Description
1-Octadecanol (CAS 112-92-5) is a long-chain fatty alcohol derived from natural stearic acid, commercially available under trade names including Stearol, Adol 68, Sipol S, Aldol 62, and Lorol 28. It carries no assigned E-code and is registered under EC 204-017-6. Its C18 saturated structure gives it a defined melting point and low reactivity profile.
In personal care formulations, 1-octadecanol functions as an emulsion stabilizer by reinforcing the interfacial film between oil and water phases, reducing droplet coalescence over time. In metalworking lubricants, its hydroxyl group adsorbs onto metal surfaces, forming a boundary film that reduces friction and tool wear under moderate load conditions.
The material is supplied as white flakes conforming to Ph.Eur. and FCC grade specifications where applicable, and is fully registered under REACH. Standard packaging includes 25 kg bags and bulk options. Procurement teams should confirm grade specification against intended application prior to ordering.
