Answer 1

Disinfectant means it’s something that kills living bacteria cells. You’re made up of living cells too, if some cells on the skin surface die you don’t care, that’s pretty much their purpose to die protecting internals. But if it gets into cuts it kills some cells that aren’t supposed to die, so you feel the pain signaling about that
