Span is a nonionic surfactant, the main component of which is sorbitan fatty acid ester. It has multiple functions such as emulsification, dispersion and lubrication, and is widely used in many industries such as food, medicine, cosmetics, textiles and coatings. There are many types of Span, such as Span-20 (SP-20), Span-80 (SP-80), etc. Each type has a different HLB value and melting point depending on its fatty acid. For example, Span-80 is a yellow oily liquid with an HLB value of 4.3, and is often used as an emulsifier for oil-in-water emulsions. In addition, Span 80 is used as an emulsifier in the food industry.
