Glycerin (also known as glycerol) is a thick, colorless, odorless, and sweet-tasting liquid that is soluble in water. This compound is a natural sugar alcohol commonly derived from the hydrolysis of vegetable oils or animal fats. Glycerin is well-known for its hygroscopic properties (absorbing moisture from the air), its moisturizing ability, and its safety for use in a wide range of consumer products. Due to these characteristics, glycerin is widely used in products such as moisturizing lotions, laxatives, candles, mouthwash, toothpaste, soaps, body shower gels, and facial cleansers.
