Important Note
Propylene Glycol has been reportedly used in e-cigarette formulas. There have been no long term studies on the safety of this use. For this reason, we cannot recommend propylene glycol for that use. Until the FDA or other governing agencies gives their approval on the use of Propylene Glycol for this use customers should have the clear understanding that it may not be safe for long term use in e-vapor.
