I went ahead and looked it up, botox is in the manual here at work. 8 distinct strains of Clostridium botulinum, only two generally associated with infections in humans. Spore former, yes. C. botulinum spores can survive 100°C (rendundant I know) for 5+ hours, but C. botulinum spores will be rendered non-viable after five minutes at 120°C. 120°C ~ 248°F.
C. botulinum toxin or 'botox' is just a polypeptide, a mid sized protein. The toxin is denatured by heat at 80°C (~176°F) more or less instantly, the polypetide toxin will also be instantly rendered harmless on contact with a solution of 10% bleach in water.
Would I use a bottle brought known to be contaminated with Botox? Yes I would. Would I try to disinfect a bottle that was not mechanically clean glass first, no I wouldn't. I dunno if Star-San works on Anthrax or whatever else, but I know bleach does.
