Wings Plus Heavy Absorbency Underpad vs PBE Tranquility Personal Care Pads: which is safer?

Where these two actually differ

• We flag Synthetic backing composition (unknown fluorine/PTFE risk), Microplastic shedding from synthetic core and degrading backing and Skin irritation and sensitization risk from unidentified materials on the BetterCare and not on the Tranquility.
• We flag Chlorine bleaching byproducts (dioxins) and Allergens in fragrance or additives on the Tranquility and not on the BetterCare.
• The BetterCare is synthetic fiber core with waterproof backing layer, composition unspecified where the Tranquility is Cellulose, rayon, cotton absorbent core (standard pad materials), which is most of the difference in these two grades.
• The gap is 45 points, wide enough that this is not a close call, and the Tranquility is the one to buy.
• We are less certain about the BetterCare grade, at 35% confidence against 72%, because it discloses less.
