But I think the vast majority of the world "knows"? Poll people on whether they're happy with various chemicals being added or ending up in their food, and the overwhelming majority would oppose it. You might simply claim they're all ignorant. Run that same poll on whether people would approve of dihydrogen monoxide [1] being added to their food, and it'd be right up their on the chopping block for banning.
But I don't think trying to trick people proves much. Obviously things like diisononyl phthalate [2] is not just a scary name for an otherwise innocuous substance. It's a scary name for a scary compound that has indeed been proven to be harmful. Nonetheless people are consuming it in large quantities, and governments are remiss to do anything. And it's just one compound among many.
Companies making billions of dollars off these products (or other products that contain them) have far more time, motivation, and ability to influence or "influence" government officials than literally anybody else. Science can help somewhat, but it's also regularly coopted as a part of the same influence game. Grants, donations, first party science, and more gray-zone areas of influence are all perfectly standard. In any case, things like diisononyl phthalate have been proven harmful in countless studies. It doesn't matter.
