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

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 Volatile organic solvents (toluene, xylene, formaldehyde), Phthalate plasticizers (dibutyl phthalate or replacement esters) and Formaldehyde release from resins or hardeners 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 nail lacquer (resin, plasticizers, solvents), 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 45% confidence against 82%, because it discloses less.
