Theres an antisceptic cream called Savlon...any link?
Anyway, about fanfic ideas, i created a creature for my story called a Zevradan. It is domestic cat size, but a cross between a dog and a zebra. It's mane is used as a binding element in advanced potions and if it slobbers on you the drool will stick and never come off, unless you rub the affected area with a foul smelling stuff rather like White Spirit.
