Where these two actually differ
- We flag Volatile Organic Solvent (VOC) Inhalation, Fragrance Sensitizers and Allergens and Plasticizer Leaching (Dibutyl Phthalate, DBP) on the Mavala and not on the Piggy Paint.
- We flag Heavy metals in organic pigments, Volatile organic compounds (VOCs) from solvents and Bacterial or fungal growth in water-based formula on the Piggy Paint and not on the Mavala.
- The Mavala is organic film-forming resins (typical nail lacquer) where the Piggy Paint is Water-based organic pigments and plant-derived resins, which is most of the difference in these two grades.
- The gap is 25 points, wide enough that this is not a close call, and the Piggy Paint is the one to buy.
- We are less certain about the Mavala grade, at 45% confidence against 82%, 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 →
