Polysorbate 80 (polyoxyethylene (20) sorbitan monooleate) The number following the 'polysorbate' part is related to the type of major fatty acid associated with the molecule. Monolaurate is indicated by 20, monopalmitate is indicated by 40, monostearate by 60, and monooleate by 80.
The chemical structure shown for Polysorbate 80 appears to be incorrect. Polysorbate 80 is made by polymerization of 20 equivalents of ethylene oxide with sorbitan monooleate [1]. The method of synthesis is summarized in Chapter 2 of Food Emulsifiers and Their Applications: Hasenhuettl, Gerard L., Hartel, Richard W. (Eds.) [2]. Aside from the ...
In molecular biology, TBST (or TTBS) is a mixture of tris-buffered saline (TBS) (a buffer solution) and Polysorbate 20 (a polysorbate-type nonionic surfactant).Polysorbate 20 is also known as Tween 20, a commercial brand name.
Polysorbate 20 is used by philatelists to remove stamps from envelopes and to remove residues from stamps, without harming the stamp itself. Polysorbate 20 is also used as wetting agent in rubber balers in the elastomer industry. Polysorbate 20 has been used as a shape directing agent to synthesize spheroidal magnetite nanoassemblies. [5]
