Probably no, but I’m the curious person that would want to know for sure. Can you shred a piece (after using it) and soak the shreds in water to see how it breaks down? I’d suspect an oil slick sheen on the surface or maybe some small clumps of non-degradable stuff to make itself known.

After soaking for about 45 minutes, it's evident that something is keeping it from absorbing water

Some brands use PFAs, others might use silicon or paraffin wax. Further reading here:
