Description and Uses
Span 80, also known as sorbitan monooleate, is a nonionic surfactant and emulsifier. It belongs to the family of sorbitan esters. This ingredient is produced by esterifying sorbitan with oleic acid, a fatty acid in many vegetable oils. Span 80 emulsifier presents as a light yellow, viscous, oily liquid. Its solubility characteristics include insolubility in water and solubility in organic solvents. Span 80 is an emulsifier, stabilizer, and dispersant used in the food, pharmaceutical, and cosmetics industries.
Span 80 is a low HLB surfactant suggested for use as a w/o emulsifier or as an o/w emulsifier for use in cosmetic formulations, oil field chemicals, plastics, household products, coatings and textiles.
