Span-80, as a lipophilic non-ionic surfactant, is widely used in cosmetics, food, and pharmaceuticals.

Sorbitan Monooleate is used primarily as emulsifiers in the preparation of creams, emulsions, and ointments for topical application. When used alone, Span-80 produces stable water-in-oil emulsions and microemulsions.Sorbitan Monooleateis combined with polysorbate in different proportions to prepare various water-in-oil or oil-in-water emulsions or creams.

In addition, Span-80 can also be used as a solubilizer, stabilizer, softener, antistatic agent, and so on. It is also suitable for medicine, textiles, paint, and other products and industries.
