|(what is ?)|
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
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. It may also be produced synthetically via the Ziegler process.
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.
Dodecanol can irritate the skin. It has about half the toxicity of ethanol, but it is very harmful to marine organisms.
