General description

Glycerol is odourless, colorless, viscous in nature, and exists as a sweet tasting liquid. It can be derived naturally as well as from petrochemical feedstock. Glycerol has a wide variety of applications, and is one of the most valuable and versatile chemical substances in nature. It can be used as an emollient, solvent, sweetening agent, in pharmaceutical formulations, cosmetics, foodstuffs and toiletries. It is very stable and can be easily stored under normal temperature; also it is non-irritating and has no adverse impact to the environment.

Application

Glycerol has been used as a component of mounting medium for immunofluorescence. It has also been used as additives in poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) based inks.

Biochem/physiol Actions

Glycerol is hygroscopic in nature and is soluble in water owing to its three hydrophilic alcoholic hydroxyl groups. It can form both inter- and intramolecular hydrogen bonds, making it a very flexible molecule. The physiologic effect of glycerine is due to cell-mediated immunity, increased IgG production and increased histamine release.
