A Common Food Additive

Uses and Safety

Propylene glycol is a colorless, nearly odorless thick liquid with a variety of uses beyond being a food additive. It is commonly used as an additive to aid in the processing of foods and improve their texture, flavor, appearance, and shelf life. The Food and Drug Administration (FDA) considers propylene glycol safe for a variety of uses, including for the absorption of extra water in our foods.

Propylene glycol is also used in a solution to deliver many intravenous medications to patients, in cough medications, and in topical ointments. It is a non-toxic liquid additive that absorbs water. Propylene glycol is a compound that is GRAS (generally recognized as safe) by the US Food and Drug Administration under 21 CFR x184.1666 and is also widely used as a food additive, particularly as a humectant and solvent in various food products. Its low toxicity and ability to absorb water make it an ideal additive for a variety of food and pharmaceutical products.

Chemical, food, and pharmaceutical industries commonly use propylene glycol as an additive. According to the Agency for Toxic Substances and Disease Registry (ATSDR), it is included in over 1,200 cosmetic products and over 4,000 drug products. Propylene glycol is generally safe when used as directed, but it can cause side effects such as skin irritation, eye irritation, and respiratory problems in some people. If you experience any side effects from propylene glycol, discontinue use and consult with a healthcare professional.
