We don't need to. We have a "Generally Recognized as Safe" standard that is well known and widely applied.

How about we just label things so consumers know whether or not the packaging contains phthalates? That way the market can decide if they want it in their package or not.

I'm not convinced labeling regulations work. Producers don't label accurately, and consumers aren't realistically in a position to make the choice being described. I live in California, where we have Prop 65 warnings on everything. The motivation there was quite similar -- people should be aware if a product or space is exposing them to substances which can cause serious harm. But I have never met a single person who refuses to enter a space with a Prop 65 warning because you basically couldn't function in society that way. When you buy a product with a Prop 65 warning, it's generally not actually feasible to know which chemical(s) (if any) prompted the warning. (Some companies may put the warning on all of their products even if only some of them actually contain such a substance.) Further, labeling for the nominal presence of some substance is not enough to make decisions -- you need to know what your actual exposure is likely to be. The system ends up being pretty useless.

In addition to what others have said, note that companies already voluntarily label their products as "phthalate free", so the market is already positioned to decide.

In the absence of concrete evidence of harm from phthalates I'm not convinced mandating yet another label would do more good than harm—it would potentially just further reduce the signal that labels provide by watering it down with yet another mandatory compliance label.

Labeling isn't bad, but it doesn't scale. It works for e.g. allergens because people who are allergic are aware of the rather rapid harm done if/when they consume allergens.

Why not?

You don't even necessarily need to put all disclaimers directly on the package. Just put some kind of reference number on there, like an MSDS number, and let users go look up all the packaging information online if necessary.

The manufacturer has this information. They must in order to produce the product. The requirement would be they just have to publish it now when used to wrap food.

How does that not "scale?"

[aidenn0]

It doesn't scale in the sense of "How can I determine which of the 27 things on the label are likely to be bad for me?"
