Glycerin, also known as glycerol, is a sweet, colorless liquid that is commonly used in various products. It is a natural compound derived from fats and oils, making it safe for consumption and use on the skin. Glycerin is often found in cosmetics, food, and pharmaceuticals due to its ability to retain moisture and provide a smooth texture. In addition to its moisturizing properties, glycerin acts as a humectant, which means it helps draw water into the skin or other materials. This makes it a popular ingredient in lotions and soaps. Its versatility and safety make glycerin a valuable component in many everyday products.
