Many ingredients today carry a compound that is under a lot of scrutiny lately. The compound Polysorbate 80 is a common binding agent in many products that line the shelves of grocery stores, pharmacies and other retail areas.
Polyoxyethylene-sorbitan-20-monooleate, or polysorbate 80 for short, is an amber/golden-colored viscous liquid used as as an emulsifier or surfactant in foods, medicines, skincare products, vaccines… and, of course, mouthwash. It helps bind ingredients like oil and water to each other. It is made from polyethoxylated sorbitan (chemical compounds derived from the dehydration of sugar alcohol) and oleic acid, a fatty acid found in animal and vegetable fats.
As an emulsifier in foods, it is particularly found in ice cream. Here, polysorbate is added to up to 0.5% (v/v) concentration and makes the ice cream smoother and easier to handle, as well as increasing its resistance to melting. Adding this substance prevents milk proteins from completely coating the fat droplets. This allows them to join together in chains and nets, which hold air in the mixture, and provide a firmer texture that holds its shape as the ice cream melts.
Polysorbate 80 is also used within the medical field as an excipient that is used to stabilize aqueous formulations of medications for parenteral administration, and used as an emulsifier in the manufacture of the popular anti-arrhythmic amiodarone. When added to a mixture of Tween 80 and phenol red, within laboratory tests, they cause the solution to change colour, so this is used as a test to identify the phenotype of a strain or isolate.
