I just looked at several safety data sheets, the first being for Apple Candy flavor from TPA and there are some very confusing things listed here that makes this sound very inappropriate for vaping. Some things listed are:
Flammable liquid and vapour.
Keep away from heat, sparks, open flames and hot surfaces. - No smoking
Use explosion-proof electrical equipment
Use only non-sparking tools.
Avoid breathing fume and vapour
Precautions for safe handling keep away from hot surfaces
Conditions to avoid: Avoid extreme heat.
Little confused how this becomes safe to vape even at low percentages
