What Aunt Flow Organic Cotton Cardboard Tampons is made of, ingredients and materials
Aunt Flow tampons use certified organic cotton for the absorbent core, which avoids synthetic pesticide residues and synthetic fibers. The cardboard applicator is a low-concern alternative to plastic (which can contain phthalates or BPA) and does not require protective coatings that might leach. Cardboard and organic cotton are both biodegradable and pose minimal chemical exposure during typical use. No manufacturing process for organic cotton tampons typically introduces dioxins or furans at consumer-relevant levels.
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.
Cardboard applicator splinter or surface contamination
Cardboard applicators can splinter or shed fibers if dropped or mishandled, but this is a mechanical rather than chemical hazard. No user injury pattern is documented for Aunt Flow brand specifically.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Pesticide residue
Organic cotton certification eliminates synthetic pesticide exposure. Aunt Flow explicitly markets organic status, so residue risk is lower than conventional tampons.
Source, EPA ↗Dioxins and furans (bleaching byproducts)
Modern tampon manufacturing, including Aunt Flow's suppliers, typically uses elemental chlorine-free or totally chlorine-free bleaching. No recall or testing data implicates this product.
Synthetic fragrance or allergens
Aunt Flow markets unscented tampons as standard; no fragrance additives or dyes are documented. No allergen incidents on record.
Heavy metals
Food-grade cardboard used in tampons is regulated for heavy metals and inks. No contamination incidents are on record for this brand or material class.

The brand's record and disclosure
Aunt Flow is a mission-driven brand focused on period equity and material transparency; they advertise organic certification and have not faced recalls or contamination scandals on record. The brand does not make explicit PFAS claims but their choice of organic cotton and cardboard inherently avoids water-resistant treatments that would require PFAS or other fluorochemicals. No major certifications beyond organic claim are documented for this specific product line. Public disclosure of supply-chain testing or third-party audit results is limited.
How it compares in its category
Cardboard applicators with organic cotton represent a lower-concern option compared to plastic applicators (which may contain phthalates, BPA, or flame retardants) or rayon-blend tampons (which can involve higher dioxin risk in bleaching). Conventional (non-organic) cotton tampons may carry pesticide residues but pose similar acute chemical hazards during use. Aunt Flow's positioning aligns with other organic, applicator-focused brands like Cora and Seventh Generation; this product is mid-market in price and material transparency.
If you buy it
Store in a cool, dry place to prevent cardboard softening or mold; no special handling is required. Cardboard applicators are not prone to cracking or leaching under normal body temperature or humidity. Discard applicator in household trash after use (cardboard is not flushable despite being biodegradable). Use until expiration date; no shelf-life stability concerns are documented for this product.
