I think they tend to use something like Butane or Propane as a propellant in the spray cans. Carbon Dioxide used to be a popular propellant but nowadays everyone has been switching to something else of course.
Plus they may toss in some kerosene like stuff too. So it wouldn't surprise me if some of the substances inside the can has ether like characteristics.
The INOX spray water dispersant and lubricant appears to be quite similar to our WD-40 over here.
