Where these two actually differ
- We flag Undisclosed waterproofing agents (possible PFAS or polymer residues), Bacterial or fungal contamination from liquid formula over time and Eye irritation or allergic reaction from fragrance or essential oils on the Bobbi Brown and not on the Burt's Bees.
- We flag Fragrance allergens and undisclosed sensitizers and Bacterial growth and contamination in wax formula on the Burt's Bees and not on the Bobbi Brown.
- The Bobbi Brown is Liquid pigment blend, waterproofing agents unspecified where the Burt's Bees is Wax, pigments, natural oils (typical mascara base), which is most of the difference in these two grades.
- The gap is 45 points, wide enough that this is not a close call, and the Burt's Bees is the one to buy.
- We are less certain about the Bobbi Brown 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 →
