Sorbitan Trioleate
Sorbitan Trioleate (CAS: 26266-58-0), commercially known as Span 85, is a non-ionic lipophilic surfactant produced by esterifying sorbitan with three oleic acid chains. This amber oily liquid possesses a very low hydrophilic-lipophilic balance, making it an exceptional water-in-oil emulsifier and dispersing agent for oil-based systems. It is widely employed to stabilize emulsions in cosmetic creams and lotions, particularly in combination with polysorbates for tailored emulsion types. The pharmaceutical industry uses it in topical ointments, oral oil formulations, and injectable emulsions requiring stable dispersion of hydrophobic actives. Industrial applications include cutting oils, rust preventives, pigment dispersants, and agrochemical emulsifiable concentrates. Its excellent compatibility with mineral and vegetable oils, low toxicity, and biodegradable profile make sorbitan trioleate a dependable emulsifier across food, cosmetic, pharmaceutical, and industrial sectors.
– Water-in-Oil Emulsions: Used as the primary emulsifier in heavy creams, ointments, and oil-based formulations requiring stable dispersion of aqueous phases.
– Pharmaceutical Formulations: Serves as a co-emulsifier and dispersant in injectable lipid emulsions, oral oil systems, and topical preparations.
– Agrochemical Emulsions: Applied in emulsifiable concentrates ensuring stable dispersion of active ingredients when diluted in water for spraying.
– Industrial Lubricants and Coatings: Incorporated into cutting fluids, rust preventives, and pigment dispersions for emulsification and wetting performance.
