Kosher all year around
Description: Propylene glycol (humectant)
Function: humectant
Rationale:
Propylene glycol is produced synthetically from petroleum-derived propylene oxide, not from grain or animal sources, and is confirmed as kosher parve without inherent Passover concern.
If you don't see a status above, it does not mean the additive is not kosher automatically - it might just not be documented in our database yet.
