A liquid obtained by the decomposition of vegetable or

animal fats or fixed oils.

Glycerin occurs as a clear colorless liquid, of a thick, syrupy consistence, smooth to the touch, odorless, sweet to the taste and producing a sensation of warmth in the mouth. It is readily miscible with water or alcohol.

Properties and Uses: Glycerin is used in medicine chiefly as a solvent in preparing glycerites, and as a sweetening agent or vehicle in place of syrups.
