As far as possible and customary, SI units are used. Unless otherwise noted, the data given apply to standard conditions . |
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 ).
