Basecoat & Sealer Nail Polish vs Color Therapy 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 Sally Hansen.
• We flag Volatile organic compounds (VOCs) / solvent inhalation, Phthalates (dibutyl phthalate, other plasticizers), Formaldehyde and formaldehyde releasers and Coating degradation and safety over time 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 nail polish base (nitrocellulose, plasticizers, 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 Sally Hansen grade, at 45% confidence against 82%, because it discloses less.
