Chromaline Gel - Hi-Def Cyan vs Line Express Sharpenable Wood Pencil Eyeliner: which is safer?

Where these two actually differ

• We flag Heavy metals in colorants (iron oxides, titanium dioxide, mica), Formaldehyde releasers (preservative system), 1,4-dioxane (contaminant in polyethylene glycol or emulsifiers) and Eye irritation from film formers or fragrance compounds on the MAC and not on the Maybelline.
• We flag Heavy metals in synthetic colorants, Fragrance allergens and sensitizers, Bacterial contamination from wood casing and sharpening and Undisclosed waterproofing agents (likely PFAS) on the Maybelline and not on the MAC.
• The MAC is gel pigment formulation (primary ingredients not publicly disclosed for proprietary reasons) where the Maybelline is wood pencil with presumed waterproof pigment/wax formulation, 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 MAC is the one to buy.
• We are less certain about the Maybelline grade, at 35% confidence against 65%, because it discloses less.
