Auden Women's Absorbent Seamless Hipster Period Underwear
Skip until Auden discloses coating chemistry or provides third-party PFAS testing.
Auden's period underwear uses water-resistant and stain-resistant treatments typical of absorbent menstrual products, but the brand provides no public disclosure of coating materials or PFAS content. Synthetic fiber blends with performance finishes carry inherent PFAS risk without transparent testing or certification.

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.
