I've been digging on and off, and my best guess is that the hand-lotion, etc., false positives spottily reported in the press and attributed to things that sound like the "glyceri-" in nitroglycerine are, in fact, false positives rather than any attempt to target the organic base. I haven't learned nearly enough about ion mobility spectrometry (which I'm guessing to be the detection method in these cases) to speculate what actual compounds might be the culprits, or even whether they would be aminated, for that matter. If anyone wants to share, I'm all ears.
