Glcerine (aka glycerol, glycerin) is approved for inhalation in medical applications such as inhalers. The entire contents of the first post have been deleted.
Dow Chemical make all grades of PG and VG, and advise that their pharmaceutical grade glycerine 'Optim' is the most suitable product of all for medical inhalation duty.
Food grade glycerine is NOT suitable for inhalation - only pharmaceutical grade is. Only 'Glycerine, USP' or 'Glycerine, BP' or 'Glycerine, EU' are pharma grade - a glycerine product with ANY OTHER labelling OF ANY KIND is NOT suitable. Glycerine products without the USP/BP label are most likely food grade but could be agricultural grade or industrial grade. Only inhale pharmaceutical grade materials.
Acrolein has not been detected in e-cigarette vapor even at 300 C (a heat decomposition product of glycerine).
