PFAS score
Kotex · Period Pads
U by Kotex Clean & Secure Ultra Thin Pads
Skip until Kotex discloses waterproof layer chemistry, period pads often use fluorinated coatings to repel moisture.
U by Kotex does not publicly disclose the chemical composition of the waterproof backing on these ultra-thin pads. Period care products commonly rely on fluorinated treatments (PFAS) for leak-resistance, and Kotex has not claimed PFAS-free status or provided third-party verification.

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.
