It is produced industrially, usually as a by-product of soap manufacture, from oils and fats. It can be made from animal fat or, in the case of vegetable glycerin, vegetable oil. 

The source of the raw material does not affect the chemistry of the final product, but, since glycerin is widely used in foods and medications, this distinction is important for vegetarians. It is also used as a sweetener and as an ingredient in a number of cosmetic products.
