Why is TWEEN 80 used in the media?
Tween 80 is a widely used non-ionic emulsifier that is added to cosmetics, pharmaceuticals, and foods. Addition of 0.1% Tween 80 to laboratory growth media increased the growth rate of planktonic S. aureus batch cultures, and it also increased the total biomass when S. aureus was grown as biofilms.
Can you autoclave TWEEN 80?
The product is not sterile. Autoclaving of solutions is generally not advised. Sterile filtration is more easily done if the liquid is warmed to about 40 °C and alternate portions of hot distilled water and TWEEN 80 are poured through the 0.22 µm filter. The TWEEN 80 will blend and remain in solution.
What are the side effects of polysorbate 80?
In drug formulations, polysorbate 80 has been implicated in a number of systemic reactions (e.g., hypersensitivity, nonallergic anaphylaxis, rash) and injection- and infusion-site adverse events (ISAEs; e.g., pain, erythema, thrombophlebitis) [3, 35–37].

The dilution series was made by preparing a stock solution of 128 mg/L of rifampicin or 12000 mg/L of isoeugenol in TSB or TSB with 0.1% (v/v) Tween 80. This solution was serially diluted with 2/3 step sizes in either TSB or TSB with 0.1% (v/v) Tween 80.
Can you autoclave Tween 20?
TWEEN 20 may not be stable to autoclaving, particularly with metal cations in buffer solutions. TWEEN 20 is heat sensitive and will darken when exposed to elevated temperatures.
Are emulsifiers bad for health?
A recent study suggests emulsifiers – detergent-like food additives found in a variety of processed foods – have the potential to damage the intestinal barrier, leading to inflammation and increasing our risk of chronic disease.
