Chromaline Gel - Hi-Def Cyan vs Master Precise All Day Liquid Eyeliner: which is safer?
Chromaline Gel - Hi-Def Cyan is the clear pick. Maybelline Master Precise All Day Liquid Eyeliner 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 Maybelline.
- We flag Undisclosed waterproofing agents (likely PFAS-class compounds), Iron oxide or synthetic azo pigments, Preservative-related sensitivity and Microplastic particles from polymer carriers 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 liquid eyeliner with waterproof film-forming 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 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 →
