PEG, EG...

Polyethylene Glycol, Ethylene Glycol, Diethylene Glycol – when people talk about how toxic Propylene Glycol is, that's usually because they confused Propylene Glycol with one of the above mentioned, which are toxic.

This confusion is found in some articles on e-cigarettes, whether just pure ignorance or some ulterior motives are involved.


Propylene Glycol

a colorless, almost odorless, clear and viscous liquid with a faintly sweet taste, an ingredient that either alone or in combination with vegetable glycerine makes a base liquid for e-juice.

PG is used in pharmaceutical and food products for general consumption. Some people might be alergic to it (the same people who are alergic to products of everyday use that contain PG, like some toothpastes, soaps, lotions). Alergy symptoms are mild, however, if that’s your case, you should look for e-juice with Vegetable Glycerin base.
