Sorbitan trioleate

Sorbitan trioleate (CAS 26266-58-0), commercially known as Span 85 and approved as E496 in food applications, is a lipophilic nonionic surfactant derived from sorbitol and oleic acid. It functions primarily as an emulsifier and dispersant, stabilizing water-in-oil systems across industrial and consumer formulations. In coatings and industrial lubricants, it acts as a dispersant for pigments and fillers.

This chemical improves suspension stability and reduces settling in various industrial mixtures. Food manufacturers use it under the E496 designation to stabilize fat-based emulsions and control crystallization. It is particularly effective in confectionery and edible oils where texture control is vital. In textile and leather processing, it serves as a fiber lubricant and softening agent, reducing friction during wet processing.

Personal care formulators incorporate it into anhydrous and low-water systems such as lip products and hair oils. Its oil-soluble character supports emollient delivery and enhances the overall feel of cosmetic products. Sorbitan trioleate is supplied as an amber to yellow viscous liquid at ambient temperature. Standard commercial grades include food-grade material meeting E496 specifications and technical-grade product for industrial use.

Packaging typically ranges from drums to intermediate bulk containers for large scale operations. Purity specifications are commonly at 97% or above depending on the specific grade required for the application.
