Where these two actually differ

- We flag Oxidative degradation and rancidity and Allergen contamination (sesame) on the Sesame Oil and not on the Crisbee.
- The Crisbee is Organic waxes and oils blend where the Sesame Oil is Sesame oil, liquid, which is most of the difference in these two grades.
Both products run through the same public rubric, which covers 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 →
