2. Oleyl Alcohol
• 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.
3. Manufacturing Process
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
and subsequently refined.
4. Applications
• 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.
