Infobox references

Dodecanol, also known by its IUPAC name 1-dodecanol or dodecan-1-ol, and by its trivial name dodecyl alcohol and lauryl alcohol, is a fatty alcohol. Dodecanol is a colourless, water insoluble solid of melting point 24 °C and boiling point 259 °C. It has a floral odor. It can be obtained from palm kernel or coconut oil fatty acids and methyl esters by reduction.

Dodecanol is used to make surfactants, lubricating oils, and pharmaceuticals.

In cosmetics, dodecanol is used as an emollient.
