Oleyl alcohol / ˈ oʊ l i ˌ ɪ l, ˈ oʊ l i əl /, [1] or cis-9-octadecen-1-ol, is an unsaturated fatty alcohol with the molecular formula C 18 H 36 O or the condensed structural formula CH 3 (CH 2) 7 −CH=CH−(CH 2) 8 OH. It is a colorless oil, mainly used in cosmetics.
Most fatty alcohols in nature are found as waxes, which are esters of fatty acids and fatty alcohols. [1] They are produced by bacteria, plants and animals for purposes of buoyancy, as source of metabolic water and energy, biosonar lenses (marine mammals) and for thermal insulation in the form of waxes (in plants and insects).
