Ooops! Just followed your link - seems it (IPA) is still quite toxic and is absorbed into the body where the liver oxidises it into acetone anyway... bit of a bugger that - I've never worn gloves or anything when using it, and have often used it as a hand cleanser!Careful of acetone. It can do a nasty job on the kidneys (or is it liver), and I don't mean if you drink it. It is absorbed through the skin I believe.
Best I have found is Isopropyl alcohol (or 2-propanol). This is a another of the alcohols (heavier molecule then methyl alcohol "meths", and much less toxic).
You should probably be able to get this from Boots if you ask and state why.
