Use

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

Span-80 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. Span-80 is 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.
