Cetyl alcohol /ˈsiːtəl/, also known as hexadecan-1-ol and palmityl alcohol, is a C-16 fatty alcohol with the formula CH₃(CH₂)₁₅OH. At room temperature, cetyl alcohol takes the form of a waxy white solid or flakes. The name cetyl refers to whale oil (cetacea oil, from Latin: cetus, lit. 'whale', from Ancient Greek: κῆτος, romanized: kētos, lit. 'huge fish') from which it was first isolated.
