That would most likely be propylene glycol, which is found in many lower-quality aromatics. That could keep your tobacco moist for a long time, but many smokers choose to avoid tobacco that uses it, as it can goop up your pipes. It's probably safe to smoke, even after many years, but I don't know if time has any impact on how it tastes.
