Soybean Oil · Cast Iron Cookware Seasoning
Lodge Canola Oil Seasoning Spray 8 fl oz
Lower concern. Liquid cooking oil, not a PFAS-risk product category.
This is a cooking spray of soybean oil, not a coated cookware item. Liquid cooking oils are not a PFAS-risk product category and do not require special coatings or treatments associated with forever chemicals.

Category baseline
cookware is a category where PFAS exposure is more common.
The full breakdown
What it's made of and why it matters
This product is soybean oil dispensed as a cooking spray, likely with a propellant (typically butane or similar food-grade gas) and possibly a small amount of lecithin as an anti-caking agent. Unlike non-stick cookware coatings (Teflon-type coating), solid enamels, or ceramic surfaces, liquid oils do not degrade into harmful fumes, leach heavy metals, or shed microparticles during normal use. Soybean oil itself is a standard food ingredient with no known acute chemical toxicity concerns at cooking temperatures.
The brand's record and disclosure
Lodge is a well-established US cast-iron cookware manufacturer, not primarily an oil producer; this soybean oil product appears to be a cookware care product line extension. Public disclosure on sourcing, refining, or third-party testing of the oil itself is limited. No major recalls or safety controversies tied to Lodge cooking oils are on record. The brand does not routinely publish PFAS or contaminant testing for liquid oil products, which is typical for this product category.
How it compares in its category
Cooking oil sprays occupy a lower-risk category than non-stick coated cookware, ceramic-coated cookware, or enameled cast iron, because the product itself is not a surface coating that can degrade or leach. Compared to other spray oils, soybean-based formulations are chemically stable and widely used; some alternatives use higher-smoke-point oils (avocado, grapeseed) but offer no safety advantage for a spray application. The propellant system is the primary variable; food-grade propellants are regulated and generally safe.
If you buy it
Store in a cool, dark place to minimize oxidation and rancidity, which can degrade flavor and nutritional quality over time. Use at temperatures below soybean oil's smoke point (around 450F) to avoid degradation and off-flavors; spray application reduces actual contact temperature on cookware. Replace if the bottle leaks, the propellant fails, or the oil develops a musty or off-smell, which signals oxidation. No special maintenance required beyond normal storage practices.
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.”
Oil oxidation and rancidity
Liquid soybean oil can oxidize over time, especially if stored in warm or light conditions, producing off-flavors and potentially harmful peroxide compounds. This is a degradation issue rather than a formulation hazard and is managed by proper storage.
Propellant safety
Food-grade propellants in spray cans (butane, propane, nitrogen) are regulated and do not pose inhalation or contamination risks at normal use volumes. No hazards specific to Lodge's spray formulation are on record.
Allergen presence (soy protein residue)
Highly refined soybean oil contains minimal soy protein and is generally safe for soy-allergic individuals, but trace proteins may remain depending on refining method. Individuals with severe soy allergies should verify the product's allergen statement or contact the manufacturer.
Mineral oil or silicone contaminants
No public reports of mineral oil, silicone, or other non-oil contaminants in Lodge soybean oil sprays. Food-grade oils sold in the US are subject to FDA oversight, which limits such adulterants.
Lead or cadmium in bottle/packaging
The metal spray canister is food-contact compliant and not a known source of heavy metal leaching. This hazard is relevant to ceramic or enameled cookware, not liquid oil packaging.
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.
