Tranquility Select Underpad

Poor

Wait for brand to reveal waterproof coating composition before purchasing.

Verdict: SkipCellulose core is safe; waterproof backing composition undisclosed raises concern. Use if brand clarifies polymer coating, otherwise consider alternatives with transparent formulations.

These underpads rely on waterproof polymer backing to prevent leaks, but the exact coating remains undisclosed. Without transparency or testing, PFAS risk cannot be eliminated.

What’s concerning

♾️

Waterproof / stain-resistant treatment

Water-repellent treatments have historically contained PFAS chemicals.

65/ 100
♾️

Category baseline

PFAS exposure happens more often with clothing products.

75/ 100
♾️

No PFAS disclosure

The company has not publicly discussed PFAS in this product.

85/ 100
🍳

Waterproof polymer coating composition (unspecified)

Backing material and any water-repellent treatments are not disclosed. Risk depends on polymer type and additives; PFAS, phthalates, or other leachables cannot be ruled out without transparency.

Microplastics

Repeated wetting, friction, and flexing can cause synthetic polymer backing to fragment over months of use. Fragments potentially contact skin or enter washwater; impact unclear.

Off-gassing or odor from synthetic backing

New underpads may emit volatile organic compounds (VOCs) from polymer or adhesive curing, especially if stored in warm conditions. Airing before first use can reduce this.

70/ 100

What’s reassuring

Skin contact and irritant potential

No established reports of dermatitis from Tranquility Select specifically. Cellulose core is inert; risk would arise only if backing additives leach, which is undocumented.

Formaldehyde / VOCs

No public evidence that Tranquility uses formaldehyde-releasing adhesives in this product. Cellulose-based products sometimes employ urea-formaldehyde binders, but none reported here.

The full breakdown

What it's made of and why it matters

Tranquility Select Underpad uses a cellulose absorbent core (wood pulp-based, generally safe) with a waterproof polymer backing of unspecified composition. The backing is the critical unknown: it could be polyethylene, polypropylene, or a synthetic material treated with water-repellent coatings. Without disclosure, you cannot assess whether the backing contains PFAS, plasticizers, or other leachables that could contact skin during extended wear.

The brand's record and disclosure

Tranquility (SCA/Essity-owned) does not publicly disclose waterproof backing chemistry on product labels or websites. The brand has not published safety certifications (e.g., Oeko-Tex, GOTS) or composition transparency reports for this product. No major safety recalls or controversies are established in public records, but silence on formulation is a red flag for a product worn against sensitive skin for hours daily.

How it compares in its category

Period pads and underpads in this tier typically use similar cellulose-plus-polymer designs. Competitors like Kotex and Always also do not routinely disclose waterproof coating details, making this category-wide transparency problem rather than brand-specific. Brands offering certified organic or PFAS-free claims (e.g., some indie or EU-marketed products) are rare but exist; Tranquility Select does not market such positioning.

If you buy it

Store in a cool, dry place away from direct heat or sunlight, as polymers can degrade and release volatile compounds over time. Change underpads regularly; do not reuse if they show adhesive breakdown, discoloration, or odor (signs of material degradation). If you experience skin irritation, rash, or unusual odor during use, discontinue and contact the brand or dermatologist. Request the brand's material safety data sheet (MSDS) or waterproof coating specification before large purchases if skin sensitivity is a concern.
