We have the ingredients for our Shuffleboard Table wax-based product, suitable for home or commercial applications. The main base material used on both types of shuffleboard wax or powder is Polystyrene (PS) beads. The kind we use does not contain Pentane, which is used in Expanded Polystyrene (EPS) to create the foam structure, making it lightweight and insulating, but not fireproof. They use this material to make styrofoam. The beads, which aren't acutely toxic in solid form but pose risks from potential styrene leaching (a possible carcinogen), especially when heated, and present physical hazards like choking or intestinal blockage if ingested. Research also shows that ingestion of microplastic PS beads can promote inflammation and metabolic issues in animals, suggesting long-term concerns. Handling them is generally safe, but inhaling dust or vapors (from heating) or getting them in the eyes needs caution. 

Brown Shuffleboard powder or wax ingredients 

Ground walnut shells have been a principal component of our brown wax. We feel the potential allergic risk is low, but as a precaution, we only send out the yellow wax with our shuffleboard tables. See warnings below about potential risk of walnut shells used in our Shuffleboard Table Wax of Powder 

Allergy Awareness: 

Crushed Walnut Shells in Shuffleboard Wax Walnuts (Juglandaceae) belong to the tree nut family, a common allergen group that can trigger reactions ranging from mild oral itching to severe anaphylaxis. In the United States, walnuts account for an estimated 20–30% of all tree nut allergies, which typically affect between 0.05% and 2.0% of the population.

Kernel vs. Shell: Understanding the Risk

The primary risk associated with walnut allergies stems from the ingestion of the walnut kernel (the fruit). Scientists have identified five specific proteins (Jug r 1–5) in the kernel responsible for these reactions. Importantly, 

These proteins are not naturally present in the walnut shell. Because shuffleboard wax is not intended for ingestion, the risk of a systemic allergic reaction through normal use is considered extremely low.

Dermal Exposure and Skin Safety

Crushed walnut shells are widely used as abrasives in cosmetics and exfoliants, where they are often in contact with the skin without incident. There is no evidence suggesting that walnut shells cause skin sensitization or acute toxicity. While some Safety Data Sheets (SDS) for walnut-based products include allergy warnings, these are precautionary measures due to the theoretical possibility of trace kernel dust remaining on the shells during industrial processing.

Addressing Potential Irritants

Some individuals report skin irritation (contact dermatitis) or staining when handling "green" walnut husks or hulls during harvest. This is caused by Juglone, a natural compound found in the fleshy outer hull. However, 

Juglone is not present in the dried, processed walnut shells used in shuffleboard wax, and there are no reports of dermatitis linked to the shells themselves.

Summary for Sensitive Individuals

While walnut shells lack the allergenic proteins found in the nut meat, individuals with severe walnut allergies should be aware that trace cross-contamination can occur during the milling process. However, for the vast majority of users, skin contact with walnut-shell-based shuffleboard wax does not pose a known health hazard.

Our yellow shuffleboard wax uses food-grade corn meal, which poses potential health risks, primarily from inhalation and skin irritation, especially with prolonged or excessive exposure. While corn-derived ingredients are generally considered safe for use in shuffleboard table wax or powder when properly formulated, using bulk corn meal powder in an unregulated manner raises concerns. 

Key Health Risks

• Inhalation Hazards: Inhaling any fine powder, including cornmeal or cornstarch, can cause respiratory irritation, coughing, and chest pain. In extreme cases (e.g., in infants or high-pressure occupational exposure), significant inhalation can lead to serious respiratory distress or pneumonitis (lung inflammation). The body treats inhaled powder as a foreign body, which can trigger inflammatory responses in the airways and lungs.
• Skin Irritation and Fungal Growth: While corn meal is used in some cosmetic applications, prolonged skin contact may cause temporary irritation in some individuals. A significant concern is that cornstarch can attract moisture and potentially promote the growth of Candida albicans (a type of yeast) in moist skin folds or on active rashes.
• Allergic Reactions: Individuals with corn allergies or sensitivities may experience allergic reactions, including skin rashes or respiratory symptoms, upon contact or inhalation.
• Bacterial Contamination: As a food product, cornmeal is a carbohydrate source that can attract microbes if stored improperly or used past its expiration date.
• Dust Explosion Risk: While not a health risk, corn meal dust dispersed in the air can form an explosive mixture if exposed to an ignition source.

Conclusion

Food-grade corn meal should not be assumed to be entirely harmless when used outside its intended purpose as an ingredient for consumption. The primary risks stem from using it as a fine, loose powder, especially when it leads to inhalation or prolonged, moist skin contact. It is safest to use products specifically designed for powder applications, such as our yellow shuffleboard table wax.
