Does propylene glycol cause any abnormalities to inner organs?
No, propylene glycol does not have any negative effects on the human body when entering the metabolism. In the body, under conditions of normal low exposure, propylene glycol is quickly metabolised and excreted. Its metabolic pathway is comparable to that of sugar: propylene glycol is rapidly converted into lactic acid, just like what happens with the sugar (energy) in the muscles when being exercised during sports. The lactic acid is then excreted via the urine.
