Kotex Natural Maxi Protect Thick Pads 100% Cotton
Lower-concern choice; cotton core is PFAS-resistant but backing composition lacks transparency.
Kotex Natural's 100% cotton claim on the absorbent layer is a positive signal, cotton itself does not require PFAS treatment. However, the brand does not disclose what adhesive or backing materials are used, which is where PFAS exposure in period products typically occurs.

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
The core is 100% cotton, which is inherently low in synthetic additives and does not require chemical treatment for absorbency. The adhesive backing material is not disclosed by Kotex, a common gap in the industry; backing adhesives can contain acrylates, tackifiers, or proprietary blends that may include processing residues. The top sheet (typically nonwoven) is also unspecified, though most period pads use polyester or polypropylene in contact with skin. Cotton as the absorbent layer is a genuine advantage over superabsorbent polymer (SAP)-only designs, which carry microplastic and chemical contamination risk.
The brand's record and disclosure
Kotex Natural is marketed as a 'natural' alternative within the Kotex family but does not publish full material composition, safety certifications, or independent testing results. The brand has not issued public statements on PFAS, phthalates, or other chemical testing, placing it in the silent/minimal-disclosure category typical of major period-pad manufacturers. No recalls or safety incidents specific to this product are on record. The 'Natural' label is a marketing claim rather than a certified standard (e.g., no organic certification or third-party chemical audit).
How it compares in its category
Most conventional period pads rely heavily on superabsorbent polymers and polyacrylates with minimal cotton, making the 100% cotton core genuinely differentiated. Competitors like Cora, Rael, and some store-brand 'organic' options also highlight cotton content, but Kotex Natural's market penetration and retail availability are higher. Chlorine-bleached conventional pads pose higher dioxin and chlorine residue risk; this product does not advertise bleaching method. The lack of adhesive/backing transparency is standard across the category, not specific to Kotex, but it remains a gap.
If you buy it
Store in a cool, dry place away from direct sunlight to prevent adhesive degradation and moisture absorption that can breed bacteria. Change pads every 4-8 hours depending on flow; extended wear increases bacterial colonization risk on any pad regardless of material. Inspect each pad before use for any visible degradation, adhesive peeling, or discoloration, which would indicate moisture exposure during storage or manufacturing defect. If you experience skin irritation, discontinue and test with a different pad design or material, as individual sensitivity to cotton quality, adhesive residue, or top-sheet material varies widely.
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.”
Adhesive backing composition (unspecified)
Kotex does not disclose the adhesive or backing material; typical pad adhesives may contain acrylate polymer residues or tackifiers that can leach onto skin with prolonged contact or heat. No testing data is public for this specific formulation.
Chlorine residues (bleaching method undisclosed)
The product does not specify whether the cotton core is chlorine-bleached, oxygen-bleached, or unbleached. Chlorine-bleached cotton can retain trace dioxins; no independent testing of this brand is available to confirm bleaching standard.
Skin sensitization from nonwoven top sheet
The top sheet material is not disclosed; most pads use polyester or polypropylene, which are generally low-irritant but can carry residual polymeric additives or finishes. Individual sensitivity is common and not product-specific, but lack of transparency limits pre-purchase risk assessment.
Microplastic shedding from backing or top layer
The 100% cotton core itself does not shed microplastics. Non-cotton layers (backing, top sheet) are undisclosed; if synthetic, degradation over storage or use could release fibers, but no reported incidents for this product.
Bacterial growth from moisture retention
All absorbent period pads create a moist microenvironment; extended wear, humid storage, or poor hygiene during handling can promote bacterial colonization regardless of material. This is a use-practice hazard, not unique to Kotex Natural, but relevant to safe handling.
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.
