Ditch said:Potions can be made of any spell of 3rd level or lower that targets one or more creatures. There are potions of invis in the DMG and the spell does in fact target one or more creatures, regardless of the "personal" range.
It must be the 'touch' version of invisibility, however, rather than the 'personal' version, because:
The imbiber of the potion is both the caster and the target. Spells with a range of personal cannot be made into potions.
