SCA Tena Serenity Heavy Pads
Skip until brand discloses waterproofing chemistry.
SCA Tena pads use waterproof backing to prevent leaks, likely treated with water-repellent chemicals. The brand does not disclose PFAS status or materials; waterproof incontinence pads frequently contain PFAS-based treatments.

The full breakdown
What it's made of and why it matters
Tena Serenity Heavy Pads use a cellulose absorbent core (wood pulp-based, standard for the category) layered with nonwoven polypropylene backing and a waterproof polymer layer to prevent leakage. The waterproof layer is the critical unknown: SCA has not publicly disclosed whether it contains PFAS compounds (PFAS "forever chemicals" used for water and oil repellency). Cellulose itself carries minimal toxicity risk, but the backing materials and adhesives warrant scrutiny given prolonged skin contact.
The brand's record and disclosure
SCA (Swedish Forest Products Company) does not appear to have published ingredient disclosures or PFAS statements for Tena products publicly available to consumers. No recalls or safety actions specific to Tena Serenity pads are on record with regulatory bodies (FDA, CPSC, or international equivalents). The brand silence on waterproofing chemistry is notable given industry-wide PFAS awareness since approximately 2015 and competitor disclosures from brands like Seventh Generation and Kotex.
How it compares in its category
Tena Serenity is a mainstream, economical option; absorbency and comfort ratings are typical for heavy-flow pads. Many competitors (notably Seventh Generation Free & Clear and some organic-certified brands) have begun voluntarily disclosing PFAS-free or natural fiber constructions; Tena has not matched this transparency trend. Category-wide, PFAS use in waterproof backing layers remains common but increasingly questioned by health advocates and retailers.
If you buy it
Store pads in a cool, dry place away from direct sunlight to prevent adhesive or polymer degradation. Discontinue use if you notice persistent rash, irritation, or odor that suggests chemical off-gassing or bacterial growth in the core. Consider rotating brands periodically or requesting SCA's waterproofing ingredient list directly; consumer demand for disclosure is an effective lever. If PFAS exposure is a personal concern (e.g., medical history), switching to certified organic or explicitly PFAS-disclosed alternatives reduces uncertainty.
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 layer
SCA has not disclosed the chemical composition of the waterproof polymer layer. PFAS compounds are commonly used in period-product waterproofing globally; direct skin contact over hours daily raises potential for absorption or leaching, though acute toxicity from a single pad is unlikely.
Nonwoven polypropylene degradation and microplastics
No reported issues of visible shedding or microplastic release from Tena Serenity pads in published literature or complaints databases. Standard polypropylene backing is structurally stable under normal use conditions, but prolonged moisture exposure or friction could theoretically degrade fibers over time; evidence specific to this product is absent.
Adhesive or coating volatiles (VOCs)
SCA does not publicly disclose adhesive formulations. Standard medical-grade pad adhesives are typically acrylate-based and low-VOC, but no third-party testing results for Tena Serenity are available to confirm this product's off-gassing profile.
Chlorine bleaching residues in cellulose core
Cellulose pulp in disposable pads is often chlorine-bleached; residual dioxins or organochlorine compounds are possible but typically present in trace amounts regulated by food-contact standards. SCA does not specify bleaching method or residue testing for Tena products.
Skin irritation from fragrance or other additives
Tena Serenity pads are marketed as fragrance-free, reducing allergen load compared to scented competitors. However, the nonwoven backing, adhesive, and core materials may contain undisclosed processing aids or antimicrobial additives that could trigger irritation in sensitive users; individual variation is high.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 45% 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.
