Just to refresh the memory of some folks, recall formalde
hyde is present in the 1 carbon metabolic cycle so our bodies con
tain lots of formaldehyde. I understand that formaldehyde has be
en measured in exhaled breath at 1-2 ppb. The dose does make the poison!!

Of course it is a carcinoge
n. The EU is shortening their testing list by figuring out that if a
chemical breaks down to release or is metabolized to release a carcinogen,
the chemical itself is a carcinogen. That is how their very elegant D
ye Directive effectively bans hundreds of untested dyes from use on materia
ls that will be next to the skin. The Directive has a list of 22 carc
inogens, and all you have to do is look at your dye, see where the azo bond
s are likely to break and what's left over, and you will know even without
testing whether or not you can use the stuff.
The EU, which actually
registers all chemicals proposed for use in products in commerce is up to
140,000 and counting. But only about 900 chemicals have had any sor
t of cancer testing. There isn't enough time or rats in the universe
to test 140,000 chemicals, so there has to be some short cutting. And
this is one of the ways.
If a chemical breaks down to release a car
cinogen, it's a carcinogen.

This comes up every so
often, with strong feelings on both sides, because paraformaldehyde evolves
formaldehyde gas (slowly) in solution, under some circumstances.
