Tween 80, also known as Polysorbate 80, is a non-ionic surfactant widely utilized in various industries due to its excellent emulsifying and solubilizing properties. This compound is particularly valued in the pharmaceutical and food sectors, where it serves as an effective emulsifier in formulations, enhancing the stability and texture of products. Its ability to improve the bioavailability of active ingredients makes it a preferred choice in drug delivery systems, particularly in the formulation of vaccines and oral medications. Additionally, Tween 80 is commonly used in cosmetic products, where it helps to create smooth and stable emulsions, ensuring a pleasant application experience.

The unique structure of Tween 80 allows it to reduce surface tension, making it an effective agent for stabilizing oil-in-water emulsions. This characteristic is especially beneficial in the food industry, where it aids in the uniform distribution of flavors and nutrients in products such as sauces and dressings. Researchers also leverage Tween 80 in laboratory settings for cell culture applications and as a dispersing agent in various formulations. Its versatility and effectiveness in enhancing product performance make Tween 80 an essential ingredient across multiple sectors.
