Yes, 'Oil of Wintergreen' *is* methyl salicylate. Used to be
a common way of applying an analgesic to the skin, as it
slowly hydrolyses to methanol and salicylic acid, which is
the analgesic.

I cannot imagine that the taste of methyl salicylate in that
quantity would put people off, or even if they could taste
it through the isopropanol (or better, propan-2-ol).

Methylated spirit is formulated quite differently, being
made of ethanol (drinking, and therefore taxed, alcohol). It
contains small quantities of pyridine, which smells vile,
and probably tastes worse, and is highly toxic. But if you
have resorted to drinking meths, all that is probably beyond
you.

Just back from Belgium and Luxembourg - in both countries
pure ethanol (ie 96% ethaol, 5% water, which is as pure as
you can get by distillation) was freely available on
supermarket shelves, next door to the malt whisky.

But you make acetone by oxidising propan-2-ol.
