Where these two actually differ
- We flag Oil rancidity and off-gassing and Allergen risk from plant oils on the Crisbee and not on the Crisco.
- We flag PTFE thermal degradation / fume inhalation risk, Coating degradation and ingestion of microparticles and Silicone residue accumulation (if silicone-based coating) on the Crisco and not on the Crisbee.
- The Crisbee is Organic waxes and oils blend where the Crisco is propellant spray with unspecified nonstick coating, which is most of the difference in these two grades.
- The gap is 70 points, wide enough that this is not a close call, and the Crisbee is the one to buy.
- We are less certain about the Crisco grade, at 35% confidence against 78%, because it discloses less.
Both products run through the same public rubric: materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
