Tween 80 (Polyoxyethylene (20) Sorbitan Monooleate) is a nonionic surfactant, readily dispersible in water, with excellent emulsifying, dispersing, solubilizing, and stabilizing properties. It is widely used in food, cosmetics, pharmaceuticals, oilfield additives, and wastewater treatment for improving texture, stability, and ingredient solubility.

Industrial emulsifiers are surface-active agents that enable the stable blending of two or more immiscible liquids—typically oil and water—by reducing the interfacial tension between them. They play a fundamental role across a broad range of industries, from coatings and paints to agrochemicals, lubricants, construction chemicals, personal care, and explosives.
