Description
Oleyl alcohol (CAS 143-28-2) is a long-chain unsaturated fatty alcohol derived from oleic acid, commercially available under trade names including Novol, Oceol, Oleol, and Ocenol. It carries no E-code designation and is classified under HS code 29052990. Its molecular formula is C18H36O.
In personal care formulations, oleyl alcohol functions as an emollient and emulsifier, penetrating the lipid barrier to soften skin and stabilise oil-in-water systems. In textile and leather processing, it acts as a lubricating carrier that reduces fibre friction and improves dye penetration by modifying surface tension at the substrate level.
Oleyl alcohol is supplied as a viscous liquid in standard industrial grades compliant with REACH regulations. Cosmetic-grade material meeting Ph.Eur. or equivalent purity specifications is available for personal care applications. Typical packaging includes drums and IBC containers, with documentation available to support REACH registration requirements.
