Formaline formation
http://bridgeslab.sph.umich.edu/protocols/index.php/SOP_-_Formalin_and_Paraformaldehyde WebFormalin is a 40% solution of formaldehyde in water. It has been used for many years in concentrations of 2–4% to treat radiation-induced hemorrhagic proctitis. Only a few minor complications have been reported after treatment – acute proctitis, worsening of radiation-induced strictures, worsening of incontinence, and severe pain ( 6c, 7c ).
