental stressors that cause dryness and frizz when used in moderation. Its semi-solid state can also enhance the structural integrity of formulations targeted at dry, damaged, or frizzy hair, where nurturing and protective lipid layers are beneficial.
