PFAS score
Butter London · Nail Polish
butter LONDON Pure Color 21X Nail Lacquer
No public PFAS risk data; nail lacquers rarely contain PFAS, but Butter London makes no disclosure, skip only if PFAS-free verification matters to you.
Butter London does not publicly disclose PFAS status for this nail lacquer. Nail polish formulations typically do not require PFAS for function, but the brand's silence means no third-party assurance. If PFAS-free certification is important, request explicit documentation or choose a brand with verified PFAS-free claims.

What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 45% 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.
