C3H8O3, commonly known as glycerol, is a colorless, odorless liquid that is sweet-tasting and viscous. It is a simple polyol compound, meaning it contains multiple hydroxyl (–OH) groups. Glycerol is widely used in food, pharmaceuticals, and cosmetics due to its moisturizing properties and ability to act as a solvent. In addition to its applications in various industries, glycerol is also a byproduct of the biodiesel production process. It can be derived from both animal and plant fats, making it a versatile and renewable resource. Glycerol is recognized for its safety and is generally regarded as non-toxic.
