What Is Polysorbate 80 (Tween 80)?

A synthetic emulsifier derived from sorbitol and oleic acid. It is used in food to stabilize emulsions, prevent separation, and improve texture. Found in ice cream, sauces, baked goods, and supplements. Also widely used in pharmaceuticals and vaccines as a solubilizer.

Mechanism of Action

Acts as a surfactant that reduces surface tension between oil and water phases. Research published in Nature (2015) found that dietary emulsifiers including polysorbate 80 can alter gut microbiota composition, promote intestinal inflammation, and potentially contribute to metabolic syndrome in mouse models.
