General description

Sorbitane trioleate, or Span 85, is a non-ionic detergent.

Application

Sorbitane trioleate, or Span 85, has been used in a study to develop a novel bottom-up process to produce nanoparticles containing protein and peptide for suspension in hydrofluoroalkane propellants. It has also been used in a study to analyze the application of liquid chromatography in polymer non-ionic antistatic additives.

Packaging
