As the resident chemistry grad student on the forums, I just wanted to share this link with you guys that talks in a little more detail about the chemical found in aquadots.
Link to:Molecule of the Day... 1,4-butanediol
In the Reuters article they link to, it says that the 1,5-pentanediol is apparently safe....which, if thats true, just goes to show how minor changes in a molecule can lead to such a large difference!
Just wanted to share this with any who are interested!
