Patent Shine 10X Nail Lacquer vs Basecoat & Sealer Nail Polish: which is safer?

Where these two actually differ

• We flag Heavy metals in synthetic pigments, Fragrance allergens from added scents and PFAS in coating resins or additives on the Butter London and not on the Piggy Paint.
• We flag Heavy metals in organic pigments and Bacterial or fungal growth in water-based formula on the Piggy Paint and not on the Butter London.
• Both carry a flag for Volatile organic compounds (VOCs) from solvents, so neither choice avoids it.
• The Butter London is nail lacquer (film-forming resins, solvents, pigments) 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 Butter London grade, at 35% confidence against 82%, because it discloses less.
