[Introduction]
Propylene glycol is typically odorless, tasteless, and colorless, with a slightly oily or syrupy texture. It is a non-toxic liquid additive that attracts water. As a humectant, emollient, and preservative, it locks in moisture and prevents mold in certain medications, cosmetics, and foods. As a solvent, it helps improve the texture and consistency of foods, pharmaceuticals, paints, and more. It is also used to create artificial smoke.

Frequently Asked Questions
What Is Propylene Glycol?
Propylene glycol is an alcohol that absorbs water and mixes completely with many solvents. While you might see propylene glycol described as an organic compound, this does not mean it’s naturally occurring. Instead, the term "organic compound" refers to the fact that it contains carbon.
Propylene glycol in food applications
The use of propylene glycol in food is common and generally considered safe. After consumption, propylene glycol breaks down rapidly in the body (within 48 hours) and is converted into an energy source.
Unlike similar substances such as ethylene glycol, propylene glycol does not form harmful crystals when broken down in the body. Unbroken and unmetabolized propylene glycol is excreted in the urine.
Propylene glycol uses in food
Anti-caking agent: Helps prevent food from clumping
Solvent in food flavoring: Helps dissolve and mix ingredients
Dough enhancer
A method of improving flavor
Preservative: Its antimicrobial properties help kill or inhibit the growth of microorganisms such as bacteria and mold.
