Used in the synthesis of plasticizers and lubricants due to its long hydrocarbon chain, 1-undecanol contributes to improving flexibility and workability in polymers. It serves as an intermediate in the production of surfactants and emulsifiers for use in cosmetics and personal care products, providing emollient properties. Additionally, it finds application in fragrances as a mild, fatty-odor component in perfumes and flavorings. Its derivatization into esters enhances stability and performance in specialty formulations.
