China Glaze Nail vs Basecoat & Sealer Nail Polish: which is safer?

Where these two actually differ

• We flag Volatile Organic Compound (VOC) inhalation during application, Phthalate presence (dibutyl phthalate or similar plasticizers), Heavy metal pigments (lead, cadmium, chromium in colorants) and Fragrance allergens (if scented formula) on the China Glaze 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 China Glaze.
• The China Glaze is nitrocellulose lacquer & resin film (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 China Glaze grade, at 35% confidence against 82%, because it discloses less.
