Description
Tween 80, commonly known as polysorbate 80, is a synthetic compound that is widely applied in a variety of fields, including foods, medicines, and cosmetics. In food production, it is commonly used as a defoamer for the fermenting process of some wines and as a emulsifier in ice-cream or “puddings” to keep the creamy texture without separating. Tween 80 is also extensively applied in pharmaceutical industry, where it can be found in some vaccines, vitamins and supplements. It is an effective excipient to stabilize aqueous formulations of medications for parenteral administration and to improve the consistency of gel capsules, thus to make pills disperse in the stomach. Besides, it commonly serve as a surfactant and solubilizer in the production of soaps and cosmetics, which is effective to help dissolve ingredients and make products look creamier and more attractive. In laboratory, it is occasionally used for a test to identify the phenotype of a strain or isolate, such as mycobacteria.

Application
1. Tween 80 is used as an additive for cell culture media. It has numerous effects, e.g. increasing the transformation frequency of Brevibacterium lactofermentum or enhancing the secretion of acid and alkaline phosphatase by Neurospora crassa.
2. Tween 80 is used as an emulsifier (ice cream, whipped topping) and as a solubilizing and dispersing agent in pickles and special vitamin-mineral preparations.
3. Tween 80 is a general purpose mid-range HLB, ethoxylated, nonionic surfactant suggested for use in textile chemicals (emulsifier, lubricant), household products and cosmetic formulations (o/w emulsifier, viscosity modifier).
