Modess Basics Regular Maxi Pads with Wings

Good

Skip pending PFAS disclosure from manufacturer.

Verdict · SkipPFAS disclosure gap and moderate concern on dioxane/formaldehyde require brand clarity; material composition itself poses lower concern if manufacturing standards are met.

Modess does not publicly disclose PFAS use or testing for this product. Menstrual pads often receive water-resistant treatments of unknown chemistry. Request PFAS information from the brand before purchase.

What Modess Basics Regular Maxi Pads with Wings is made of, ingredients and materials

Modess Basics uses rayon (the absorbent layer), polypropylene (structure and wings), and polyethylene (backing/core). Rayon is a cellulose fiber that does not inherently leach chemicals, but its production involves chemical processing; polypropylene is stable and low-leach at body temperature. The material combination itself is standard across the category. What matters is whether bleaching agents, residual solvents, or finishing chemicals remain in the final product after manufacturing.

No PFAS disclosure

No public statement from the brand about PFAS in this product.

85/ 100
⚠️

1,4-dioxane (residual solvent from rayon production)

Rayon manufacturing commonly involves ethoxylation processes that can leave trace 1,4-dioxane in finished fibers. Modess does not disclose testing or limits; no public recall or advisory exists for this brand, but the hazard class is recognized in the FDA guidance for menstrual products.

70/ 100
💨

Formaldehyde / VOCs

Conventional pads often use formaldehyde-based resins in fabric finishing or as antimicrobial agents. Modess Basics does not specify whether such agents are used or how thoroughly they are rinsed. No formaldehyde recall or test data is on record for this product.

⚠️

Chlorine residues (if bleached rayon)

Rayon fibers are typically bleached during production; if Modess uses chlorine bleaching, residual chlorine compounds or organochlorines could remain. The brand does not specify bleaching method (chlorine vs. oxygen-based). Chlorine-free claims are absent from product labeling.

70/ 100
⚠️

Allergens or irritants from adhesives and synthetic polymers

Polypropylene wing adhesives and polyethylene backing materials are generally inert at body temperature, but individual sensitivity to synthetic materials or adhesive residues has been documented anecdotally in period-product users. No brand-specific adverse-event database entry exists, but the category carries low but nonzero irritation risk.

45/ 100

What’s reassuring

✅

Microplastic shedding from synthetic fibers (polypropylene, polyethylene)

No peer-reviewed study or manufacturer data confirms microplastic release from conventional menstrual pads during use. Concern is theoretical; the product is not heated or abraded in use in ways known to fragment synthetic polymers into the body.

95/ 100

The full breakdown

The brand's record and disclosure

Modess (Procter & Gamble brand) does not publicly disclose detailed ingredient lists, processing chemicals, or third-party safety certifications (e.g., Cradle to Cradle, FDA clearance for medical claims). The brand has not issued voluntary PFAS testing results or commitment statements on 1,4-dioxane or formaldehyde residues in period products, despite these being documented contaminants in the category. This silence is not equivalent to absence of risk; it reflects a gap in transparency rather than confirmed safety.

How it compares in its category

Modess Basics is a conventional, mass-market pad with no organic, chlorine-free, or certified safety positioning. Competitors such as Seventh Generation, Natracare, and Cora explicitly market chlorine-free, hypoallergenic, or organic credentials and publish ingredient transparency. Modess Basics occupies the budget-price tier where manufacturing transparency is typically lower. Performance and absorbency are generally comparable across brands; differentiation hinges on material sourcing and processing chemical disclosure.

If you buy it

Store in a cool, dry place away from direct heat or sunlight to avoid potential off-gassing of residual solvents. Replace pads every 4-8 hours depending on flow; do not leave in place beyond a full day to reduce bacterial overgrowth risk. If you experience irritation, rash, or unusual odor, discontinue and switch to a brand with certified hypoallergenic or organic positioning. Request or seek out independent lab results if you have sensitivities; do not assume unlabeled products are free of formaldehyde or dioxane residues.
