> E.g. one type of paper claims to use Ascorbic Acid (vitamin C). No idea what else is in it of course, but it's not a BGA-analogue plasticizer.

How would you know it doesn't, if you don't know what's in it?

Regardless, my point is that many BPA-analogue containing products advertise their BPA-free status.



My comment was that BPA is not used in thermal paper as a plasticizer, which that linked study was examining.


Yes, it's a used as a developer, but as is common in many cases when replacing chemicals with other chemicals -- similar chemicals have similar properties. And in fact, some BPA-free thermal paper use BPS for example.
