What it is

Propylene glycol is a synthetic liquid that absorbs water. It is often made from petroleum products. It is generally recognized as safe (GRAS) by the FDA for use in food.

Why it's used

Manufacturers add propylene glycol to foods to help retain moisture, act as a solvent for flavors and colors, and improve texture. It is commonly found in baked goods, candies, frostings, and some beverages.

Health notes

The FDA lists propylene glycol as GRAS. It is generally considered safe when consumed in amounts typically found in food. JECFA and EFSA have evaluated propylene glycol and established acceptable daily intakes. Some people may experience mild side effects like nausea or diarrhea if they consume very large amounts, but this is rare with typical food consumption.

Allergen info

Propylene glycol is not derived from any of the nine FDA major allergens. It does not contain gluten.
