1-Tetradecanol (or myristyl alcohol ) is a long-chain, monohydric alcohol from the group of fatty alcohols . It is a white, waxy solid with a fatty acid odor.

Occurrence

1-Tetradecanol occurs in bound form in whale rat .

Extraction and presentation

1-tetradecanol, by reduction of myristic or some Fettsäureestern with reagents such as lithium aluminum hydride or sodium are obtained.

It can also be made from coconut oil or through biotechnological processes.

use

1-Tetradecanol is used as an additive in cosmetics (for wetting agents, as a defoamer and fixative) and as a raw material for the production of fatty alcohol sulfates, salts and esters (e.g. myristyl lactate, myristyl myristate, myristin ).
