What Seventh Generation Maxi Pads - Overnight is made of, ingredients and materials
Seventh Generation Overnight pads use cotton, wood pulp, and plant-based coatings rather than petroleum-derived synthetics common in conventional pads. Cotton and wood pulp are absorbent natural fibers with no known leaching hazards under normal use. Plant-based coatings replace conventional plasticizers and adhesives, reducing exposure to synthetic chemical residues during prolonged intimate contact.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
Allergen or irritant from plant-based coating
Plant-based adhesives and coatings are generally lower-risk than synthetic alternatives, but individual skin sensitivity to plant compounds (e.g., tree resins, gums) is documented in some users. No widespread recalls recorded for Seventh Generation pads on this basis.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Third-party PFAS-free verification
A third party reports verifying this product as PFAS-free.
Bleach residues in wood pulp
Wood pulp is commonly chlorine-bleached in conventional pads; Seventh Generation does not disclose bleaching method in available public materials. No contamination recalls or testing results are on record for this product.
Microplastic or microfiber shedding from degradation
Cotton and wood pulp are biodegradable and do not shed microplastics. Synthetic backings used in some pads are the primary source of microplastic concern; this product uses plant-based materials instead.
Talc or silica contamination
Menstrual pads do not typically contain talc. Silica or diatomaceous earth are occasionally used in superabsorbent polymers; none is disclosed for this product, and no contamination is on record.
Fragrance or fragrance allergens
Seventh Generation markets this product as fragrance-free. No added fragrance compounds or fragrance allergens are disclosed; however, plant-based materials may carry residual botanical scents.
How is this PFAS grade calculated?
The brand's record and disclosure
Seventh Generation publishes ingredient disclosure and holds third-party certification for PFAS-free status. The brand has no recorded recalls for this product line related to chemical contamination. The company markets transparency on menstrual-product chemistry, though independent testing by third parties (e.g., Women's Voices for the Earth) is limited in the public domain for this specific SKU.
How it compares in its category
Most conventional overnight pads use synthetic superabsorbent polymers (SAP), plastic backing, and chlorine bleaching. This product avoids those in favor of natural fibers and plant-derived binders. Compared to conventional pads, it carries lower reported concern for synthetic chemical exposure; compared to other organic-certified brands (e.g., Lola, Cora), positioning is similar in material philosophy and price tier.
If you buy it
Use as directed; no special storage or activation required. Replace every 4-8 hours depending on flow; overnight pads are designed for extended wear but not beyond manufacturer guidance. Store in a cool, dry place; no heat treatment or washing is standard. Discontinue if skin irritation develops; contact dermatitis is uncommon but possible with any pad in sensitive individuals.
