Purigen and Amquel / Novaqua / Polyaqua

According to http://www.seachem.com/en_support/support_faq.html:

"Only certain slime coat products will cause Purigen to become toxic;
the products that do this are amine based. Prime and Safe are not
amine based and so will not cause this problem. If you're curious,
what happens is that the amine compounds can strongly bind to the
resin, then when they (the amines) come into contact with any chlorine
they will form chloramines which are highly toxic. We offer a stress
coat product, StressGuard, which is not amine based and so can be used
in conjunction with Purigen."

The problem is, how do you know if a product is amine based? Of course
they don't tell you that, they just tell you to use their products
(how convenient).

Does anyone know if Kordon Amquel, Novaqua, and/or Polyaqua are "amine
based?"

I'm looking for a replacement for Carbon, and like what I have read
about Purigen, however, I use the above Kordon products.
