Cetyl alcohol (CAS No. 36653-82-4), also named 1-hexadecanol or palmityl alcohol, is a long-chain saturated primary fatty alcohol. Commercially it is mainly produced from hydrogenation of vegetable oils such as palm oil and coconut oil, instead of traditional whale wax source.Cetyl alcohol is a versatile non-ionic additive widely applied across multiple industries. In cosmetics and personal care industry, it functions as emollient, thickener, emulsion stabilizer and opacifier for creams, lotions and hair conditioners. In pharmaceutical field, it serves as ointment base and excipient for sustained-release formulations. Besides, it is used as lubricant and mold release agent for plastics & rubber, softener for textiles, lubricating oil additive for oilfield, and raw material for synthesizing fatty alcohol ethers and surfactants.
