Polysorbate 80 polyxoxyethylene sorbitan monooleate, (x)-sorbitan mono-9-octadecenoate poly (oxy-1,2-ethanediyl)
		Polysorbate 80 is a nonionic detergent which is often used in foods and supplements as an emulsifier.  Polysorbate 80 is produced using ethylene oxide (which is known to cause cancer in rats).  The industries that use this synthetic substance claim there is little to no research available demonstrating either its safety or toxicity, and yet it was shown to have an oestrogenic effect in rats, and it is known that following its exposure to oxygen it may produce free radicals generating peroxides and formaldehyde
