Glycerin, also known as glycerol, is a colorless, odorless, viscous liquid that is widely used in a variety of industries, including food, personal care, and pharmaceuticals. It is a humectant, meaning it attracts and retains moisture, and it is also a solvent, meaning it can dissolve other substances. Glycerin is produced naturally by the human body, and it is also found in plants and animals.
Glycerin has a long history of use, dating back to ancient times. It was first isolated from olive oil in 1783 by the Swedish chemist Carl Wilhelm Scheele. Today, glycerin is produced commercially by the hydrolysis of fats and oils.
