With respect, I think you are talking nonsense and potentially creating a totally unnecessary scare.
"Polysorbate 80, also known as polyoxyethylene sorbitan monooleate or Tween™ 80, is an amber-colored, viscous liquid with a slightly bitter taste. It is used primarily as an emulsifier in food products, cosmetics, vitamins, medicines, and vaccines. The product is a derivative of sorbitol and oleic acid, and is manufactured worldwide.
Emulsifiers help bind ingredients together and keep them from separating, most commonly with oil and water. It is also a surfactant – a substance which reduces the surface tension of a liquid – which results in an easier, smoother spread. Frequently, it is used in ice cream and frozen desserts to resist melting. Polysorbate 80 is also used as an emulsifier and surfactant in products such as shortening, condiments, chewing gum, dietary foods, and whipped dessert toppings, as well as a host of cosmetic creams and lotions."
"Polysorbate 80 (commercially also known as Tween 80, a registered trademark of ICI Americas, Inc.).....Polysorbate 80 is also used in some eye drops (i.e. ROHTO cool redness reliever/lubricant eye drops)....Polysorbate 80 is used as an emulsifier in the manufacture of medications for parenteral administration, most notably in the popular anti-arrhythmic amiodarone. [6] It is also part of the adjuvant used in some European and Canadian influenza vaccines.[7] It is also used in the culture of Mycobacterium tuberculosis in Middlebrook 7H9 broth.....In Europe and America people eat about 0.1 g of polysorbate 80 in foods per day.[8] Influenza vaccines contain 0.000025 g of polysorbate 80 per dose.[7]
In general, polysorbate 80 is safe and well-tolerated, although a small number of people are allergic to this substance.[9] Rats fed with diets containing up to 5% polysorbate 80 by volume showed no toxic effects.[10] Polysorbate 80 is not carcinogenic.[11] A 1956 study saw no effect on reproduction in rats at up to 5% of their diet being polysorbate 80, although reproduction decreased at 20% of the diet.[12] A 1993 study raised concerns that polysorbate 80 might decrease fertility in rats.[13] A 1997 study looked at the effect of consuming three doses by body weight of 0.5%/day on the sex organs of female rats and saw no abnormal changes; this is equivalent to a 70 kg person consuming about 350 g per day for three days.[14] A 2008 study concluded that there was no observable adverse effects at doses per body weight of up to 1.85 ml/kg·day, which is equivalent to a 70 kg person consuming about 140 g of this substance per day for 21 days. However, administration of 16.783 ml/kg·day to pregnant rats lowered body weight in male and female offspring.[8] This is equivalent to a person consuming about 1.3 kg of polysorbate 80 per day for 21 days."
