I've just ordered a litre of IPA, I going to decant it into small

Couldn't find any in the shops.

Typing ALK into Google suggests this is a hot topic.

Snap! I was going to say I'd done the same thing, but I ordered 5 litres
because it's useful stuff to have around (unless there's a fire!).

Does anyone know whether emollients such as Diprobase make good carriers
for the alcohol?

A cream *might* work if the alcohol doesn't disrupt the function of the
emulsifiers, but alcohol won't mix with a hydrocarbon-based ointment.

I'm not a chemist (unless A level chem 40+ years ago counts) but would be
interested to know why alcohol won't mix with a hydrocarbon-based
ointment. Alcohol is a hydrocarbon and ethanol is added to petrol. What's
different about hydrocarbon-based ointments?

Very different molecular weights.

FWIW, according to medicines.org the ingredients (excipients is apparently
the correct word) of Diprobase a Chlorocresol, Macrogol Cetostearyl
Ether, Cetostearyl alcohol, Liquid paraffin, White soft paraffin,
Phosphoric acid, Sodium dihydrogen phosphate, Sodium hydroxide, and
Purified water.
