In light of recent revelations regarding e liquids and flavorings that contain Diacetyl, Acetoin, and/or Acetyl Propionyl, I decided to start a thread where DIYers could post results of their findings about flavors they've researched.
I'm currently waiting on responses from several suppliers that I use regularly, and as soon as I receive some information, I'll post it here. I urge other DIYers to do the same.
Also, I'm sure that Diacetyl, Acetoin, & Acetyl Propionyl aren't the only things we need to be looking out for in our juices, so if anyone has anything they'd like to share on other potentially dangerous ingredients, feel free to share that information as well.
