100% Natural Nourishing Mascara, Black Brown vs Inimitable Waterproof Mascara: which is safer?

Where these two actually differ

• We flag Fragrance allergens and undisclosed sensitizers and Bacterial growth and contamination in wax formula on the Burt's Bees and not on the Chanel.
• We flag Undisclosed waterproofing agent (potential PFAS exposure), Formaldehyde releasers in film-forming polymers, Lash follicle irritation from waterproof removal friction and Fragrance allergens or undisclosed fragrance components on the Chanel and not on the Burt's Bees.
• The Burt's Bees is Wax, pigments, natural oils (typical mascara base) where the Chanel is wax/film-forming polymers with waterproofing agent (unspecified), 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 Chanel grade, at 35% confidence against 78%, because it discloses less.
