Pampers Swaddlers Ultra Diapers
High risk; skip until Pampers discloses waterproof layer composition.
These diapers use a waterproof back layer to prevent leaks, historically reliant on PFAS-based water-repellent coating treatments. Pampers makes no public disclosure of materials or PFAS status.

What Pampers Swaddlers Ultra Diapers is made of, ingredients and materials
Pampers Swaddlers Overnights use a multi-layer construction, an absorbent core of cellulose, superabsorbent polymer (SAP, typically sodium polyacrylate), and synthetic fibers; a waterproof back sheet of unspecified composition (likely plastic film); and topsheet and fastening materials. The waterproof layer is the critical unknown because it may contain PFAS compounds used to repel moisture, which do not degrade in the environment or body. Cellulose and SAP themselves are not acutely hazardous at intended use.
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.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
PFAS
Waterproof layer composition is undisclosed by Pampers. Industry data shows PFAS commonly used in diaper waterproof films; Pampers has not publicly committed to or ruled out PFAS. Exposure is dermal and prolonged contact with skin, particularly in infants whose toxicology is still developing.
Source, ATSDR ↗Skin irritation from fragrance or topsheet materials
Pampers Swaddlers Overnights are fragrance-free in many markets but contain synthetic topsheet fibers and adhesives. Sensitive infants or those with existing dermatitis may react to non-fragrance components; this is a recognized risk across the diaper category, not specific to Pampers, but incidence varies by individual.
Diaper rash bacteria or fungal growth
Risk is behavioral and environmental, not chemical. Diapers that remain wet or soiled create conditions for maceration and secondary infections; this applies to all diapers. Prevention depends on frequent changes and skin drying, not diaper brand or material formulation.
What’s reassuring
Superabsorbent polymer (SAP) exposure
Sodium polyacrylate SAP is used in most commercial diapers and has been evaluated by regulators as low concern when contained within the diaper structure. No published evidence of systemic toxicity from intact diaper use; however, if the core is breached and SAP contacts skin or is ingested, contact poison control. This is a manufacturing defect risk, not an inherent chemical hazard.
Chemical off-gassing or leachates from adhesives and fasteners
Pampers diapers have not been recalled for adhesive toxicity or volatile organic compound (VOC) emissions. Adhesives and elastic materials are generally stable at body temperature and humidity. No published independent testing of off-gas profiles is available for this specific product.
How is this PFAS grade calculated?
The brand's record and disclosure
Pampers (Procter & Gamble) has not publicly disclosed the specific chemical composition of diaper waterproof layers, despite industry-wide scrutiny of PFAS use in absorbent products. The brand has faced no major recalls for chemical contamination of this product line, but the silence on waterproof layer ingredients is a red flag for transparency. P&G maintains general safety claims but has not committed to PFAS-free formulations or third-party testing disclosure for diapers.
How it compares in its category
Pampers Swaddlers Overnights are a premium mainstream diaper; the PFAS concern applies broadly to conventional waterproof diapers, not uniquely to Pampers. Brands such as Mama Bear, Seventh Generation, and Pampers Swaddlers (non-overnight) have made incremental disclosure improvements, though none have definitively ruled out all PFAS. Cloth diaper systems and some eco-brands attempt to avoid synthetic waterproof barriers altogether, though their absorbency and overnight performance differ.
If you buy it
Use as directed (change every 2-4 hours or when soiled) to minimize skin contact duration. Store in a cool, dry place away from direct heat or sunlight; there is no evidence heat degrades the diaper in normal home conditions, but prolonged exposure to moisture can degrade adhesives. Discontinue if your infant shows signs of irritation (rash, redness) and switch to a hypoallergenic or fragrance-free variant. Dispose in household waste; do not flush or burn.
