What Crisbee Puck Cast Iron Seasoning is made of, ingredients and materials
Puck is a blend of soybean oil and beeswax, designed to polymerize on cast iron when heated to form a non-stick seasoning layer. Soybean oil is a triglyceride-based food-grade oil with a smoke point around 450F, suitable for seasoning applications. Beeswax acts as a hardening agent that helps the oil cure into a durable finish. This formulation contains no synthetic coatings, Teflon-type coating (Teflon), or nano-particles, making it chemically straightforward.
What’s concerning
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
Soybean oil oxidation and rancidity
Unopened pucks have minimal exposure, but once opened, the exposed soybean oil surface can oxidize over months, potentially producing off-odors or degraded flavor if used on food-contact surfaces. Proper storage in a cool, sealed container mitigates this.
Beeswax purity and contaminants
Commercial beeswax can occasionally contain residual pesticides (from hive treatments) or mold if sourced from poor storage conditions. The brand does not disclose beeswax sourcing or testing; risk is low but unverified.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Smoke point and thermal breakdown
Soybean oil's 450F smoke point is adequate for the recommended seasoning oven temperatures (350-500F). No safety hazard is documented when used as directed, though excessive heating beyond 500F could degrade the oil base.
Coating durability and iron leaching
The seasoning layer created by soybean oil-beeswax polymerization protects cast iron from contact with food and liquids, preventing iron oxidation and leaching. No mechanism for hazardous leaching exists with this formulation.
Allergen content (soy, bee products)
The brand is not ingested; it remains as a dry, cured coating on cookware. Soybean oil and beeswax are not absorbed into food during normal use, so soy or bee allergies pose no risk from the seasoning itself.
How is this PFAS grade calculated?
The brand's record and disclosure
The brand has maintained a low public profile with minimal formal certifications or third-party testing disclosures. The product has no documented recalls, safety warnings, or controversy in available safety databases. The brand does not explicitly market PFAS-free status but the formulation (traditional oils and wax) inherently excludes PFAS compounds used in modern non-stick coatings.
How it compares in its category
Cast iron seasoning products typically fall into two camps, oil-based blends (like the brand) or proprietary sprays that may contain additives or polymers. The brand's soybean oil-beeswax approach is more minimal than spray seasonings and avoids synthetic polymers or silicone carriers found in some competitors. It matches the safety profile of traditional seasoning methods (cooking oil alone) but with added durability from beeswax.
If you buy it
Apply thin coats to clean, dry cast iron and wipe away excess before heating to 350-500F in an oven for 15-30 minutes per layer. Do not use on stovetop directly as oil can ignite. The soybean oil base will not degrade the cast iron; beeswax will not flake if applied correctly. Reapply every 6-12 months or after heavy use; no special removal is needed for reapplication.
