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 MAC.
- We flag Formaldehyde releasers or preservative sensitivity, Fragrance allergens and contact sensitization and Irritation from waterproofing agents and occlusion on the MAC and not on the MAC.
- The MAC is gel pigment formulation (primary ingredients not publicly disclosed for proprietary reasons) where the MAC is Pigments, waxes, oils in pencil/kohl format with waterproofing agents, 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 MAC grade, at 35% confidence against 65%, because it discloses less.
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 →
