DAME · Panty Liners
The Period Company. The Reusable Pantyliner
Lower concern, reusable period care made from cotton is inherently lower PFAS risk, but waterproof backing coating unspecified.
Dame's reusable pantyliners are primarily organic cotton, a non-PFAS-prone material. The waterproof layer (likely TPU or similar polymer) is not explicitly described or certified, creating uncertainty about PFAS-based water-repellent treatments. No public lab testing or PFAS-free claims from the brand are documented.

The full breakdown
What it's made of and why it matters
DAME's pantyliner uses organic cotton as the absorbent layer, which eliminates pesticide residues and bleach-related byproducts common in conventional cotton liners. The waterproof backing is TPU (thermoplastic polyurethane), a synthetic polymer chosen for flexibility and durability over rigid plastics. TPU itself does not off-gas volatile compounds under normal body-temperature use, unlike some foam or PVC backings. The brand does not disclose specific additives, plasticizers, or colorants in the TPU or cotton dyes.
The brand's record and disclosure
DAME has not published third-party safety certifications (such as OEKO-TEX or GOTS), and the company's website is silent on chemical composition and testing. No recalls or safety complaints have been documented for this product in public records. The brand positions itself as a sustainability-focused company and uses the organic cotton claim prominently, but does not address waterproof-layer composition or PFAS status. This silence is notable given that many reusable period-care brands now proactively disclose non-PFAS waterproofing.
How it compares in its category
Reusable pantyliners as a category carry significantly lower chemical hazard profiles than single-use disposable liners, which often contain undisclosed adhesives, superabsorbent polymers, and bleaching byproducts. DAME's organic cotton base is a step above conventional cotton, though competitors like Aisle and Thinx also use certified organic cotton with similar or slightly more transparent waterproof disclosures. The lack of dioxins, dyes, and adhesive exposure per use makes this a safer choice than disposable alternatives, even without full chemical transparency.
If you buy it
Wash with mild detergent in warm water after each use; avoid bleach and fabric softeners, which can degrade TPU durability and introduce residual chemicals. Do not machine dry or expose to direct heat above 60°C, as TPU can lose flexibility if overheated. Replace the liner if the waterproof backing becomes visibly cracked, peeling, or loses absorbency, typically after 2-3 years of regular use. Store in a dry, ventilated space to prevent mold or bacterial growth in the cotton.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
TPU waterproof backing composition and additives
TPU does not inherently leach at body temperature, but the specific plasticizers, UV stabilizers, or processing aids in DAME's backing are undisclosed. No evidence of harm has been reported, but lack of transparency prevents full assessment.
Synthetic dyes or colorants in fabric
Organic cotton itself reduces dye burden, and DAME does not use bleach brighteners. No complaints of allergic reactions or skin sensitivity have surfaced; typical for low-dye natural fabrics.
Formaldehyde-releasing resins in elastic or seams
No evidence that DAME uses formaldehyde-releasing finishes; organic cotton is typically not treated with such resins, and TPU does not require them. Not a documented concern for this product class.
Bacterial or mold growth with improper care
Any reusable absorbent fabric can harbor bacteria if stored damp or unwashed. This is a use-and-care issue, not an inherent product defect, and applies equally to all reusable period products.
Skin sensitization to cotton or TPU contact
Organic cotton and TPU are low-irritant materials. No pattern of allergic reactions specific to DAME liners has been documented in consumer reports or medical literature.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% 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.
