Glycerol is the simplest triol. It can be found in all natural fats and oils as fatty esters and is an important intermediate in the metabolism of living organisms. It is completely miscible with water and many alcohols and also with many heterocyclic compounds. A remarkable and growing source of glycerol is as a byproduct in the production of biodiesel. Glycerol is presently used in a large variety of applications because of its particular combination of chemical and physical properties and because it is physiologically innocuous.
