(9Z)-octadecen-1-ol is a long-chain fatty alcohol characterized by the presence of octadecanol with a double bond at position 9, specifically in the Z-geometric isomer configuration. This compound serves a dual role as a nonionic surfactant and a metabolite. It belongs to the category of long-chain primary fatty alcohols and is classified as a fatty alcohol with the designation 18:1. Oleyl alcohol, also known as cis-9-octadecen-1-ol, is a natural product discovered in Ruvettus pretiosus and Bombus hortorum. This unsaturated fatty alcohol, with the molecular formula C18H36O, is a colorless oil widely employed in cosmetic applications. It is primarily obtained through the hydrogenation of oleic acid esters using the Bouveault–Blanc reduction method. This process selectively reduces esters without affecting the C=C double bond, and the necessary oleate esters are sourced from various materials, including beef fat, fish oil, and olive oil. Oleyl alcohol finds versatile applications in the cosmetic industry, functioning as a nonionic surfactant, emulsifier, emollient, and thickener in products such as skin creams, lotions, shampoos, and hair conditioners. Additionally, it has been explored for its potential as a carrier for delivering medications through the skin or mucous membranes, including the lungs. The compound's multifunctional properties contribute to its widespread use in cosmetic formulations and ongoing research into its pharmaceutical applications.
