Production and occurrence
Most fatty alcohols in nature are found as waxes which are esters with fatty acids and fatty alcohols.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).Fatty alcohols were unavailable until the early 1900s. They were originally obtained by reduction of wax esters with sodium by the Bouveault–Blanc reduction process. In the 1930s catalytic hydrogenation was commercialized, which allowed the conversion of fatty acid esters, typically tallow, to the alcohols. In the 1940s and 1950s, petrochemicals became an important source of chemicals, and Karl Ziegler had discovered the polymerization of ethylene. These two developments opened the way to synthetic fatty alcohols.

From natural sources
The traditional sources of fatty alcohols have largely been various vegetable oils and these remain a large-scale feedstock. Animal fats (tallow) were of historic importance, particularly whale oil, however they are no longer used on a large scale. Tallows produce a fairly narrow range of alcohols, predominantly C16–C18, the chain lengths from plant sources are more variable (C6–C24) making them the preferred source. The alcohols are obtained from the triglycerides (fatty acid triesters), which form the bulk of the oil. The process involves the transesterification of the triglycerides to give methyl esters which are then hydrogenated to give the fatty alcohols.Higher alcohols (C20–C22) can be obtained from rapeseed oil or mustard seed oil. Midcut alcohols are obtained from coconut oil (C12–C14) or palm kernel oil (C16–C18)
