Dodecanol // (systematically named dodecan-1-ol) is an organic compound with the chemical formula CH3(CH2)10CH2OH (also written as C
26O). It is tasteless, colourless solid with a floral smell. It is classified as a fatty alcohol.
Production and use
Dodecanol is used to make surfactants, lubricating oils, pharmaceuticals, in the formation of monolithic polymers and as a flavor enhancing food additive. In cosmetics, dodecanol is used as an emollient.
It is also the precursor to dodecanal, an important fragrance.
In 1993, the European demand of dodecanol was around 60 thousand tons per year (Tt/a). It can be obtained from palm kernel or coconut oil fatty acids and methyl esters by hydrogenation.
Dodecanol is a mild skin irritant. It has about half the toxicity of ethanol, but it is very harmful to marine organisms.
