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

Where these two actually differ

• We flag Undisclosed water-resistant coating (likely PFAS or alternative fluorinated compounds), Skin irritation from undisclosed additives or residual chemicals, Microplastic or polymer shedding from backing layers and Allergic reaction to fragrance or adhesive (if present) on the Kotex 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 Kotex.
• The Kotex is bamboo viscose, cellulose core, polyethylene/polypropylene layers, unspecified water-resistant 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 Kotex grade, at 52% confidence against 78%, because it discloses less.
