Fatty alcohols: Production route
Natural versus synthetic: two routes to almost the same molecule
What this tab covers How it is made: the main production routes or, for product families, the main product types and technologies, compared on share of supply, inputs per tonne, plant scale, yield, co-products and unit cost.Two families compete. Oleochemical (natural) alcohols come from hydrogenating methyl esters or fatty acids of palm kernel and coconut oil, giving even-numbered linear chains. Synthetic alcohols come from ethylene: Ziegler chain growth gives linear alcohols similar to natural ones, while oxo (hydroformylation) of olefins gives partly branched alcohols. Which route wins depends on the lauric oil price against ethylene: when palm kernel oil spikes, synthetic producers gain share.
Routes compared
| Route | Share of supply | Inputs per tonne | Typical scale | Yield | Co-products | Unit cost |
|---|---|---|---|---|---|---|
| Methyl ester hydrogenation (oleo) | majority of oleo alcohol, about two-thirds of world capacity together with acid hydrogenation (indicative, basis: GlobalData company shares) | about 1.1-1.2 t lauric oil, about 0.02-0.03 t hydrogen per t alcohol (indicative) | 60-200 kt a year (Apical Dumai 130 kt, Unilever Sei Mangkei 120 kt, 2025) | high on chain (indicative) | glycerine about 0.1 t per t oil; C8-C10 and C16-C18 co-cuts | lauric oil is 70-80% of cost (indicative); fatty alcohol about $2,500-3,000/t in 2025-26 |
| Fatty acid hydrogenation (oleo) | smaller share of oleo alcohol (indicative) | about 1.1 t fatty acids per t (indicative) | 30-100 kt a year | high | water | similar to ester route (indicative) |
| Ziegler alcohols (synthetic, linear) | part of Sasol's 14% share (indicative) | about 1 t ethylene per t alcohol plus aluminium (indicative) | 100-300 kt a year | broad chain distribution | alumina (high-purity) | tracks ethylene (indicative) |
| Oxo and SHOP alcohols (synthetic, partly branched) | Shell 11% plus part of Sasol (indicative) | about 0.9 t olefins and syngas per t (indicative) | 100-500 kt a year | high | heavy ends | tracks ethylene and gas (indicative) |
How each route works
Methyl ester hydrogenation (oleo)Palm kernel or coconut oil is converted to methyl esters, fractionated, then hydrogenated in fixed-bed reactors; methanol is recycled.
renewable carbon; exposed to lauric oil swings and deforestation risk
GlobalData presentation, Fedepalma International Conference, Aug 2025; surfactants tile; indicative Fatty acid hydrogenation (oleo)Distilled fatty acids are hydrogenated directly, often in slurry reactors.
uses split acids from integrated plants; harsher catalyst conditions
indicative Ziegler alcohols (synthetic, linear)Ethylene grows chains on triethylaluminium; oxidation and hydrolysis give linear even-numbered alcohols (Sasol Lake Charles, indicative).
independent of palm; fossil carbon
GlobalData presentation, Fedepalma International Conference, Aug 2025; indicative Oxo and SHOP alcohols (synthetic, partly branched)Linear olefins (from Shell's SHOP process or Fischer-Tropsch) are hydroformylated with syngas to detergent-range alcohols (Shell Neodol, Sasol, indicative).
low cost in the US Gulf; branched chains change biodegradation and performance
GlobalData presentation, Fedepalma International Conference, Aug 2025; indicative Unit economics are indicative ranges from the sources named; costs move with feedstock and energy prices, plant size and region.
