At room temperature, cetyl alcohol takes the form of a waxy white solid or flakes.
[4] Cetyl alcohol was discovered in 1817 by the French chemist Michel Chevreul when he heated spermaceti, a waxy substance obtained from sperm whale oil, with caustic potash (potassium hydroxide).
[5] Modern production is based around the chemical reduction of ethyl palmitate.
Cetyl alcohol is used in the cosmetic industry as an opacifier in shampoos, or as an emollient, emulsifier or thickening agent in the manufacture of skin creams and lotions.
[7] It is also employed as a lubricant for nuts and bolts, and is the active ingredient in some "liquid pool covers" (forming a non-volatile surface layer to reduce water evaporation, related latent vaporization heat loss, and thus to retain heat in the pool).
