Triolein (also trioleate , glycerol trioleate , Ölsäureglycerid or glycerol triesters of oleic acid ) is a chemical compound . It is a triglyceride with oleic acid and is one of the fatty oils .

Occurrence

Triolein occurs in almond oil , olive oil , lard and in many other oils of animal and vegetable origin.

Extraction and presentation

Triolein can be obtained by esterifying oleic acid with glycerine or from natural oils.

use

Triolein is used as a lubricant and emulsifier in textiles and cosmetics. The hydrogenation in hexane yields tristearin .
