Light Aliphatic Naphtha 59.5 - 72%
N-Heptane 17 - 27%
Propane 7 - 10%
Isobutane 3 - 5%

I assume that the Propane and Isobutane are "propellants" as they both
are in their gaseous form at normal temperatures. Propane @ -42C and
Isobutane at -11.7C.

I don't know what the combination of those gases are called. They're
a common propellant used in spray cans and possibly a waste gas
produced by petroleum distillation or cracking to produce naphtha. I
could look it up, but not now.

The active ingredient is the naphtha, which is one of the few organic
solvents that are not currently banned. There are many forms, one of
which is common Coleman camp fuel or "white-gas". As long as the
solvent doesn't leave any oil residue behind, it can be used to clean
rubber. What naphtha will not clean is dirt, which methinks is best
removed first with water.
