Propylene glycol classified as toxic? There's no scientific proof for that!

From Jessica99's thread:

Propylene glycol classified as toxic? There's no scientific proof for that!

Something really awful is happening now. In October 2015 German Federal Office for Chemicals, a part of Federal Institute for Occupational Safety and Health submitted a proposal to the European Chemicals Agency for a new toxicological classification of propylene glycol.

In plain words: they state that this compound is toxic for a specific organ (in this case – the respiratory tract) in our body even after a single contact.

What? Internet forums are quoted as a scientific source? Now this is just ridiculous.

It is just an absurd to include in an official report a forum entry from an anonymous internet man/woman having absolutely no knowledge of the subject – as can be clearly seen from the toxicity data presented above.

Fortunately, submission of the proposal is just the beginning. Right now it is time for consultation. The deadline is April, 21st. I do really hope that we, vapers, have to act. This applies to toxicologists, doctors, chemists, but also to organizations. Everyone should do something.

It seems that this would be the best way to attack one of the most important ingredients in vaping, just turn it into something dangerous. Never mind the fact that the need to classify it as toxic for inhalation didn't arise until now.

After 4 years vaping 80% or higher
PG in my diy I've never felt better.
Well to qualify that statement,
it's not like I'm still 50.ha
Or toxic. haha. ymmv. cheers.

Politics has pretty much taken over science in the USA as well.
so no more PG in prescription inhalers?
Fog machines banned in Germany?

"2.2 Short summary of the scientific justification for the CLH proposal


Among many other uses propane-1,2-diol is commonly used to produce artificial smoke with generators in theatres, discotheques, emergency trainings or is used as a liquid for vaporisation in electronic cigarettes.

A number of internet forums indicate that the inhalation of propane-1,2-diol aerosol/vapour may have adverse effect to the respiratory tract if inhaled, e.g.:"

Man... You can Make this Stuff Up.

Oh Wait... This is an Internet Forum. So I can Make things Up. And be considered an (Internet) Expert while I Do.

Unfortunately, I'm Not Making this Up. And they actually did reference Internet Forums in the "Scientific Justifications" section.
