Chromaline Gel - Hi-Def Cyan vs | 24/7 Glide-On Waterproof Eyeliner Pencil | Shade: Zero – Black Matte | 0.04 ONZ: 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 Urban Decay.
• We flag Fluorochemicals (PFAS) in waterproofing, Fragrance allergens and sensitizers and Mechanical injury from pencil shape and sharpening on the Urban Decay and not on the MAC.
• The MAC is gel pigment formulation (primary ingredients not publicly disclosed for proprietary reasons) where the Urban Decay is wax/pigment pencil with waterproof treatment (formulation undisclosed), 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.
