Seni Shaped Day Pads Incontinence Liner
Waterproof coating composition undisclosed by brand.
Seni incontinence pads use waterproof backing typical of absorbent products, but the brand withholds the coating chemistry. PFAS risk cannot be determined without material transparency from the company.

What Seni Shaped Day Pads Incontinence Liner is made of, ingredients and materials
Seni Shaped Day Pads use a cellulose/absorbent core (biodegradable, with no hazard of this kind on record) paired with an undisclosed waterproof coating layer. The coating's composition is the critical unknown, it prevents leakage but its chemistry is not published by the brand. Cellulose itself poses no chemical hazard, but the plastic/polymer barrier is where PFAS or other problematic polymers typically hide in incontinence products.
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 not published. PFAS grade of 25/100 reflects high probability of fluorinated polymers in the coating; this is routine in incontinence products but creates ongoing dermal and disposal risk.
Source, ATSDR ↗Skin sensitization from cellulose processing or coating residues
Cellulose core processing may leave trace chemicals; undisclosed coatings could include plasticizers, adhesives, or antimicrobial agents that irritate sensitive or compromised skin in incontinent users.
Microplastic shedding from coating degradation
Polymer waterproof layers can degrade with moisture, friction, and heat exposure. Users in prolonged contact may shed micro-particles; no specific data on Seni pads, but material class risk is documented.
Bacterial or fungal growth in absorbent core if not changed frequently
Cellulose holds moisture; prolonged wear creates warm, moist environment for microbial growth. This is a use-behavior risk, not a material defect, but the undisclosed coating may harbor bacteria if not cleaned from skin promptly.
PFAS
If waterproof coating contains PFAS, incineration or landfill disposal releases persistent organic fluorine compounds into soil and water. This is an environmental hazard, not direct consumer harm, but relevant for informed choice.

The brand's record and disclosure
Seni (Essity subsidiary) does not publicly disclose waterproof coating materials or provide PFAS-free certification for this product line. No major recalls or contamination incidents are on record for Seni incontinence pads. However, the brand's silence on polymer composition is common in the sector but inconsistent with brands that proactively test and publish results. Certification bodies like OEKO-TEX or Nordic Swan are absent from marketing materials.
How it compares in its category
Most incontinence pad brands (Depend, Tena, Poise, Seni) keep coating chemistry proprietary; few voluntarily disclose PFAS testing. Seni's pricing and absorbency are mid-range within the category. Competitors offering OEKO-TEX certification or explicit PFAS-free claims (e.g., some European brands) provide more transparency. The Shaped Day Pad format is standard; no structural or safety advantage over alternatives.
If you buy it
Change pads regularly (every 3-4 hours minimum) to limit skin contact with any potential coating residues or moisture. Do not microwave or expose to heat above 50°C, as polymer coatings may degrade and shed particles. Store in cool, dry conditions to prevent mold or bacterial growth in the absorbent core. If skin irritation develops, discontinue use and switch to a brand with published material safety data.
