What is Glycerin?
Glycerin is a simple poly compound. This solvent has a chemical formula C3H8O3. It is also known as Glycerol or glycerine.
It is hygroscopic in nature. It is found in lipids like triglycerides and is obtained from animal and plant sources. It is water-soluble due to three three hydroxyl groups.
It is colourless and viscous. It is non-toxic, odourless and has a sweet taste. It is widely used as a sweetening agent, solvent, pharmaceutical agent or emollient. It is miscible with water. Glycerin is produced through saponification, hydrolysis, transesterification of triglycerides. Synthetic glycerol can be produced by propylene.
