Can you swallow propylene glycol?

Yes, it is perfectly safe to consume foods containing propylene glycol (PG). Propylene glycol can only be toxic if used intravenously at high dosage or when applied to compromised skin (burns). Once ingested, PG is either excreted in the urine or is metabolized to lactic acid, a normal metabolic product.

How much propylene glycol is toxic to humans?

A safe maximum intravenous PG dose has not been reported in the literature. However, one study reported that serum levels of PG greater than 18 mg/dL can be toxic. Other investigators have shown that toxicity is most likely to occur when the serum PG concentrations exceed 25 mg/dL.
