Glycerine, also known as glycerol, is a colorless, odorless, viscous liquid that is widely used in the pharmaceutical, cosmetic, and food industries due to its non-toxic nature. It is a trihydroxy sugar alcohol that is an intermediate in carbohydrate and lipid metabolism. Glycerine is hygroscopic, meaning it has the ability to absorb water from the air, which makes it an excellent humectant, helping to maintain moisture in products. It is often obtained as a byproduct of the soap-making process (saponification) where fats and oils are heated with a strong alkali, or it can be produced synthetically. In the context of energy commodities, glycerine is relevant as a byproduct of biodiesel production. When fats or oils are chemically reacted with an alcohol (typically methanol) in the presence of a catalyst, biodiesel is formed along with glycerine.
