Can you eat Vaseline? The definitive answer
Many household products come with myths and misinformation about their uses, and Vaseline is no exception. This article will clarify the truth about ingesting petroleum jelly, its effects on the body, and why it is not an edible product.
What is Vaseline, and is it food-grade?
Vaseline is a brand name for petroleum jelly, a semi-solid mixture of hydrocarbons originally discovered in oil fields. The product undergoes a patented triple-purification process to remove impurities, making it safe for topical, external use on the skin. However, this does not make it suitable for consumption. There is a distinction between 'non-toxic' and 'edible.' Non-toxic means that a substance will not cause poisoning in small amounts, while edible means it can be safely consumed as food. Vaseline is non-toxic but definitely not edible. The product is formulated for application to the skin and has no nutritional value.
The effects of ingesting Vaseline
When a large amount of petroleum jelly is swallowed, the body's digestive system cannot process it because it is not digestible. This can lead to a variety of symptoms, most commonly related to gastrointestinal upset. It acts as a lubricant and laxative, speeding up the digestive process and often causing diarrhea.
Beyond digestive issues, there is a more serious risk: aspiration. This occurs when the thick, greasy substance is accidentally inhaled into the lungs, which can lead to a condition known as lipid pneumonia. Lipid pneumonia is a rare but serious lung infection that can cause coughing, chest pain, and difficulty breathing. This is particularly a risk for young children or individuals who have difficulty swallowing. For this reason, applying petroleum jelly inside the nose is strongly discouraged.
Side effects of consuming petroleum jelly
Eating a significant amount of Vaseline can cause immediate and short-term side effects. Small, incidental amounts—such as those licked off lips—are generally not a concern, but larger quantities can have a more pronounced effect on the body.
- Gastrointestinal Distress: The most common effect is abdominal pain and cramping, which is the body's reaction to trying to expel the indigestible substance.
- Diarrhea: Due to its lubricating properties, ingesting a large amount can cause a significant laxative effect, resulting in diarrhea.
- Choking Hazard: The thick, greasy consistency of petroleum jelly can pose a choking risk, particularly for children.
- Nutrient Interference: Ingesting large quantities of mineral oil, a component of petroleum jelly, can interfere with the absorption of fat-soluble vitamins like A, D, E, and K.
Comparison: Topical Use vs. Ingestion
| Feature | Topical Use (Safe) | Ingestion (Unsafe) |
|---|---|---|
| Purpose | Healing dry skin, protecting minor cuts, moisturizing lips. | None. It provides no nutritional value. |
| Effect on Body | Forms a protective, moisturizing barrier on the skin. | Acts as a laxative and can cause gastrointestinal issues. |
| Absorption | Not absorbed by the skin; remains on the surface to lock in moisture. | Not absorbed by the body; passes through the digestive system. |
| Associated Risks | Possible clogged pores for some individuals with oily skin. | Abdominal pain, diarrhea, and risk of lipid pneumonia if aspirated. |
| FDA Status | FDA recognized for protecting minor skin irritations. | Not approved or intended for internal consumption. |
What to do after accidental ingestion
If a small, incidental amount of Vaseline is swallowed (for example, while using it as a lip balm), it is generally not a cause for alarm. However, if a large amount is ingested, or if an individual shows signs of distress, it is crucial to act quickly and seek medical advice. Do not induce vomiting unless instructed to do so by a poison control center or a healthcare provider, as this can increase the risk of aspiration. Instead, contact your local poison control center for expert guidance.
Conclusion
While Vaseline is a safe and highly effective product for external skincare purposes, it is not edible. Its non-digestible nature means it can cause an upset stomach and diarrhea if consumed in large quantities. More seriously, inhaling the substance can lead to a serious lung infection. The clear takeaway is that Vaseline should only be used as directed on the label—for topical application only. The risks of ingesting it far outweigh any perceived benefit, and accidental ingestion of large amounts should be met with immediate medical consultation. Following the instructions on the packaging ensures the product remains a helpful skincare tool rather than a health hazard.
