Water-saturated phenol is "acid phenol (phenol has a weakly ionizable
hydrogen)." What you have is likely buffered.
Start with solid phenol crystals, and saturate it with good water (you
might need to do it a couple of times). Standard safety disclaimers
apply (wear gloves and eye and body protection, etc.).
