100% Natural Nourishing Mascara, Black Brown vs Professional 3-in-1 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 CoverGirl.
• We flag Undisclosed waterproofing chemistry (fluorinated vs. silicone polymers), Contact allergens and fragrance sensitivity, Formaldehyde releasers in preservatives and Lash and lid irritation from film buildup and removal stress on the CoverGirl and not on the Burt's Bees.
• The Burt's Bees is Wax, pigments, natural oils (typical mascara base) where the CoverGirl is wax and polymer film-forming ingredients, waterproof treatment 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 CoverGirl grade, at 35% confidence against 78%, because it discloses less.
