Where these two actually differ

  • 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 Sinful Colors.
  • We flag Phthalates (plasticizers), Volatile organic compounds (VOCs) and toluene/xylene, Heavy metals in pigments (lead, cadmium) and Camphor in nitrocellulose resins (CNS/respiratory effects) on the Sinful Colors and not on the Piggy Paint.
  • The Piggy Paint is Water-based organic pigments and plant-derived resins where the Sinful Colors is nitrocellulose, plasticizers, resins (typical nail lacquer), 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 Sinful Colors grade, at 35% 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 →
