Oleyl alcohol /ˈoʊliˌɪl, ˈoʊliəl/, or cis-9-octadecen-1-ol, is an unsaturated fatty alcohol with the molecular formula C18H36O or the condensed structural formula CH3(CH2)7-CH=CH-(CH2)8OH.
Oleyl alcohol is a colorless oil, mainly used in cosmetics.
Oleyl alcohol can be produced by the hydrogenation of oleic acid esters by Bouveault–Blanc reduction, which avoids reduction of the C=C group (as would occur with usual catalytic hydrogenation).
The required oleate esters are obtained from beef fat, fish oil, and, in particular, olive oil (from which it gains its name).
The original procedure was reported by Louis Bouveault in 1904 and subsequently refined.
Oleyl alcohol has uses as a nonionic surfactant, emulsifier, emollient and thickener in skin creams, lotions and many other cosmetic products including shampoos and hair conditioners.
Oleyl alcohol has also been investigated as a carrier for delivering medications through the skin or mucus membranes; particularly the lungs
Oleyl alcohol also is a precursor for the preparation of its sulfuric ester derivatives, which are used in detergents and wetting agents.

Oleyl alcohol is a derivative of unsaturated natural fatty acids. It is produced by catalytic hydrogenation of esters of oleic acid. Oleyl alcohol can also be derived by Boweault-Blanc reduction reaction of butyl oleate using sodium and butyl alcohol as raw materials. Furthermore, oleyl alcohol occurs naturally in fish oil and oils of other aquatic mammals. It is insoluble in water but miscible in other alcohols, ethers, and chloroform. Oleyl alcohol has broad range of industrial applications. It is used as cosmetic emollient, rheology modifier, defoaming agent, plasticizer, automotive lubricant, and chemical intermediate. Personal care, automotive, plastic, textile and leather, oil & gas, and printing ink industries are the key end-users of oleyl alcohol.
Demand for oleyl alcohol is significantly driven by the growth of personal care, textile processing, and automotive industries. Expansion in the personal care industry, which is one of the major end users, is a driving factor that is expected to positively influence the demand for oleyl alcohol by the end of 2023. Oleyl alcohol is employed as cosmetic emollient and stabilizer for preparing a wide range of topical as well as dermatological products such as eye make-up, hair shampoos and conditioners, body lotions, creams, and balms. Oleyl alcohol is manufactured using natural fatty acids derived from plant as well as animal sources; therefore, it is not reactive on human skin and thus, can be suitably used as an active cosmetic ingredient. Growth in textile processing and expansion in the automotive industry are the other driving factors that are likely to boost the market for oleyl alcohol by the end of the forecast period. Oleyl alcohol is used as a surfactant as well as softening agent during the processing of fabrics in the textile industry. It enhances the texture of the fabric, thereby improving the overall aesthetics of textiles. Oleyl alcohol is employed as a lubricating additive in grease and lube oil in the automotive industry.
Fluctuation in prices of raw materials, especially natural fatty acids, is likely to dampen the market for oleyl alcohol during the forecast period. However, increasing use of oleyl alcohol in research & development of pharmaceutical formulations for drug delivery is anticipated to provide significant growth opportunities to the global market during the next couple of years.
Asia Pacific is expected to account for the largest share of the oleyl alcohol market both in terms of production as well as consumption.
ASEAN countries such as Indonesia, Malaysia, Singapore, and Thailand currently hold the largest production base of oleochemicals, especially oleyl alcohol, and also have good trade relations with developed countries.
Furthermore, the consumption of oleyl alcohol is anticipated to be the highest in Asia Pacific due to the large population dynamics. China and India are likely to witness high demand for oleyl alcohol by the end of 2023. These countries are densely populated and have broad consumer base coupled with developing end-user markets, especially the personal care segment. Demand for oleyl alcohol in North America and Europe is anticipated to witness stabilized growth rate by 2023, due to lower population coupled with maturity in downstream markets. However, growth in these regions is likely to be supported due to usage of raw materials derived from biological resources as compared to petrochemical or synthetic derivatives. Middle East & Africa is anticipated to witness steady growth in the oleyl alcohol market due to consumption of oleyl alcohol in oil & gas, automotive, and personal care industries in the region. The region would be followed by Latin America.

What Is It?
Oleyl Alcohol and Octyldodecanol are long chain fatty alcohols. Stearyl Alcohol is a white, waxy solid with a faint odor, while Oleyl Alcohol and Octyldodecanol are clear, colorless liquids. These three ingredients are found in a wide variety of products such as hair conditioners, foundations, eye makeup, skin moisturizers, skin cleansers and other skin care products.
Why is it used in cosmetics and personal care products?
Oleyl Alcohol and Octyldodecanol help to form emulsions and prevent an emulsion from separating into its oil and liquid components. These ingredients also reduce the tendency of finished products to generate foam when shaken. When used in the formulation of skin care products, Stearyl Alcohol, Oleyl Alcohol and Octyldodecanol act as a lubricants on the skin surface, which gives the skin a soft, smooth appearance.
Stearyl Alcohol and Oleyl Alcohol are mixtures of long-chain fatty alcohols. Stearyl Alcohol consists primarily of n-octadecanol, while Oleyl Alcohol is primarily unsaturated 9-n-octadecenol. Octyldodecanol is a branched chain fatty alcohol. Fatty alcohols are higher molecular weight nonvolatile alcohols. They are produced from natural fats and oils by reduction of the fatty acid (-COOH) grouping to the hydroxyl function (-OH). Alternately, several completely synthetic routes yield fatty alcohols which may be structurally identical or similar to the naturally-derived alcohols.
Oleyl alcohol is mainly used in topical pharmaceutical formulations and is generally regarded as a nontoxic and nonirritant material at the levels employed as an excipient.
However, contact dermatitis due to oleyl alcohol has been reported. The results of acute oral toxicity and percutaneous studies in animals with products containing 8% oleyl alcohol indicate a very low toxicity. Formulations containing 8% or 20% oleyl alcohol administered by gastric intubation, at doses up to 10 g/kg bodyweight, caused no deaths and no toxic effects in rats.
Oleyl Alcohol can be used as a superfatting agent, an emulsifier, and as an emollient. It used as an oily component for cosmetic preparation such as creams and also as a solvent in cosmetic applications, such as lipstick. It is ideal for formulations where a wide pH is needed as a dispersing agent for color pigments. Oleyl alcohol can also be used as a wetting agent, defoamer, and conditioning agent.
Some applications for this diverse product includes washing lotions, hair dyes foam baths, and alcohol preparations.
