TENA Serenity Overnight Pads
Skip until brand discloses waterproof backing materials and PFAS status.
Overnight pads require waterproof backing, typically treated polymers that may contain PFAS. Tena/Essity provides no public disclosure of materials or PFAS testing.

The full breakdown
What it's made of and why it matters
TENA Serenity Overnight Pads use an absorbent core (typically wood pulp and super-absorbent polymer SAP) with a waterproof backing of unspecified synthetic polymer. The backing material is critical because it contacts skin for hours and may contain PFAS, plasticizers, or other polymeric additives. The absorbent core itself is generally low-risk, but the waterproof layer's composition directly affects leaching potential into skin or menstrual fluid.
The brand's record and disclosure
Serenity (owned by SCA/Essity, a major hygiene manufacturer) has not publicly disclosed the specific polymer type or chemical composition of the waterproof backing on this product. The brand has not issued statements regarding PFAS use in period-care products. Industry-wide, major pad manufacturers have begun voluntary PFAS disclosure under pressure, but Serenity's silence on this specific product remains a transparency gap.
How it compares in its category
Most overnight pads use similar polyethylene or polypropylene backings; Serenity is not an outlier in design. However, brands like Seventh Generation and Kotex have begun disclosing waterproof backing materials more explicitly. Premium organic alternatives (Cora, Rael) market PFAS-free claims, though independent verification is limited. Serenity's lack of transparency puts it in a middle tier where material safety is assumed rather than verified.
If you buy it
Change pads every 4-8 hours to minimize skin contact duration and reduce leaching risk from any coating additives. Store in a cool, dry place to avoid polymer degradation. If you experience unexplained skin irritation, sensitivity, or rashes, discontinue and note the timing; this may signal incompatibility with backing material or coatings. Request the brand to disclose waterproof backing materials in writing before repurchasing, as market pressure drives transparency.
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.”
PFAS in waterproof backing
Waterproof synthetic polymer backing composition is not disclosed by brand. PFAS is commonly used in menstrual product backings to enhance water repellency; absence of brand statement does not confirm absence of PFAS.
Plasticizer leaching (phthalates, adipates)
If the waterproof backing is a plasticized polymer (common in budget products), phthalates or other plasticizers may migrate to skin or menstrual fluid, especially during extended wear or in warm conditions.
Skin irritation from polymer coatings or additives
Menstrual pads with unspecified synthetic backings have been associated with contact dermatitis and skin irritation in consumer reports; causation often unclear but may involve coating additives, residual monomers, or PFAS.
Super-absorbent polymer (SAP) particle shedding
No specific safety issue is on record for TENA's absorbent core; SAP is industry standard and regulated. Microparticles are not expected under normal use.
Dioxin/furan contamination in bleached core
Chlorine-bleached wood pulp in pads has historically carried trace dioxin risk, but modern manufacturing controls and oxygen-bleaching have mitigated this; no specific alerts for TENA products are on record.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 35% 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.
