Is propylene glycol safe in food?

In many cosmetic and hygiene goods, propylene glycol is a chemical that is frequently used as a food addition or component. Food safety officials in the US and Europe have deemed it to be generally safe for use in foods. Since it is also a component of antifreeze, it has, however, raised some controversy. As a result, people began to worry about the potential hazardous effects of consuming foods containing it. Your query will be addressed in this post.

Is Propylene Glycol in Food Dangerous?

The US Food and Drug Administration (FDA) has declared that propylene glycol is "generally recognized as safe". It is both a direct and indirect food additive in the US.A maximum of 0.45 grams per pound of the finished food product may be used in Europe as a solvent for pigments, emulsifiers, antioxidants, and enzymes.A maximum daily consumption of 11.4 mg of propylene glycol per pound of body weight is advised by the World Health Organization. Overall, there haven't been any additional documented occurrences of harmful or toxic consequences of propylene glycol in food, excluding allergic individuals and one instance of excessive ingestion.However, given that current intakes are thought to be over the advised amount, it could be a good idea to cut back on dietary sources where you can, particularly given that the main sources are highly processed foods.

Health Effects of Propylene Glycol

The risks of propylene glycol are the subject of a great deal of contradictory material.While some sources claim it's harmless, others assert that it causes brain difficulties, kidney and liver failure, and heart attacks.

How Toxic Is Propylene Glycol?

Propylene glycol has extremely little toxicity. It is not known to harm genes, cause cancer, or affect fertility or reproduction. Additionally, there are no documented deaths.A meal containing propylene glycol will be eliminated by the kidneys in its unmodified form in roughly 45% of cases after consumption. The body converts the remainder into lactic acid.The accumulation of lactic acid can cause acidosis and renal failure when eaten in hazardous amounts. When the body cannot eliminate the acid quickly enough, acidosis develops.When the body cannot eliminate the acid quickly enough, acidosis develops. It starts to accumulate in the blood, interfering with normal operation.Depression of the central nervous system is the primary symptom of poisoning. Slower breathing, a slower heartbeat, and loss of consciousness are symptoms. Hemodialysis may be used to remove the poison from the blood in cases of poisoning, or the medicine or chemical containing propylene glycol may be removed.Toxicology is quite uncommon, though. Most occurrences were caused by the use of extremely high dosages of propylene glycol-containing medications or unexpected events, including one guy who became unwell and swallowed the entirety of an ice pack.

Risk of Heart Attack

Propylene glycol is said to raise the risk of heart disease and heart attacks, according to certain sources. It is true that a decrease in blood pressure and issues with heart rhythm can happen when propylene glycol is administered quickly or in large doses.Additionally, research on animals shows that very high dosages of propylene glycol can induce fast heart rate reduction, low blood pressure, and even heart stopping. However, neither cardiac issues in children nor difficulties in adults are linked to the quantity of propylene glycol contained in a typical diet.

How Can You Avoid It?

Despite the fact that propylene glycol is widely regarded as being safe, you may still decide to avoid it if you have an allergy or if you just wish to consume less of it.

By looking at the ingredient list, you may find it in many different food products. Soft beverages, marinades and dressings, cake mix, icing, popcorn, food coloring, fast food, bread, and dairy products are examples of common foods.Sadly, propylene glycol may not be shown on the food label if it serves as a carrier or solvent for another addition, such as taste or color, rather than as a primary component.The bulk of the meals that contain it, meanwhile, are highly processed junk foods. You may easily avoid the majority of sources if you eat a fresh, nutritious, whole-foods diet.

Though avoiding it could be challenging, you can also read the labels of cosmetic goods.There are several helpful websites that can help you identify which products contain it.If you have an allergy to propylene glycol, it is important to let your doctor or pharmacist know about it before taking certain medications. An alternative can usually be found.


The industrial, food, pharmaceutical, cosmetic, and other sectors utilize propylene glycol in a range of goods.Despite certain instances of toxicity caused by extremely high dosages of medicine, it is generally believed to be a relatively low-toxicity chemical.A tiny percentage of people must avoid propylene glycol-containing items due to allergies.

However, the typical concentrations seen in food products are regarded as safe for the majority of people.Remember that the majority of propylene glycol-containing foods are highly processed junk foods. Naturally, this ingredient will be present in lesser proportions in a diet rich in fresh, complete foods.
