Le Vernis Longwear Nail Colour - One size vs Basecoat & Sealer Nail Polish: which is safer?

Where these two actually differ

• We flag Phthalates (plasticizers), Formaldehyde and formaldehyde resins, Volatile organic compounds (VOCs) and inhalation risk and Fragrance allergens on the Chanel 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 Chanel.
• The Chanel is nitrocellulose lacquer-based nail polish with resins and plasticizers 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 Chanel grade, at 45% confidence against 82%, because it discloses less.
