Where these two actually differ

  • We flag Phthalates (plasticizers), Volatile organic compounds (VOCs) and respiratory irritation, Formaldehyde and formaldehyde releasers and Heavy metal residues in resins or processing aids on the Dior 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 Dior.
  • The Dior is Nail polish base coat (likely nitrocellulose, resins, plasticizers) 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 Dior 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 →
