Crayon Composition: What's Inside a Crayon?
Standard crayons are not made with ingredients meant for human consumption. The primary components are wax and color pigment. The most common wax used is paraffin wax, a byproduct of petroleum processing. While classified as food-grade for some applications like coating candies or cheeses, the amount and form in crayons are not designed for digestion. The colorful pigments mixed into the wax can be organic or inorganic and are also not intended as food. Some specialty or natural crayons might use beeswax or soy wax, but these are still not formulated to be consumed.
The 'Non-Toxic' Label Explained
Many crayon boxes, especially those for children, prominently feature a 'non-toxic' label. This certification, often from the Art and Creative Materials Institute (ACMI), means the product does not contain any material in sufficient quantities to be harmful to humans, including children, even if ingested in small amounts. The 'non-toxic' label is crucial for children's art supplies, given the tendency of toddlers to put things in their mouths as part of their exploration. However, this designation does not mean the item is edible or provides any nutritional benefit. It simply indicates that accidental, small-scale ingestion is unlikely to cause serious poisoning.
The Journey of an Ingested Crayon
When a crayon is eaten, it does not get processed like food. The wax has a relatively high melting point and is not readily digestible by the human gastrointestinal tract. This means it will pass through the body relatively intact. The most likely outcome is a colorful bowel movement, which can be an alarming but harmless sight for parents. The pigments, being indigestible, will also pass through the digestive system without providing any vitamins, minerals, or other nutrients.
Potential Health Risks
While generally safe in small quantities, ingesting crayons is not without risk. The dangers escalate depending on the amount consumed and the individual's age and health.
- Choking Hazard: For infants and toddlers, any small object, including a piece of a crayon, is a potential choking hazard. This is the most immediate and serious risk associated with crayon ingestion.
- Stomach Upset: The paraffin wax can have a mild laxative effect, which can lead to a stomach ache, loose stools, or diarrhea. This is typically a temporary and minor issue.
- Intestinal Obstruction: In cases where a child ingests an excessive number of crayons, the wax can clump together and potentially cause a bowel obstruction. This is a rare but serious complication that may require medical intervention.
- Pica: The compulsive eating of non-food items, including crayons, is a condition known as pica. If a child consistently eats crayons, it may be a sign of a developmental or nutrient deficiency that requires a doctor's attention.
Comparison: Standard Crayons vs. Edible Alternatives
| Feature | Standard Crayons (e.g., Crayola) | Edible Crayons (e.g., MilTreats) |
|---|---|---|
| Primary Ingredients | Paraffin wax, color pigments | White Belgian chocolate, food-grade coloring |
| Intended Use | Art supply for coloring and drawing | Art supply and snack food |
| Nutritional Value | None; contains indigestible wax and pigments | Provides calories, sugar, and fat from chocolate |
| Health Risks | Choking, stomach upset, potential obstruction | Minimal health risks if consumed as intended |
| Safety Label | Certified as 'non-toxic' for accidental ingestion | Labeled as 'edible' and safe for consumption |
Edible Crayons: A Safe Option
For parents particularly concerned about their children ingesting art supplies, some companies have developed specialty edible crayons. These are made from food-grade ingredients, such as chocolate and natural dyes, ensuring that they are safe to eat. They provide a fun, dual-purpose option for creating art and enjoying a treat without the worry of ingesting non-nutritive substances.
Crayon Alternatives for Infants and Toddlers
If you have a young child in the exploratory stage, there are several safer, and more natural, options to consider.
- Beeswax Crayons: Made with natural beeswax and food-grade pigments, these crayons are a step up in safety from standard paraffin wax versions.
- Soy Crayons: Similar to beeswax crayons, soy crayons use soy wax and natural colorants, making them a biodegradable and non-toxic choice.
- Food-Based Coloring: For the youngest artists, using food items like fruit puree, vegetable purees, or food coloring with water on paper can be a completely safe, if messier, option.
- Large, Thick Crayons: The Art and Creative Materials Institute (ACMI) often certifies products with a large, chunky design that reduces the choking hazard for small children.
Conclusion
In summary, the question "do crayons have nutritional value?" has a clear and unambiguous answer: no. They contain no vitamins, minerals, protein, or any other component beneficial to human health. Instead, they are composed of non-digestible wax and color pigments. While the 'non-toxic' label on most modern crayons means that a small accidental bite is not a cause for panic, it is important to remember that they are art supplies, not food. The primary risks associated with ingestion are choking, stomach upset, and in rare cases, intestinal blockage. For peace of mind, especially with toddlers, parents can choose certified non-toxic art supplies or explore edible alternatives designed specifically for this purpose. Always supervise young children during craft time to prevent any accidental ingestion and address concerns about pica with a healthcare provider if necessary.
Final Safety Tip

The takeaway: A colorful craft supply, not a colorful snack.
Crayons are essential for creativity, but they have no place in a healthy diet. Their lack of nutritional value and potential for physical harm from ingestion means they should always be treated as a tool for art, not a snack.

Why are crayons non-toxic but not safe to eat?
It's a matter of intended use and toxicity thresholds. Non-toxic means the components are not poisonous in small amounts, but non-edible means they are not food and offer no nutritional benefit. They can still cause physical issues if ingested.
Can a person get sick from eating a crayon?
Yes, a person can get an upset stomach or diarrhea from eating a crayon due to the laxative effect of the wax. Serious illness is rare from small amounts but possible with large quantities.
Are there any healthy alternatives to crayons?
Yes, some alternatives include crayons made from natural beeswax or soy wax, and food-based coloring activities for infants and toddlers.
Do all crayon brands use the same ingredients?
No, while paraffin wax is common, different brands use varying formulations. Specialty brands may use beeswax or soy, and food-grade edible crayons use entirely different ingredients like chocolate.
Is pica the only reason a child might eat crayons?
No, young children often put objects in their mouths as a way to explore their environment. However, if the behavior persists, it could be a sign of pica.
Can pets get sick from eating crayons?
Yes, similar to humans, pets can get an upset stomach or intestinal blockage from eating crayons. It is recommended to contact a vet if your pet ingests a crayon.
