Interesting that at that link it says that LPG is the propellant, yet
the MSDS that they provide a link for shows CO2 as an
ingredient. There is no mention of LPG. As a more definitive answer
on the current formulation, the FAQ at wd40.com says:
What is the propellant in WD-40?
A propellant is the stuff that helps pump WD-40 out of the can. The
propellant used in WD-40 is carbon dioxide (CO2). CO2 is an inert gas
which helps empty the can. Plus, the addition of CO2 reduced the
number of VOCs, which helps preserve the environment. Be sure to
point the spray nozzle toward the dot on the top of the can to ensure
that the can fully empties.
