Tranquility Select Ultra Underpad 36" X 36"

Poor

Waterproof coating materials not disclosed; skip until clarified.

Verdict: SkipCellulose core is safe; waterproof coating composition unknown and undisclosed by Tranquility, creating uncertainty around PFAS and other polymer hazards. Buy only if manufacturer confirms PFAS-free coating.

This underpad features cellulose with plastic backing and waterproof coating. The manufacturer hasn't made PFAS claims or documented coating materials publicly.

What’s concerning

♾️

Waterproof / stain-resistant treatment

Water-repellent treatments have historically contained PFAS chemicals.

Category baseline

PFAS exposure happens more often with clothing products.

♾️

No PFAS disclosure

The company has not publicly discussed PFAS in this product.

85/ 100
🍳

Waterproof coating composition (polymer/coating hazard)

The plastic backing likely uses synthetic polymers (polyurethane, polyethylene, or acrylics) as a base, possibly with fluorinated or non-fluorinated repellents. Tranquility's silence means PFAS presence cannot be ruled out. Non-PFAS alternatives (silicones, waxes) exist but are unconfirmed here.

70/ 100
🫧

Coating degradation and microplastic/leachate release

Over time, plastic coatings can crack, peel, or fragment, especially with repeated use, heat exposure, or mechanical stress. Degradation may release polymer particles or residual monomers. Risk is low for intact pads in normal use but increases with age or damage.

70/ 100
⚠️

Incineration or disposal byproducts (if burned improperly)

If PFAS-containing coatings are incinerated at low temperatures or burned in home fires, they may release hazardous fumes. Proper disposal (municipal waste or specialized incontinence-product take-back) minimizes this risk. Landfill disposal is safe.

70/ 100

What’s reassuring

Skin contact irritation from coating or adhesives

No reported widespread adverse reactions to Tranquility underpads are on record. Cellulose core is hypoallergenic. Any irritation would more likely stem from prolonged moisture contact than chemical composition, but individual sensitivities to plastic polymers are possible.

95/ 100

Cellulose core quality and mold/bacterial growth if stored wet

Cellulose itself is not prone to contamination if kept dry. Once saturated, the pad is designed for single use and disposal; extended moisture exposure could theoretically support mold, but this is outside normal use. No documented issues reported.

95/ 100

The full breakdown

What it's made of and why it matters

This underpad uses a cellulose core (wood pulp), which is inherently non-toxic and biodegradable. The concern centers on the plastic waterproof backing and coating layer applied to prevent liquid penetration. Tranquility has not publicly disclosed whether this coating contains PFAS (PFAS "forever chemicals"), which are persistent chemicals used to create water and oil repellency. Without ingredient transparency, consumers cannot assess whether synthetic polymers like polyurethane, acrylics, or fluorinated compounds are used.

The brand's record and disclosure

Tranquility (owned by Essity) does not maintain publicly available detailed material composition or PFAS declarations for this product line. The brand has not published independent certifications (e.g., OEKO-TEX, Cradle to Cradle, or PFAS-free statements) that would verify coating safety. This silence on waterproof treatment chemistry is typical of the incontinence-care industry, but it leaves a significant gap for consumers seeking certainty about exposure to synthetic chemicals.

How it compares in its category

Most disposable underpads (Attends, Depend, store brands) use similarly undisclosed waterproof coatings and face the same transparency gap. A small number of premium brands now market PFAS-free or certified-safe backing, though verification is limited. Reusable fabric underpads with washable polyurethane or sealed organic cotton liners offer an alternative if you want explicit material control, though upfront cost is higher.

If you buy it

Store in a cool, dry place away from heat and direct sunlight, as UV and warmth can degrade plastic coatings over time and potentially increase leaching. Replace underpads if the waterproof backing shows cracks, peeling, or delamination, as this compromises both function and chemical containment. Do not cut or crush pads, as this may fragment the plastic layer. If using for extended periods (e.g., daily for mobility-limited individuals), monitor skin for irritation, though reactions are uncommon.
