Question: what is in polysorbate 20?
Answer: Polysorbate-20 is fragrance component, a surfactant, an emulsifying agent, and a solubilizing agent. Polysorbate starts out as harmless sorbitol, but then it's treated with carcinogenic ethylene oxide. It's called Polysorbate 20 because it's treated with 20 "parts" of ethylene oxide.
