Seventh Generation Chlorine-Free Maxi Pads
Lower PFAS concern; typical period-pad materials rarely require water/stain barriers where PFAS commonly hide.
Seventh Generation's chlorine-free pads use standard cellulose and cotton fibers with no disclosed water-repellent or stain-resistant coatings, the typical vectors for PFAS in period products. The brand makes no PFAS claims either way.

The full breakdown
What it's made of and why it matters
Seventh Generation Maxi Pads use cellulose (wood pulp), cotton, and SAP (super-absorbent polymer) with chlorine-free bleaching. Avoiding chlorine in bleach eliminates the risk of dioxin formation, a legacy concern in conventional pad manufacturing. The cotton and cellulose are absorbent but inert when worn; SAP is a synthetic polymer (typically sodium polyacrylate) that is not absorbed through skin and has no established dermal toxicity at the concentrations used in pads.
The brand's record and disclosure
Seventh Generation markets itself on transparency and has published ingredient lists and sustainability commitments, though full third-party testing data for this specific product line is not publicly available. The brand holds no major safety recalls specific to this pad line and maintains certifications in some green/ethical product spaces. However, the brand does not publicly disclose PFAS testing or make explicit PFAS-free claims for this product, which is typical across the period-pad category.
How it compares in its category
Chlorine-free pads are now standard in mainstream brands (including Kotex, Always, and store brands); Seventh Generation is not unique but reflects industry baseline rather than leading innovation. Compared to organic cotton-only pads (e.g., Cora, Lola), this product uses synthetic SAP, making it cheaper and more absorbent but less minimalist. Compared to conventional bleached pads, the chlorine-free choice reduces one historical contaminant class but does not eliminate all chemical processing.
If you buy it
Store pads in a cool, dry place away from direct sunlight to prevent SAP degradation and odor. Replace every 4-8 hours during use to minimize bacterial growth and irritation; do not leave worn pads in underwear longer than necessary. If you experience persistent irritation, rash, or odor, switch to an alternative material (e.g., organic cotton) to isolate whether the product or your individual sensitivity is the cause. Dispose of used pads in household waste, not toilets, to avoid plumbing and environmental impact.
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.”
Formaldehyde resins in cellulose/cotton processing
Chlorine-free bleaching does not eliminate use of formaldehyde-releasing resins in some pulp processing; however, no recalls or complaints specific to Seventh Generation pads for formaldehyde odor or irritation are on public record. Industry standard for cellulose pads.
Azo dyes or synthetic dyes in outer layer/packaging print
Seventh Generation pads use minimal printing and do not prominently use colored dyes on the absorbent surface. No established reports of azo-dye contamination in this product line.
Talc or talc-like mineral contamination
Seventh Generation pads are not marketed as talc-dusted and contain no known talc. The brand does not use talc as a release agent or absorbent modifier in this product.
Bacterial growth and odor from SAP or moisture retention
SAP in all period pads (including this one) retains moisture and can support bacterial and yeast growth if pads are worn for extended periods or stored damp. This is a use-practice risk, not a product defect, and affects all conventional pad brands equally.
Skin irritation from chlorine-free bleach byproducts or residual chemicals
Chlorine-free bleaching (e.g., oxygen or hydrogen peroxide-based) leaves fewer known irritant residues than chlorine bleach, and no pattern of irritation complaints linked to Seventh Generation's chlorine-free pads is documented. Individual sensitivity varies.
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.
