Carefree Ultra Thin Pads With Wings vs O.b Pro Comfort Super Plus 16 pad: which is safer?

Where these two actually differ

• We flag Water-resistant topsheet coating (unspecified chemistry), Fragrance allergens (scented variants) and Adhesive contact irritation on the Carefree Acti-Fresh and not on the OB.
• We flag Microplastic shedding or degradation, Irritation or allergic sensitization from adhesive or synthetic fibers and Bacterial growth or contamination from prolonged moisture on the OB and not on the Carefree Acti-Fresh.
• The Carefree Acti-Fresh is nonwoven synthetic layers with unspecified water-resistant topsheet coating where the OB is rayon/viscose, cotton, and gelling polymers, 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 OB is the one to buy.
• We are less certain about the Carefree Acti-Fresh grade, at 45% confidence against 78%, because it discloses less.
