polyoxyethylensorbitanmonooleat

Polyoxyethylensorbitanmonooleat, commonly known as polysorbate 80 or Tween 80, is a non-ionic surfactant and emulsifier. It is derived from sorbitol, which is treated with ethylene oxide and then reacted with oleic acid. This process results in a viscous, yellowish liquid that is soluble in water and ethanol. Its primary function is to help mix oil and water, preventing them from separating in various products.

In the food industry, polyoxyethylensorbitanmonooleat is used as an emulsifier in ice cream, baked goods, and dressings, contributing to a smoother texture and extended shelf life. It can also be found in some pharmaceuticals and cosmetics, where it acts as a solubilizer for active ingredients and helps to create stable emulsions in lotions and creams. In laboratory settings, it is employed as a component of cell culture media and in the purification of proteins. Due to its ability to reduce surface tension, it finds applications in agricultural formulations as well. The safety of polysorbate 80 has been evaluated by regulatory bodies, and it is generally considered safe for use within specified limits.
