Propylene Glycol Mono & Diesters With BHT & Citric Acid

Propylene glycol mono- and diesters are made from propylene glycol, a synthetic liquid substance, and fatty acids, which can come from plant or animal sources. Citric acid is a naturally occurring acid found in citrus fruits. BHT (butylated hydroxytoluene) is a synthetic antioxidant.

This mixture acts as an emulsifier and antioxidant. It helps to blend ingredients that don't normally mix, like oil and water, and prevents fats and oils from going rancid. It is often found in baked goods like cakes, cupcakes, and snack cakes.

In the U.S., propylene glycol mono- and diesters are generally recognized as safe (GRAS) by the FDA when used for their intended purpose. BHT is also permitted as a food additive. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated these ingredients. Evidence does not suggest adverse health effects at the levels typically consumed.
