100% Natural Nourishing Mascara, Black Brown vs Perversion Mascara Travel: 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 Formaldehyde or formaldehyde-releasing preservatives, Heavy metals in colorants (iron oxides, titanium dioxide, mica), 1,4-dioxane residue in emulsifiers and Fragrance allergen sensitivity 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 mascara formula with waterproof treatment, 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 45% confidence against 78%, because it discloses less.
