Polysorbate 80, also known as Tween 80, is a nonionic surfactant and emulsifier commonly used in the food, pharmaceutical, and cosmetic industries.
Its IUPAC name is polyoxyethylene (20) sorbitan monooleate, and it is derived from sorbitol, an alcohol sugar, and oleic acid, a long-chain fatty acid.
As an emulsifier, Polysorbate 80 plays a critical role in stabilizing mixtures of oil and water by reducing surface tension.
It is also used to solubilize hydrophobic compounds, making them easier to incorporate into aqueous formulations.
This surfactant is often identified by its E number, E433, when used in food products within the European Union.
It has wide applications in enhancing the texture, appearance, and stability of various products, from food items like ice cream to pharmaceutical formulations such as injectable drugs and vaccines.
The significance of Polysorbate 80 spans a variety of industries, given its versatile nature and effectiveness in different formulations.
