100% Natural Nourishing Mascara, Black Brown vs Perversion Volumizing 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 Urban Decay.
• We flag PFAS in film-formers (fluorinated polymers or aqueous coatings), 1,4-dioxane contamination (manufacturing byproduct), Formaldehyde releasers (preservative systems) and Heavy metals in pigments (iron oxides, carbon black) on the Urban Decay and not on the Burt's Bees.
• The Burt's Bees is Wax, pigments, natural oils (typical mascara base) where the Urban Decay is waterproof mascara formula with unspecified coating/resin system, 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 Urban Decay grade, at 35% confidence against 78%, because it discloses less.
