I bet it [Bloxygen] is Air that the oxygen has been extracted from.

That's my take as well.

How well does the propane work? Say, after a year? I tried CO2 a few
times, but it didn't work. I consider it inert, but it does have a lot
of "O".
Propane works quite well so far, but I only started using it once my
free can of Bloxygen was gone. I'm using Waterlox in quart wide-mouth
canning jars and it doesn't skin at all with propane on top. I lost a
couple inches the last time I didn't use it, where the finish turned
to a gelatinous form.

I wouldn't have even considered CO2 for the reason you mentioned, the
double Os.

The O2 in CO2 is harmless - the oxygen is otherwise occupied. The
better issue is that some kinds of plastic resin use CO2 itself to cure.
Like urethanes and some kinds of silicone rubber.

Argon ought to work, as will nitrogen. Carbon dioxide may work.
Cooling (as suggested in another post) will also help, and one can do
both.

I looked up the Bloxygen MSDS. It's nitrogen (60-100%), plus some
carbon dioxide (0.0001 to 20%) and some argon (0.0001 to 20%). I bet
it's all nitrogen, plus a varying amount of contaminant gases.
