Cetyl alcohol, also known as 1-hexadecanol, is a solid organic compound and a member of the alcohol class of compounds. Its chemical formula is CH3(CH2)15OH. At room temperature, cetyl alcohol takes the form of a waxy white solid or flakes.

History

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). Flakes of cetyl alcohol were left behind on cooling. A chemist is a scientist who specializes in chemistry. ... Michel Eugène Chevreul (August 31, 1786 – April 9, 1889) was an important French chemist whose work with fatty acids led to early applications in the fields of art and science. ... Spermaceti (from Latin sperma, seed, and cetus, whale), is a wax found in the head cavities and blubber of the Sperm Whale (Physeter macrocephalus), where it is dissolved in the sperm oil while the creature is living; it also occurs in other cetacea (see whale oil). ... Binomial name Physeter macrocephalus Linnaeus, 1758 Sperm Whale range (in blue) The Sperm Whale (Physeter macrocephalus) is the largest of the toothed whales and is believed to be the largest toothed animal to ever inhabit the planet. ... The chemical compound potassium hydroxide, (KOH) sometimes known as caustic potash, potassa, potash lye and potassium hydrate, is a metallic base. ...


Production

With the demise of commercial whaling, cetyl alcohol is no longer obtained from whale oil, but is instead either an end-product of the petroleum industry, or produced from vegetable oils such as palm oil and coconut oil. Production of cetyl alcohol from palm oil gives rise to one of its alternative names, palmityl alcohol.

Whale oil is the oil obtained from the blubber of various species of whales of the genus Balaena, as , Greenland or right whale (northern whale-oil), (southern whale-oil), Balaenoptera longimana, Balaenoptera borealis (Finback oil, Finner whale-oil, Humpback oil). ...

Uses

Cetyl alcohol is used in the cosmetic industry as a surfactant in shampoos and conditioners, as an emollient and as an emulsifying and thickening agent in the manufacture of skin creams and lotions. It is also employed as a lubricant for nuts and bolts. Surfactants, also known as wetting agents, lower the surface tension of a liquid, allowing easier spreading, and the interfacial tension between two liquids. ... Emollients soften skin (and moisturisers add moisture). ... An emulsion is a mixture of two immiscible substances. ...
