Interesting - that looks like it could be safe, though I don’t know enough to be certain (we all know how “BPA free” turned out).
But either way it’s absolutely not the default when you buy online, which it looks like people in this post are doing, hence my comment.
I don’t see much reference to “BPA free” anymore. Why is that?
Because it was bullshit - manufacturers simply switched to BPS or other alternatives that hadn't specifically been tested yet, but were the same or worse. It turns out BPA is very hard to find a safe alternative for. And people started to realise it was bullshit. Lots of articles like this online if you google - https://www.discovermagazine.com/health/many-bpa-free-plasti...
Doing a little research, the fully phenol-free options use either vitamin C or a urea-based mixture.
