Tween 80 or Polysorbate 80 (CAS: 9005-65-6) has the properties of emulsifying, wetting and foaming. It is an O/W type emulsifier with an HLB value of 15.0. It is used as an emulsifier in pesticides, food and cosmetics, and also as an emulsifier in various O/W emulsions. In the textile industry as oils and lubricants. As an emulsifier, it is often used in combination with Span-80. For Biochemical Research. Tween 80 is a Non-ionic detergent used for selective protein extraction and isolation of nuclei from mammalian cell lines. Non-ionic detergent efficiently separates hydrophilic proteins from membrane spanning, hydrophobic proteins without altering biological activity. Tween 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. Used for solubilizing membrane proteins during isolation and purification. Tween 80 is used as a surfactant in soaps, cosmetics, body washes, hair shampoos, hair loss treatments, lotions, creams, bath oils and in mouthwash in the health care industry. It serves as an emulsifier in foods such as ice cream and in the preparation of antiarrhythmic amiodarone. Further, Tween 80 acts as a solubilizing agent and excipient in the pharmaceutical industry.
