Coconut Oil · Cast Iron Cookware Seasoning & Oil
Great Value Organic Naturally Refined Coconut Oil
Lower concern; edible oil, not cookware equipment.
Refined coconut oil is food product, not cookware equipment, with minimal PFAS risk under normal use. No coating or treatment introduces PFAS.

Refined coconut oil, edible liquid
Brand disclosure

Lab data
No public lab test
What’s concerning
Category baseline
PFAS exposure happens more often with clothing products.
Thermal degradation and oxidation products
Refined coconut oil can break down into aldehydes and other oxidation byproducts if heated above its smoke point or stored improperly, though this is a normal risk for any cooking oil and is not specific to this brand.
Lead
Coconut palms grown in contaminated soil can accumulate naturally occurring heavy metals; Great Value does not publicly disclose testing for these contaminants, so risk cannot be quantified. Organic certification does not exclude heavy metals.
Source: ATSDR ↗Pesticide residue
Although labeled organic, no third-party residue testing is disclosed on packaging. Organic coconut oils still require compliance with USDA organic standards, but independent verification is not confirmed for this product.
Source: EPA ↗Rancidity and mold if stored improperly
Refined coconut oil can develop off-odors, off-flavors, or visible mold if exposed to heat, light, or humidity; this is a storage issue rather than a manufacturing defect but can render the oil unsafe to consume.
What’s reassuring
Safe base material
Made from ceramic, mineral, or natural fiber with no PFAS risk.
Allergen labeling gaps
Coconut oil is tree-nut derived; packaging should clearly state this for individuals with tree-nut allergies. No specific labeling failures for Great Value have been reported, but consumers with allergies should verify the label.
The full breakdown
What it's made of and why it matters
Great Value Organic Naturally Refined Coconut Oil is extracted from coconut meat and processed to remove odor and some impurities while retaining the fatty acid profile. Refined coconut oil has a higher smoke point (around 350-400°F / 175-204°C) than virgin coconut oil, making it more suitable for cooking. The refining process uses heat and mechanical separation, not chemical solvents in most commercial refined coconut oils, though this should be confirmed on the label. As an edible fat, it does not interact with cookware the way non-stick coatings or ceramic glazes do, so typical cookware hazards (lead, cadmium, Teflon-type coating fume risk) do not apply.
The brand's record and disclosure
Great Value (Walmart's private label) has not published specific safety disclosures or third-party certifications for this coconut oil product beyond the 'Organic' claim, which is USDA-regulated but does not address processing residues or contaminant testing. No recalls specific to Great Value coconut oil have been widely reported in FDA records. The brand does not publicly disclose heavy metal testing, pesticide residue limits, or refining methods on packaging, which is typical for commodity oils but limits transparency. Buyers relying on organic certification alone should note that organic status does not guarantee absence of naturally occurring contaminants like arsenic or lead in tropical crops.
How it compares in its category
Refined coconut oil is safer for moderate-heat cooking than virgin varieties because it tolerates higher temperatures without degrading or producing off-flavors. Compared to other refined vegetable oils (canola, soybean, sunflower), coconut oil has a similar safety profile in terms of chemical hazards, though coconut's saturated fat content is higher. Third-party tested coconut oils (from brands like Nutiva or Tropical Traditions) may offer more transparency on heavy metal and pesticide testing, but Great Value's lower cost reflects less rigorous public disclosure rather than confirmed poor quality. For general cooking use, Great Value's price and organic status make it competitive; buyers prioritizing verified safety testing should consider premium brands.
If you buy it
Store in a cool, dark place away from direct light to prevent oxidation and rancidity; refined coconut oil is stable at room temperature but will degrade if exposed to heat or sunlight over time. Use for cooking at temperatures below 375°F (190°C) to avoid exceeding the smoke point, which generates unhealthy compounds and smoke. Replace the bottle if the oil develops an off smell, discoloration, or visible mold, which signals rancidity or contamination. Limit use in high-heat applications like deep frying; reserve for sautéing, baking, or low-to-medium heat cooking.
