Chromaline Gel - Hi-Def Cyan vs 24/7 Glide On Waterproof Eye Pencil: which is safer?
Chromaline Gel - Hi-Def Cyan is the clear pick. Urban Decay 24/7 Glide On Waterproof Eye Pencil carries a failing PFAS grade, and we never recommend buying a failing product.

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 Heavy metals in pigments (lead, cadmium, iron oxides), Fragrance allergens and undisclosed fragrance constituents and Polymer coating degradation and microplastic shedding with use 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 film-forming polymer, 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.
Both products run through the same public rubric: materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
