What is Span 80？
Span 80 is a nonionic surfactant derived from sorbitol and oleic acid, appearing as an amber viscous liquid with a characteristic mild odor. It is insoluble in water but dispersible, and soluble in most organic solvents including ethanol and oils. As a sorbitan ester, it functions as an effective water-in-oil (W/O) emulsifier, stabilizer, and lubricant in various industrial, food, and cosmetic applications.
