Description

Span 80 (CAS NO 1338-43-8) is a high-purity sorbitan monooleate, a versatile nonionic surfactant and emulsifier. Its primary value lies in its exceptional ability to stabilize water-in-oil (W/O) emulsions and function as a solubilizer and dispersant across diverse industrial formulations. This product is essential for manufacturers in the food, cosmetics, pharmaceutical, and industrial sectors seeking reliable and consistent performance in their emulsion-based products.

Application

• As a primary emulsifier for stable water-in-oil (W/O) emulsions in cosmetics (creams, lotions) and pharmaceuticals.
• As a key ingredient in food processing for baked goods, whipped toppings, and confectionery coatings.
• As a dispersant and viscosity modifier in industrial lubricants, textile processing, and metalworking fluids.
• As a co-emulsifier and stabilizer in pesticide and agrochemical formulations.
• As a solubilizer for flavors, colors, and oil-soluble vitamins in nutraceutical and beverage applications.
• As a component in polymerization processes, particularly for PVC, as an antistatic agent and internal lubricant.
