I wonder if the same also happens with Propylene glycol (PG)? Seems to be widely used in cosmetics as well but has a different molecular structure.

- huytersd 3y agoPG is also the base for the liquid used in e-cigarettes
- kragen 3y agono 'glycol' just means an organic molecule with two hydroxyl groups peg is a polymer of ethylene glycol (which monomer is, incidentally, deadly, while peg is generally considered nontoxic) certainly some functional groups can be intrinsically toxic (organotin compounds come to mind) but you have hydroxyl groups on damn near every molecule in your body, including all the water molecules
- Metacelsus 3y ago> peg doesn't have two hydroxyl groups, it has thousands, because it's not a glycol, it's a polymer of ethylene glycol PEG does have exactly two hydroxyl groups: one at each end of the polymer chain. The rest are ether linkages, not hydroxyl. You're right that PEG is quite different from ethylene glycol monomer, but be careful accusing people of being ignorant when your own chemistry knowledge is not the best.
- kragen 3y agoyou are of course correct, so i have removed that assertion my own level of ignorance is life-threatening in a life form that is literally made out of molecules i appreciate your efforts to ameliorate that predicament ;)
