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).

Reduction of the carboxylic acid group yields oleyl alcohol. Ozonolysis of oleic acid is an important route to azelaic acid. The coproduct is nonanoic acid: [19] H 17 C 8 CH=CHC 7 H 14 CO 2 H + 4"O" → HO 2 CC 7 H 14 CO 2 H + H 17 C 8 CO 2 H. Esters of azelaic acid find applications in lubrication and plasticizers.
Miscibility (/ ˌ m ɪ s ɪ ˈ b ɪ l ɪ t i /) is the property of two substances to mix in all proportions (that is, to fully dissolve in each other at any concentration), forming a homogeneous mixture (a solution). Such substances are said to be miscible (etymologically equivalent to the common term "mixable").
The term alcohol originally referred to the primary alcohol ethanol (ethyl alcohol), which is used as a drug and is the main alcohol present in alcoholic drinks. The suffix -ol appears in the International Union of Pure and Applied Chemistry (IUPAC) chemical name of all substances where the hydroxyl group is the functional group with the ...
Selachyl alcohol is an organic compound with the formula HOCH 2 CH(OH)CH 2 OC 18 H 35. It is a colorless oil. Selachyl alcohol is a monoether formed by condensation of oleyl alcohol with one of the two primary alcohol sites of glycerol. Together with S-batyl alcohol and S-chimyl alcohol, S-selachyl alcohol is a component of some lipid membranes ...
U.S. wine sales continued a multiyear decline in 2024, which experts attribute to shifting demographics, health concerns, new competition and economic forces.
The results were difficult to interpret and not reliable, because of inaccurate results that were not standardised between laboratories. [ 25 ] Dilution has been used as a method to grow and identify bacteria since the 1870s, and as a method of testing the susceptibility of bacteria to antibiotics since 1929, also by Alexander Fleming.
