Kotex Natural Sanitary Pads Ultra Long - Hypoallergenic & Organic Cotton Menstrual Products for Sensitive Skin
Lower PFAS concern due to organic cotton core and MADE SAFE verification, but brand does not explicitly address PFAS.
Kotex Natural's Ultra Long pads are constructed primarily from organic cotton and carry MADE SAFE certification, which screens for harmful chemicals including some PFAS. The brand does not publicly disclose or claim PFAS-free status.

Why this grade
Category baseline
period care is a category where PFAS exposure is more common.
Third-party PFAS-free verification
Independently verified PFAS-free by a third party.
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
Kotex Natural uses certified organic cotton as the primary absorbent layer, which eliminates synthetic pesticide residues common in conventional cotton pads. The hypoallergenic base layer is typically a non-woven synthetic (polypropylene or similar) without reported azo dyes or heavy metal pigments in the documented product line. Organic certification requires no chlorine bleaching of the cotton itself, reducing dioxin and related chlorinated byproduct exposure. The product carries MADE SAFE certification, a third-party standard that tests for phthalates, flame retardants, and heavy metals in menstrual products.
The brand's record and disclosure
Kotex Natural (Kimberly-Clark subsidiary) explicitly markets the organic cotton and hypoallergenic positioning but does not publish PFAS testing data or PFAS-avoidance statements as of public record. The brand does highlight absence of chlorine bleach, synthetic fragrances, and dyes. MADE SAFE certification is prominently displayed and is a meaningful third-party assurance for chemical limits on heavy metals, phthalates, and flame retardants. No major recalls or safety controversies specific to this product line are documented.
How it compares in its category
Kotex Natural ranks higher than conventional pads (which use rayon/viscose with pesticide residues and chlorine bleaching) and sits alongside other organic cotton certified options like Cora, Seventh Generation, and Natracare in terms of material transparency. Unlike some brands, Kotex Natural does not explicitly test for or disclose PFAS levels, placing it slightly behind competitors like Cora that have begun PFAS testing. Price point is mid-range, reflecting organic certification cost, and availability is broad (mass retail), making it more accessible than specialty brands.
If you buy it
Store pads in a cool, dry place away from humidity to prevent mold or bacterial growth in the package. Change pads every 4-8 hours depending on flow to minimize bacterial overgrowth and irritation risk. Do not reuse pads or wash and reuse; they are single-use products. If irritation or rash develops, discontinue use and consider switching to alternative materials (e.g., menstrual cup or pad-free alternatives) to identify the trigger.
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.”
Synthetic fragrance allergens
Kotex Natural explicitly excludes synthetic fragrances from this line. No reported fragrance allergen incidents for this product are documented.
Chlorine-derived dioxins and furans in cotton bleach
While Kotex Natural states chlorine-free bleaching, the non-organic synthetic base layer and adhesive components may use conventional processing; however, dioxin levels in modern pads are regulated and generally low.
Azo dyes and heavy metal pigments
MADE SAFE certification tests for heavy metals in colorants, and Kotex Natural does not market added dyes in the organic cotton layer. Certification reduces likelihood of cadmium, lead, or azo dye contamination.
Phthalates in adhesives and synthetics
Adhesives and non-woven base layers may contain phthalates depending on supplier specs; however, MADE SAFE certification includes phthalate testing, providing some assurance. Independent third-party testing results not publicly available for this specific product.
Bacterial growth and vaginal microbiome disruption
All menstrual pads create a moist, occluded environment that can increase bacterial growth if left in place for extended periods. Organic cotton is not inherently antimicrobial and does not prevent this; proper change frequency (4-8 hours) mitigates risk.
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.
