What it is

Propylene glycol is a synthetic organic compound that appears as a clear, colorless, slightly thick liquid. It is produced from propylene oxide, which can be derived from petroleum or glycerol.

Why it's used

In foods, propylene glycol acts as a humectant, helping to keep products moist, and as a solvent for flavors and colors. It also functions as an emulsifier and stabilizer, commonly found in baked goods, flavorings, liquid water enhancers, and powdered drinks.

Health notes

The U.S. Food and Drug Administration (FDA) considers propylene glycol to be Generally Recognized As Safe (GRAS) for use in food. Both the Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the European Food Safety Authority (EFSA) have evaluated propylene glycol and established an acceptable daily intake. At typical intake levels found in food, it is considered safe.
