I just did a quick search on dejanews and came up with this:

According to Michael Dresdner, in "The Woodfinishing Book":

"A good percentage of the stains based on aniline dyes, as well as the
powders themselves, are sold as nontoxic.  Yet if you look up 'aniline'
in a chemical dictionary, it is listed as quite toxic.  How is this
inconsistency possible?

"Just as there is no sin in sincere and no good in goodbye, there is no
aniline in aniline dye.  The dye is so named because aniline is used as
an intermediate in manufacturing, but none remains in the final product.

"...White flour is bleached, but no bleach remains in the bread. 
Methylene chloride is often used to decaffeinate coffee, but is
removed..."
