Peanut Oil · Cast Iron Cookware Seasoning
Crisbee Puck Cast Iron Seasoning
Lower concern. Oil-based cast iron seasoning, no PFAS-prone coatings.
Crisbee is a peanut oil and beeswax seasoning for cast iron. Oil-based products inherently avoid PFAS; no nonstick or water-repellent chemistry involved.

The full breakdown
What it's made of and why it matters
Crisbee Puck is a solid blend of peanut oil and beeswax designed to season and protect cast iron cookware. Peanut oil is a triglyceride fat that polymerizes when heated, building non-stick patina on cast iron; beeswax acts as a hard finish barrier. Neither ingredient is synthetic or prone to breaking down into harmful compounds under normal stovetop use. The product contains no ceramic, enamel, or synthetic polymer coatings that could flake, leach metals, or release fumes.
The brand's record and disclosure
Crisbee (peanut oil brand) maintains minimal public disclosure on third-party testing or certifications. No major product recalls or safety controversies are on record for this seasoning line. The brand does not make explicit claims about heavy metals, pesticide residues in the peanut oil, or allergen controls, though peanut oil itself is a common food product subject to standard agricultural oversight. No PFAS-related statements have been identified.
How it compares in its category
Cast iron seasoning products range from pure oils (coconut, avocado, mineral) to proprietary blends. Crisbee's peanut-beeswax formulation sits in the middle-ground: more durable and heat-stable than raw oils alone, but simpler and less chemically processed than some synthetic seasoning pastes or enamel restorers. It avoids the lead/cadmium risks of vintage enameled cookware and the Teflon-type coating fume concerns of non-stick coatings, making it safer than many commercial cast iron maintenance options.
If you buy it
Apply thin layers to warm (not smoking) cast iron, then buff away excess to prevent rancid buildup. Avoid heating the seasoning above typical stovetop temperatures (below 450F for beeswax stability). Replace or reapply every 6-12 months depending on use; discard if the puck develops off-odors or mold. Store in a cool, dry place to prevent the oil from becoming rancid, which can create unpleasant flavors if it contacts food.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Peanut allergen contamination
Peanut oil is a known allergen source. Cross-contamination risk depends on manufacturing controls; Crisbee does not publicly detail allergen protocols. For highly sensitive individuals, skin contact during application or airborne exposure during heating could pose concern, though ingestion risk from seasoning is low.
Oil rancidity and off-flavors
Peanut oil can oxidize and become rancid if stored improperly or left on cast iron too long without use. Rancid oil imparts unpleasant tastes to cooked food and may produce low levels of oxidation byproducts; this is a practical rather than acute toxicity issue.
Pesticide residues in peanut oil
Peanuts are a conventionally farmed crop and may retain pesticide residues, but no specific contamination has been reported in Crisbee products. Refined peanut oil undergoes processing that typically removes most residual pesticides. No independent testing data is publicly available for this brand.
Lead or cadmium in the cast iron itself
This product does not introduce new metals to cookware; it seals existing cast iron. Risk depends on the pan's age and source. Vintage cast iron may contain higher lead if decorated with glazed labels, but Crisbee seasoning does not compound this hazard.
Thermal decomposition of beeswax
Beeswax has a higher smoke point (around 350-400F) than many plant oils. If applied and heated well beyond typical stovetop use, it could theoretically break down into volatile compounds, but normal seasoning application involves low to moderate heat only.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 92% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
