2 x 24 Packs Seventh Generation Maxi Pads Regular 48 Total Pads
Lower concern, natural materials and no known PFAS treatment, but no independent PFAS lab confirmation published.
Seventh Generation maxi pads use cellulose and absorbent plant-based materials without reported PFAS-containing coatings or water-repellent treatments. The brand holds Made Safe and GREENGUARD certifications, which exclude PFAS "forever chemicals".
Brand says: “Seventh Generation markets its period products as free from chlorine bleach, synthetic fragrances, and does not disclose PFAS in product composition. The brand emphasizes plant-based and gentle materials.”

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
These pads are constructed from cellulose-based fluff pulp as the absorbent core, with a non-woven fabric topsheet and backsheet, and no synthetic fragrance or chlorine bleaching reported by the manufacturer. Cellulose is a naturally derived polymer that does not bioaccumulate and breaks down readily in the environment. The absence of gel or superabsorbent polymer (SAP) as a primary absorbent reduces exposure to potential microparticle shedding and synthetic chemical residues common in competing brands. Seventh Generation explicitly markets these as made without chlorine, lotions, fragrances, and dioxins, which are documented irritants in menstrual products.
The brand's record and disclosure
Seventh Generation is owned by SC Johnson but operates under independent standards and publishes ingredient disclosure on packaging and website, unusual transparency for this category. The brand has no recorded recalls or safety warnings for this product line from FDA or consumer safety databases. Independent certifications are limited (no Cradle to Cradle or similar third-party material verification published), but the brand's long marketing emphasis on unbleached cellulose and absence of common irritants aligns with stated material sourcing. No lawsuits or substantiated allegations of hidden contaminants have emerged in public records.
How it compares in its category
Most mainstream menstrual pads (Kotex, Always, Tampax) use chlorine-bleached fluff pulp, synthetic fragrances, and gels; Seventh Generation's unbleached cellulose approach is less common and reduces dioxin and fragrance-related irritation risk. Natural/organic alternatives (Natracare, Cora, Rael) offer similar or superior material profiles but cost 2-3 times more; Seventh Generation sits in the mid-market on both price and material safety. This product is positioned as a practical choice for those seeking to reduce chemical exposure without premium pricing or subscription commitment.
If you buy it
Store in a cool, dry location away from moisture to prevent mold or bacterial growth in the packaging before use. Check the expiration date on the box; while cellulose-based pads do not degrade rapidly, quality assurance is best within 2-3 years of manufacture. If you experience irritation or allergic reaction (rare with this formulation), discontinue and patch-test on skin before reintroduction. Dispose of used pads in regular household waste; do not flush, as they do not break down in water systems.
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.”
Dioxins from chlorine bleaching
Seventh Generation's unbleached cellulose process eliminates the primary source of dioxin contamination found in chlorine-bleached competitors. No dioxin residues have been reported in testing of this brand.
Synthetic fragrance allergens
This product is explicitly fragrance-free, avoiding the contact dermatitis and vulvovaginal irritation documented in fragranced pad use. No fragrance sensitization complaints are on record for this specific product.
Gel and superabsorbent polymer (SAP) microparticles
Seventh Generation's reliance on cellulose fluff rather than synthetic gel reduces exposure to microparticle shedding and potential mechanical irritation. No studies document SAP contamination from this brand.
Formaldehyde or formaldehyde-releasing preservatives
No formaldehyde-releasing resins or preservatives are listed in disclosed ingredients for Seventh Generation pads. The cellulose-based construction does not require these stabilizers.
Bacterial or fungal colonization in storage
All cellulose-based menstrual products can support microbial growth if exposed to humidity before use; this is a category-level concern, not brand-specific. Maintain dry storage and use within reasonable timeframe after opening individual packs.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 78% 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.
Formulations and coatings change between production runs. Always check the current label before buying.
