Stayfree Maxi Regular 10 Count (Pack of 2)
Skip until brand discloses waterproof backing chemistry; menstrual products touching skin warrant PFAS transparency.
Stayfree Maxi lacks any public disclosure of PFAS or waterproof-backing composition. Menstrual pads typically use polymer films for leak protection, a known PFAS-risk category, yet the brand offers no third-party testing or certification. Without independent lab data or brand commitment to PFAS-free materials, confidence remains low.

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.
