What is 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.
Where is Sorbitan trioleate used?
- Coatings and industrial lubricants: dispersant for pigments and fillers
- Industrial mixtures: improves suspension stability and reduces settling
- Food: under E496, stabilizes fat-based emulsions and controls crystallization in confectionery and edible oils
- Textile and leather processing: fiber lubricant and softening agent that reduces friction during wet processing
- Personal care: incorporated into anhydrous and low-water systems such as lip products and hair oils
- Its oil-soluble character supports emollient delivery and enhances the feel of cosmetic products.
Commercial specifications
- Purity specifications commonly at 97% or above depending on grade
- Packaging typically ranges from drums to intermediate bulk containers
