Sorbitan Monooleate (CAS 1338-43-8), also known as Span 80, is a non-ionic surfactant and emulsifier derived from sorbitol and oleic acid; it is a yellow, amber-toned viscous liquid used to form stable water-in-oil emulsions in foods, cosmetics, and agrochemicals, including margarines, bakery shortenings, and topical creams. It is a Technical Grade or Food Grade amber-colored viscous liquid that excels in producing stable water-in-oil (W/O) emulsions.
Commonly known as Span 80, it is widely utilized in the food industry to improve the texture and consistency of margarines and bakery shortenings. It ensures a smooth mouthfeel and prevents phase separation in various lipid-rich formulations.
In the cosmetic and pharmaceutical sectors, it serves as a skin-compatible emollient and stabilizer for topical creams. Its lipophilic nature makes it an ideal dispersing agent for pigments in makeup and oil-based therapeutic delivery systems.
