What is polysorbate-80? “Polysorbate 80 is a surfactant commonly used in the pharmaceutical, cosmetic and food industry. Surfactants are compounds that reduce the surface tension and increase the solubility between two liquids that would normally be unable to dissolve together, e.g. oil in water.” (thevaccinereaction)

“Polysorbate-80 and carboxymethylcellulose are two such additives that have recently been linked to alterations in gut bacteria and even colon cancer.” (stopcoloncancernow)

“Polysorbate 80 has been associated with a number of adverse events. In food, small concentrations of undigested polysorbate 80 may enhance bacterial translocation across intestinal epithelia, a potential explanation for an observed increase in the incidence of Crohn’s disease [34]. 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) [33537]. Polysorbate 80 has also been implicated in cases of renal and liver toxicity [3840].” (safetyofpolysorbate-80)

“It is used to allow ingredients that normally would not be able to cross the blood brain barrier, to pass into the brain. “Polysorbate 80 is used as an emulsifier by the pharmaceutical industry to enhance the delivery of chemicals/drugs from the blood into the brain across the blood brain barrier (BBB). Being that the BBB is impermeable to many things in the bloodstream, researchers needed to find a way to deliver chemicals/drugs into the brain from the bloodstream in order to treat hard-to-reach brain infections/lesions/tumors, etc. Polysorbate 80 is one such chemical that helps in this delivery.” (truthsnitch)


Tween 80 (polysorbate 80, polyoxyethylene sorbitan monooleate). “Neonatal female rats were injected ip (0.1 ml/rat) with Tween 80 in 1, 5 or 10% aqueous solution on days 4-7 after birth. Treatment with Tween 80 accelerated maturation, prolonged the oestrus cycle, and induced persistent vaginal oestrus. The relative weight of the uterus and ovaries was decreased relative to the untreated controls. Squamous cell metaplasia of the epithelial lining of the uterus and cytological changes in the uterus were indicative of chronic oestrogenic stimulation. Ovaries were without corpora lutea, and had degenerative follicles.” (pubmed Delayed effects of neonatal exposure to Tween 80 on female reproductive organs in rats)

“In mice, relatively low concentrations of two commonly used emulsifiers, namely carboxymethylcellulose and polysorbate-80, induced low-grade inflammation and obesity/metabolic syndrome in wild-type hosts and promoted robust colitis in mice predisposed to this disorder…Moreover, they suggest that the broad use of emulsifying agents might be contributing to an increased societal incidence of obesity/metabolic syndrome and other chronic inflammatory diseases.” (pubmed)

“May cause adverse reproductive effects based on animal test data. No human data found. May cause cancer based on animal test data. No human data found. May affect genetic material (mutagenic).” Under the special remarks on other toxic effects on humans is stated, “Animal studies have shown it to cause cardiac changes, changes in behavior (altered sleep time) and weight loss (upon repeated or prolonged ingestion.) However, no similar human data has been reported.” (truthsnitch)

Polysorbate 80 is used in pharmacology to assist in the delivery of certain drugs or chemotherapeutic agents across the blood-brain-barrier. This raises serious concerns of using Polysorbate 80 in combination with other reactive vaccine ingredients, which have the potential to damage the brain….The fact that Polysorbate 80 “may cause cancer based on animal test data” and may be mutagenic alone should be enough to require vaccine manufacturers and the Food and Drug Administration to provide credible scientific evidence that it is safe to include  Polysorbate 80 in vaccines given to humans.” (thevaccinereaction)

If the blood brain barrier is set up to protect our brains, is it possible that the injection of polysorbate-80 could allow the ingredients in the vaccines including aluminum to enter our brains? Is it possible that polysorbate-80 both in our food and in vaccines could be leading to more gut permeability and Crohn’s? Is it possible if not probable that polysorbate-80 in vaccines isn’t safe?

Now you can decide for yourself if you think it is safe to inject polysorbate-80.
