I looked into this at one point, but basically in the U.S. if it is
not approved for that usage (the EPA approves pesticides, etc.), and
it isn't, it should not be done.  It would be interesting to see
research done on this topic, but to prove both that it kills mould
and doesn't harm paper is a multidisciplinary study that few are
equipped to undertake.
