Oh this is a very good point. Type and amount of additives is very rarely specified, although you can find some info in the academic literature.

  As a person completely naive to the finer points of plastics manufacture-do these additives tend to be drawn from a fairly small and well-understood universe of chemicals and combined in predictable ways, or is it a bit more DIY at the level of a specific manufacturing plant or product spec or batch run? I guess my mind is instinctively reaching for the ways FDA attempts to ensure food safety by compelling manufacturers to publish ingredient lists, and by maintaining registries [0] of hopefully-well-understood additives (and banning the rest, in historically dangerous categories like colorants). Sure from time to time agitators take that information out of context to whip up a scare about one ingredient or another, and sure some of the food that comes in from overseas has after-the-fact labeling that’s a little sus. But at least there’s an expectation that the information must exist and be legible.
