I have a brown-bottled product that is labeled "Formaldehyde Solution, U.S.P."
Active Ingredents:
Formaldehyde 37.0%
Methyl Alcohol 10%
Inert Ingredents 53%
Is this what y'all are referring to as "Formalin?"
(I always thought to was just plain ol' Formaldehyde.)

Yes, even if you see little milky pieces floating it is still good. Thats parrafin wax that has seperated
Yup thats the stuff, formalin is the solution made from formaldehyde. Think of formalin as diluted formaldehyde (diluted down to 37% generally)
37% is as strong as it gets, i.e. no more fromaldehyde gas can dissolve into the solution. In its' manufacture methanol is the starting ingredient and is present to attempt to prevent the chemical from breaking down. The white stuff is not parafin, it is more than likely Paraformaldehyde which is a polymerized formaldehyde after it is broken down - if you have a lot of white stuff the concentration will probably be below 37%.
you still have to dilute the formalin cause even that stuff is pretty strong eh..!just enough to make it effective and not shrink any thing
