PFAS score
Butter London · Nail Polish
Butter London Patent Shine 10X Nail Lacquer
Skip until brand discloses PFAS status; nail lacquers rarely need PFAS but opacity is a red flag.
Butter London does not publicly disclose PFAS content or absence in this nail lacquer. Nail polish formulations rarely require PFAS, but without third-party testing or a manufacturer statement, the risk profile remains unknown. Safer alternatives exist from brands that test or certify PFAS-free.

What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 35% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
