Sorbitan Mono Oleate
Industrial Applications
In the oil and gas industry, Sorbitan Mono Oleate is used as a primary or co-emulsifier in oil-based drilling fluids, workover fluids, and cementing systems. It stabilizes water-in-oil emulsions, reduces interfacial tension, and improves mud rheology and fluid loss control. Its thermal stability and hydrocarbon compatibility make it valuable in demanding downhole environments.
Physical Properties
Sorbitan Mono Oleate is a nonionic surfactant derived from the esterification of sorbitol with oleic acid. It typically appears as a viscous amber to dark yellow liquid with a mild fatty odor, is insoluble in water but dispersible in oils and many organic solvents, and exhibits excellent emulsifying, dispersing, and wetting properties.
