Basecoat & Sealer Nail Polish vs HARD AS NAILS XTREME WEAR NAIL: 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 Sally Hansen.
• We flag Volatile organic solvents (toluene, xylene, camphor), Phthalate plasticizers (likely dibutyl phthalate or replacement), Formaldehyde in resin binders and Allergic sensitization to fragrance or dyes on the Sally Hansen and not on the Piggy Paint.
• The Piggy Paint is Water-based organic pigments and plant-derived resins where the Sally Hansen is nitrocellulose lacquer, plasticizers, resins (typical nail polish formulation), 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 Sally Hansen grade, at 45% confidence against 82%, because it discloses less.
