Where these two actually differ
- We flag Volatile Organic Compounds (VOCs), Dibutyl phthalate (DBP) and other plasticizers, Formaldehyde or formaldehyde releasers and Heavy metal pigments (particularly in colored lacquers) on the Butter London 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 Butter London.
- The Butter London is nail polish/treatment lacquer (typical resin/film-forming base) 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.
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 →
