Function of Sorbitan sesquioleate：
- Span 83 molecule contains both hydrophilic sorbitol group and lipophilic oleic acid group has emulsification and lubrication function.
- Stabilising function to prevent aggregation or delamination of particles in the dispersed system.
- Antifoaming function, destroying the balance of surface tension of the foam and prompting the foam to burst.
- The hydrophilic group in the molecule of Spectra 83 gives it anti-static function and soft function.
Application of Sorbitan sesquioleate：
- In cosmetics, sorbitan sesquioleate is used to prepare creams, emulsions and ointments.
- In the food industry, Span 83 is used in fruit juice drinks and vegetable protein drinks.
- In the pharmaceutical field, Span 83 is used in the preparation of inhalants, intramuscular injections, oral liquids and so on.
- In chemical production, sorbitan sesquioleate is added as a lubricant to plastics, rubber processing
- In foodstuffs, such as (ice cream, dairy products) and coatings, ink industry, used as a stabiliser.
- In fermentation processes and oil drilling fluids, Span 83 is used as an antifoam agent to inhibit foam generation.
