Polysorbate 80 is a surfactant and solubilizer used in a variety of oral and topical pharmaceutical products. Polysorbate 80 is also an excipient that is used to stabilize aqueous formulations of medications for parenteral administration, and used as an emulsifier in the making of the antiarrhythmic amiodarone .

Polysorbate 60 (polyoxyethylene (20) sorbitan monostearate) 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.
Thank you for deleting this, Polysorbate 80 has a long history of usage in parenteral drug formulation, and is on the GRAS (generally recognized as safe) list of the FDA. The concentrations used in these formulations is very small, 0.05-0.1% (w/v).

Coating these polymeric nanoparticle devices with different surfactants can also aid BBB crossing and uptake in the brain. Surfactants such as polysorbate 80, 20, 40, 60, and poloxamer 188, demonstrated positive drug delivery through the blood–brain barrier, whereas other surfactants did not yield the same results. [2]
At the same time, "E number" is sometimes misunderstood to imply approval for safe consumption. This is not necessarily the case, e.g. Avoparcin is an antibiotic once used in animal feed, but is no longer permitted in the EU, and has never been permitted for human consumption. Sodium nitrite (E250) is toxic. Sulfuric acid (E513) is caustic.
