Aunt Flow Tampon Cartridge
Lower PFAS concern, standard tampon materials lack typical fluorochemical triggers, but brand silent on sourcing.
Tampons historically have not required PFAS coatings; cotton and rayon cores are baseline textiles without obvious water-repellent coating or stain-resistance treatments that would warrant fluorochemicals. Aunt Flow does not publicly disclose PFAS sourcing or testing, which is typical industry-wide silence rather than a red flag.

Why this grade

No public statement about PFAS in this product.
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
Aunt Flow tampons use a cotton/rayon absorbent core with a polyethylene plastic applicator. Cotton and rayon are cellulose fibers with minimal chemical reactivity in typical use; polyethylene applicators do not leach endocrine disruptors like BPA or phthalates under normal conditions. The material combination is standard across the tampon category and lacks known chemical hazards associated with heated or prolonged contact with acidic/basic environments.
The brand's record and disclosure
Aunt Wendy (Aunt Flow) does not publicly disclose bleaching methods, pesticide sourcing, or supply chain certifications on readily available materials. The brand has not faced documented recalls or safety violations. No third-party testing results or organic/chlorine-free certifications are prominently advertised, limiting independent verification of material purity relative to competitors offering certified alternatives.
How it compares in its category
Tampons with plastic applicators occupy the mid-market segment; Aunt Flow sits in standard performance territory without premium certifications (e.g., GOTS organic, chlorine-free elemental chlorine-free ECF). Competing brands offering certified organic cotton or applicator-free options provide additional assurance; Aunt Flow's position reflects typical material safety but less transparency than leading certified alternatives.
If you buy it
Use applicators as directed; plastic applicators are not designed for reuse and should be disposed after single use. Store in a cool, dry place away from direct heat or UV exposure (applicator brittleness over time is cosmetic, not hazardous). Change tampons every 4-8 hours per standard gynecological guidance to minimize bacterial overgrowth risk. No special precautions beyond typical tampon hygiene are necessary based on material composition.
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.”
Bleaching residues and dioxins
Cotton and rayon are typically bleached; if Aunt Flow uses chlorine-based bleaching, trace dioxin residues are possible but remain within regulatory limits for menstrual products in most jurisdictions. Brand silence on bleaching method prevents confirmation of low-residue alternatives.
Pesticide residues in conventional cotton
Conventional cotton is heavily pesticide-treated; Aunt Flow does not specify organic sourcing, meaning residues may be present at levels compliant with food/cosmetic standards but higher than organic alternatives. Direct vaginal absorption is minimal but cumulative exposure over product lifetime merits consideration.
Polyethylene applicator degradation
Polyethylene applicators are chemically stable under normal body conditions and do not shed microplastics at detectable levels during typical single-use exposure. No documented cases of applicator fragmentation or leaching in clinical use.
Bacterial contamination from manufacturing
Tampons are manufactured under controlled hygiene standards in most markets; Aunt Flow products have no documented recalls for bacterial contamination. Risk is consistent with the broader tampon category and not elevated by material choice.
Fragrance or additive allergens
Aunt Flow tampons are described as unscented core products; scented variants (if offered) may carry fragrance allergen risk typical of cosmetic-grade additives, but standard variant poses minimal contact allergen 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.
