Crisco Grill Master No-Stick Cooking Spray
Skip until Crisco discloses coating chemistry or certifies PFAS-free.
Crisco does not publicly disclose the nonstick spray coating composition or PFAS status. Traditional aerosol cooking sprays often contain Teflon-family coating; without transparency, risk cannot be ruled out.

The full breakdown
What it's made of and why it matters
Crisco Grill Master is a propellant-based cooking spray with an unspecified nonstick coating applied to food-contact surfaces. The propellant is typically hydrocarbon-based (butane/propane mixture), which is generally recognized as safe at normal use levels. The critical unknown is the nonstick coating chemistry: Crisco has not publicly disclosed whether it uses Teflon-type coating (Teflon), silicone, or another polymer, making risk assessment incomplete. This opacity is the primary safety concern.
The brand's record and disclosure
Crisco (owned by Conagra) has a long history in cooking fats and oils but has not published transparent ingredient lists or safety certifications for its spray products. The brand has not voluntarily disclosed PFAS testing results or committed to PFAS-free formulations for this line, unlike some competitors (e.g., Chosen Foods, Primal Kitchen). No major recalls or safety warnings are on record for this specific product, but the absence of proactive disclosure is notable in an industry increasingly scrutinized for fluorinated coatings.
How it compares in its category
Cooking spray hazards center on nonstick coating stability at high temperatures. Crisco's lack of disclosed coating type places it in a middle tier of transparency. Brands certified PFAS-free or using silicone-only formulations (certified by NSF or similar) offer more assurance; conventional Teflon-type coating sprays carry established Teflon-type coating fume risk above 500F. Crisco's positioning as a general-purpose grill spray without heat-limit disclosure is a red flag relative to products with explicit temperature guidance.
If you buy it
Use only on low to medium-heat cooking surfaces; avoid preheating empty pans or grill grates to high temperatures before spraying. Apply thin, even coats and allow solvent to evaporate before heating. Do not use on surfaces that will exceed 400F (e.g., direct grill flames, broiler). Replace if the nonstick coating visibly wears, flakes, or degrades. Prioritize brands with published coating chemistry and PFAS certification if you cook regularly at high temperatures.
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.”
Teflon-type coating thermal degradation / fume inhalation risk
If the coating is Teflon-type coating-based (not disclosed), heating above 500F can release toxic fumes (Teflon-type coating polymer fume fever). Crisco does not specify temperature limits or coating material, leaving this risk unquantified.
Coating degradation and ingestion of microparticles
Spray coatings are thin and prone to wear with repeated use and abrasion. Flaking or peeling nonstick layers could contaminate food; without knowledge of coating binder chemistry, secondary health effects are unclear.
Propellant inhalation during use
Hydrocarbon propellants in typical cooking sprays are volatile but not classified as toxic at typical spray exposure levels. No adverse effects are well documented for Crisco spray specifically at normal kitchen use.
Silicone residue accumulation (if silicone-based coating)
Some cooking sprays use silicone oils as nonstick agents. Repeated use can leave residue on cookware or pans, potentially interfering with seasoning or creating build-up; unknown if Crisco formulation includes silicone.
Aluminum leaching from pan surfaces (indirect)
The spray itself does not leach aluminum, but acidic or high-temperature cooking on bare aluminum can be accelerated by oil contact; no hazard unique to this product brand.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 35% 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.
