Kotex Natural Tampon Super 16
Lower concern; no confirmed PFAS risk in standard tampon materials.
Kotex Natural tampons use rayon and cotton, materials not typically treated with PFAS. No brand disclosure on PFAS, but primary materials pose lower concern than coated or waterproofed products.

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.
Bacterial contamination and toxic shock syndrome (TSS) risk
All tampons carry theoretical TSS risk tied to prolonged insertion and Staphylococcus aureus colonization, not material composition. Rayon absorbs fluid efficiently, which can promote moisture retention; risk is usage-dependent (replacement frequency) rather than product-specific, and applies equally to Kotex Natural and competitors.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Residual processing solvents in rayon (viscose)
Viscose rayon production uses sodium hydroxide and carbon disulfide, which are fully recovered in modern manufacturing. No measurable residues have been documented in finished tampon products; regulatory limits for vaginal contact materials are not exceeded.
Chlorine bleaching byproducts (dioxins, organochlorines)
Kotex Natural explicitly markets chlorine-free processing. Conventional tampon brands use elemental chlorine bleaching, which can generate trace dioxins; Kotex Natural avoids this step, eliminating this risk class for this product.
Pesticide residue
GOTS certification requires organic cultivation and prohibits synthetic pesticides. Residue testing is part of GOTS audit requirements, substantially reducing pesticide contamination risk compared to conventional cotton tampons.
Source, EPA ↗Fragrance allergens and irritants
Kotex Natural Super is unscented and does not use synthetic fragrance compounds known to trigger contact dermatitis or vulvar irritation. This eliminates a common irritation vector present in scented conventional tampons.
The full breakdown
What it's made of and why it matters
Kotex Natural Super uses rayon (viscose) derived from wood pulp and organic cotton, with a cardboard applicator. Rayon is a regenerated cellulose fiber produced via chemical processing, but the final material itself is chemically inert and does not retain processing solvents at levels of concern in finished products. Organic cotton avoids synthetic pesticide residues. Cardboard applicators eliminate the plastic leaching and microplastic concerns associated with plastic-tube designs.
The brand's record and disclosure
Kotex Natural line holds GOTS (Global Organic Textile Standard) certification for cotton components and Cradle to Cradle certification, indicating third-party oversight of chemical inputs and processing. The brand does not publicly disclose detailed chemical testing or PFAS policy, typical of the period-care sector. No significant safety recalls or regulatory warnings are on record for this product line. Certification reliance substitutes for transparent disclosure but provides independent verification.
How it compares in its category
This product ranks above conventional tampon lines (which use rayon blends without organic claims or third-party audit) due to GOTS certification and absence of synthetic fragrance or chlorine bleaching. It is comparable to other certified-organic tampon brands (Seventh Generation, Natracare) in material safety profile. Cost is typically 20-40% higher than conventional options, reflecting certification overhead rather than material superiority alone.
If you buy it
No special storage or handling is required beyond keeping the product dry and at room temperature. Replace every 4-8 hours to reduce bacterial overgrowth risk (standard across all tampon types). Do not reuse applicators. Discontinue use immediately if irritation, unusual odor, or allergic reactions occur; rayon and cotton are hypoallergenic but individual sensitivity varies. Cardboard applicators are compostable; dispose of the tampon body in waste (not flushed) despite marketing claims of biodegradability.
