Where these two actually differ
- We flag Alcohol inhalation from spray, Fragrance allergens and sensitizers and Resin irritation on compromised skin on the MAC and not on the Sally Hansen.
- We flag Volatile Organic Compounds (VOCs) and inhalation risk, Phthalates (plasticizers), Formaldehyde releasers in resins and Contact sensitization from fragrance or colorants on the Sally Hansen and not on the MAC.
- The MAC is liquid cosmetic spray, alcohol and resin based where the Sally Hansen is nitrocellulose, plasticizers, resins, pigments, which is most of the difference in these two grades.
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 →
