Span 20（Cat No.:M050983）, chemically known as sorbitan monolaurate, is a type of non-ionic surfactant derived from the esterification of sorbitol and lauric acid. It appears as a viscous, waxy solid at room temperature and is well-known for its emulsifying properties. Span 20 is widely used in the food, cosmetics, and pharmaceutical industries to stabilize emulsions, where it helps blend ingredients that typically do not mix, such as oil and water. Additionally, it is employed in the manufacture of skin care products for its moisturizing effects and ability to enhance the texture of formulations.
