DAME Reusable Period Liner
Lower PFAS concern, but waterproofing layer unspecified, request transparency from Dame.
DAME Reusable Period Liners are primarily organic cotton, a low-risk base material for PFAS. However, the brand does not publicly disclose the composition of its waterproof backing layer, which is a common vector for PFAS coatings in water-resistant textiles. No third-party PFAS testing or certification is evident.

Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
The full breakdown
What it's made of and why it matters
DAME Reusable Period Liners use organic cotton for the absorbent layer, which avoids synthetic pesticide residues and is inherently breathable. The critical unknown is the waterproof backing: DAME does not publicly specify whether it uses polyurethane, rubber, or a coated polymer. This matters because some waterproof coatings contain plasticizers (phthalates) or flame retardants that can leach with repeated washing and contact with skin. Without disclosure, you cannot assess the coating's safety profile.
The brand's record and disclosure
DAME Products markets itself as a sustainability and health-focused brand but has not published material safety data sheets (MSDS) or independent certifications (GOTS, OEKO-TEX) for the liners on their website. The brand remains silent on waterproof layer composition and PFAS use, which are standard transparency expectations for period products. No recalls or adverse event reports are on record, but absence of disclosure is a compliance and trust gap for a premium-priced product.
How it compares in its category
Reusable period liners are safer than disposable alternatives in that they avoid dioxins and chlorine bleaching, but transparency varies widely. DAME's lack of coating disclosure is a weakness compared to competitors like Thinx or Modibodi, which explicitly state polyurethane or TPU (thermoplastic polyurethane) construction. Organic cotton backing is a strength, but it does not offset vagueness about the waterproof layer, which is the likeliest source of chemical leachates.
If you buy it
Contact DAME directly to request the waterproof coating material before ordering. Wash in cold water with mild detergent and air-dry; heat (dryer, hot water) can accelerate coating breakdown and leaching. Replace liners if the waterproof layer begins to crack, peel, or lose water resistance, as degradation increases skin contact with raw coating materials. Store in a breathable pouch to prevent mold and bacterial growth between uses.
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.”
Plasticizers in polyurethane or PVC waterproof coatings
If the waterproof backing uses phthalate-plasticized PVC or polyurethane, repeated washing and direct skin contact (especially in warm, moist conditions) can leach phthalates. DAME has not disclosed the coating type, making this assessment speculative but plausible for reusable period products.
Flame retardants in synthetic waterproof layer
Some polyurethane or rubber coatings may contain brominated or phosphate-based flame retardants for regulatory compliance. These are not typically added to textiles below 10 microns, but thicker waterproof backings could pose a minor risk if not explicitly excluded by the manufacturer.
Coating degradation and microparticle shedding
Reusable period liners experience repeated mechanical stress (washing, stretching) and moisture exposure. As the waterproof layer ages, it can shed microparticles or flake; without knowing the coating material, you cannot assess whether these particles are benign (silicone) or problematic (PVC fragments).
Formaldehyde in organic cotton finishing or elastic
DAME uses organic cotton, which avoids synthetic pesticides, but some organic certifications still allow low-level formaldehyde resin finishes for wrinkle resistance or elastic stability. No evidence suggests DAME uses this, but GOTS certification would guarantee avoidance; lack of certification leaves this unconfirmed.
Bacterial or fungal growth if not dried thoroughly
Reusable period liners retain moisture if air-dried incompletely or stored in humid conditions. The organic cotton layer is susceptible to mildew; the waterproof backing can trap moisture. Proper drying and breathable storage are essential to prevent skin irritation or infection, independent of material chemistry.
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.
