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

Sorbitan Monooleate is used primarily as an emulsifier in preparing topical application creams, emulsions, and ointments. When used alone, Span-80 produces stable water-in-oil emulsions and microemulsions. Sorbitan Monooleate is combined with polysorbate in different proportions to prepare various water-in-oil, 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.

Packing and Storage:

In 200kg iron drum/plastic drum.

Handle with care. Span-80 should be stored in a cool, dry, and draughty place. Shelf life is two years. Then, the Span-80 surfactant can still be used if qualified after re-check.
