:Phenol is toxic -- a large spill on your skin can be fatal. Wash it off with
:soap & water, not ethanol! In molecular biology amounts, though, phenol is
:relatively easy to handle.
I thought I'd mention: phenol is an age-old medication for
sour throat (probably just a desinfectant). I was shocked
to find that you can still buy it in Walgreens and the
likes (same as "carbolic acid"; 0.1 or 1% - don't remember
for sure). Phenol is also an ingredient in many skin
moisturizers and lip balms (0.5% in popular Carmex).
Also I don't know about "fatal" spill. It can burn the
skin for sure but being poorly soluble, it won't go very
far - not in the time it takes to wash it off.
Once popular facial phenol peels used to rejuvenate skin
basically involve soaking your skin in phenol.
I don't mean to say that phenol is harmless, of course.
