Rael Micro Thin Organic Cotton Cover Panty Liners
Lower-concern product; organic cotton is inherently unlikely to contain PFAS, but no explicit brand commitment.
Rael Micro Thin liners use an organic cotton cover, a material with no known PFAS applications. The absorbent core composition is not publicly detailed, creating minor uncertainty.

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
Rael Micro Thin liners use an organic cotton cover layer, which eliminates synthetic polymer coatings (like polyethylene or polypropylene) that can leach plasticizers or degrade under moisture. The absorbent core composition is not disclosed publicly, but typical liner cores use cellulose, superabsorbent polymers (SAP), or blended materials. Organic cotton certification means the cover fibers are grown without synthetic pesticides or fertilizers, reducing dermal exposure to agrochemical residues during extended wear.
The brand's record and disclosure
Rael is a Korean-origin feminine hygiene brand with no major recalls or safety controversies on record in U.S. regulatory databases. The brand markets itself on 'clean' and organic positioning but provides minimal third-party testing data or detailed ingredient disclosure for the absorbent core. No explicit PFAS commitment or certification (e.g., OEKO-TEX, EU Ecolabel) is documented; transparency on chemical finishes or flame retardants is absent from publicly available sources.
How it compares in its category
Panty liners as a category carry lower chemical exposure risk than pads because contact time and absorbent material volume are minimal. Rael's organic cotton cover is a differentiator versus conventional liners with synthetic nonwoven covers, which may contain flame retardants or azo dyes. Most mainstream brands (Kotex, Always, Tampax) do not disclose core material details either, making Rael roughly equivalent in transparency but slightly ahead on cover material safety.
If you buy it
Replace liners every 4-6 hours or when soaked to prevent prolonged skin contact and bacterial growth risk. Store in a cool, dry location to avoid moisture accumulation in the package before use. If irritation develops (rash, itching, or discharge changes), discontinue and patch-test on a small area of skin first. Dispose in normal waste; liners are not flushable despite marketing language.
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.”
Undisclosed absorbent core chemistry
Core material is not specified by Rael; if it contains conventional superabsorbent polymers (SAP), sodium polyacrylate is generally recognized as safe but can cause irritation if exposed to abraded or sensitized skin. No testing data provided by brand.
Azo dyes in cover or core
Organic cotton cover should not contain azo dyes if certification is legitimate, but no third-party audit is documented. Core material dyes are not disclosed; conventional liners sometimes use azo dyes which can release aromatic amines under moisture and body heat.
Formaldehyde-releasing finishing agents
Organic cotton typically avoids formaldehyde resins used for wrinkle-resistance in conventional textiles, but finishing details are not published. No recall or complaint history suggests this is not a practical concern for this product.
Bacterial growth and dermatitis from occlusion
All panty liners create a moist microclimate; extended wear or infrequent changes can promote bacterial overgrowth and candida, leading to irritation or infection. This is a use-pattern hazard, not a material defect specific to Rael.
Allergic contact dermatitis from undisclosed adhesives or fragrance
Product packaging does not list adhesive composition or fragrance ingredients. Synthetic adhesives and fragrance compounds (even plant-derived) can trigger reactions in sensitive individuals; no hypoallergenic certification is claimed.
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.
