Rael Reusable Organic Cotton Panty Liners
Lower concern; organic cotton panty liners unlikely to contain PFAS.
Rael's reusable organic cotton liners use inherently lower-concern materials. Brand does not disclose PFAS testing or claims, but cotton and rubber are not typical PFAS application areas.

What Rael Reusable Organic Cotton Panty Liners is made of, ingredients and materials
Rael panty liners are constructed from organic cotton and natural rubber, both minimally processed materials with lower chemical load than conventional alternatives. Organic cotton excludes synthetic pesticides and certain fertilizers used in conventional cotton production, reducing residue risk. Natural rubber is a plant-derived elastomer without the synthetic polymer or plasticizer burden of petroleum-based alternatives; it requires vulcanization (sulfur curing) but does not involve phthalates or bisphenols by standard formulation.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Formaldehyde / VOCs
Conventional cotton often uses formaldehyde-based resins for wrinkle resistance or sizing; organic cotton typically avoids these, but Rael does not publish finished-product formaldehyde testing or finish specifications. Risk is lower than conventional but not ruled out without third-party lab data.
Source, ATSDR ↗Azo dyes and synthetic colorants
If liners are dyed or patterned, azo dyes (which can release carcinogenic amines under certain conditions) are a concern. Rael does not disclose dye chemistry or whether suppliers meet Oeko-Tex Standard 100 or similar restrictions. Organic certification does not mandate azo-dye exclusion.
Bacterial and fungal growth from reuse without proper hygiene
Reusable menstrual products accumulate microorganisms if not washed promptly or dried thoroughly. This is a use-practice hazard, not a manufacturing hazard, but critical to managing product safety. TSS (toxic shock syndrome) is associated with staphylococcal overgrowth in damp fibrous materials.
Residual sulfur and sulfur compounds from rubber vulcanization
Natural rubber vulcanization uses sulfur or accelerants; finished rubber may contain trace sulfur that could irritate sensitive skin on contact. Rael does not publish vulcanization protocols or post-cure residual-sulfur testing. Dermal sensitization or irritation is not on record but cannot be ruled out.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Heavy metals
Soil uptake of cadmium, lead, or arsenic in cotton and rubber crops is documented in agricultural contexts, but no recalls or testing results specific to Rael liners have been published. Organic farming standards reduce synthetic inputs but do not eliminate heavy-metal bioaccumulation risk entirely.

The brand's record and disclosure
Rael markets organic cotton period products as a cleaner alternative and provides basic material disclosure on packaging. The brand does not publish detailed third-party certifications (such as GOTS, Oeko-Tex, or heavy metal testing reports) on its public materials. No recalls, safety controversies, or regulatory actions specific to this product have been recorded. Transparency on dye sources, adhesive composition, or residual sulfur levels from rubber vulcanization is not publicly documented.
How it compares in its category
Organic cotton liners sit at the lower-chemical end of the reusable menstrual-product spectrum. Most conventional disposable liners use bleached rayon or bleached cotton with synthetic adhesives and often include plastic-backing films; some contain plasticizers or legacy flame retardants. Rael's organic cotton and natural rubber positioning avoids those widely documented exposures. Reusable textile liners in general eliminate single-use plastic waste but require laundering discipline to prevent bacterial growth.
If you buy it
Wash liners in hot water after each use and dry fully before reuse to prevent bacterial or fungal colonization. Machine wash on gentle cycle is acceptable; tumble dry on low or air dry. Replace liners if rubber loses elasticity, cotton shows visible wear, or odor persists after proper washing. Store in a clean, dry pouch or container, not in a sealed damp bag between uses.
