What’s concerning
Category baseline
PFAS exposure happens more often with clothing products.
No PFAS disclosure
The company has not publicly discussed PFAS in this product.
Chlorine residues (dioxins) from bleaching
Rayon and cotton tampons may be bleached with chlorine compounds; conventional manufacturers (including Kotex) do not disclose bleaching methods. Dioxin residues, if present, occur in trace amounts not associated with acute toxicity in published literature, but organic/chlorine-free brands offer elimination of this uncertainty.
Pesticide residue
Cotton cover is not certified organic; residues of synthetic pesticides used in conventional cotton farming may persist. Exposure during vaginal insertion is minimal and diluted by mucous membranes, but individuals with chemical sensitivities or those seeking precaution may prefer organic-certified alternatives.
Source: EPA ↗Toxic shock syndrome (TSS) risk
TSS is a rare but serious bacterial infection associated with all tampon use, not specific to Kotex or material type. Risk is minimized by changing tampons every 4-8 hours and alternating with pads. This is a product-category hazard, not a manufacturing defect.
What’s reassuring
Safe base material
Made from ceramic, mineral, or natural fiber with no PFAS risk.
Formaldehyde / VOCs
Unscented U by Kotex Click is not marketed with antimicrobial or preservative additives typical of scented products. No evidence of formaldehyde releasers in this specific product formulation exists in public records.
Source: ATSDR ↗Plastic applicator off-gassing or leaching
Polypropylene applicators do not release BPA, phthalates, or volatile organic compounds under normal vaginal conditions (brief contact, body temperature). Applicator materials are inert and non-absorbent.
The full breakdown
What it's made of and why it matters
U by Kotex Click tampons use a rayon/viscose core (common in most commercial tampons for absorbency), a cotton cover, and a plastic applicator. Rayon and cotton do not leach toxic metals or endocrine disruptors under normal use conditions. The plastic applicator is typically polypropylene or similar thermoplastic, which does not degrade or leach during brief insertion and contact with body fluids at normal temperature.
The brand's record and disclosure
Kotex (Kimberly-Clark) has not published ingredient transparency reports or third-party certifications (e.g., organic, chlorine-free, or heavy-metal testing) for this product line. The brand does not publicly disclose PFAS testing or avoidance. No product recalls or regulatory violations specific to U by Kotex tampons are on record. Absence of disclosure is typical for conventional tampon manufacturers but limits independent verification.
How it compares in its category
U by Kotex Click sits in the mainstream, non-premium segment. It lacks certifications held by organic (GOTS) or chlorine-free brands, which some consumers prioritize. Material composition (rayon core, plastic applicator) is identical to most mass-market brands. Unscented formulation avoids fragrance additives that can trigger irritation in sensitive users, a practical advantage over scented variants.
If you buy it
Store in a cool, dry place away from moisture and direct heat; plastic applicators do not require special handling. Replace the product every 4-8 hours depending on flow to reduce toxic shock syndrome risk, regardless of brand. If you experience irritation, itching, or allergic reaction, switch to a hypoallergenic or organic brand to rule out cotton pesticides or processing residues. No maintenance or reuse applies to disposable tampons.
