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

Where these two actually differ

• 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 Playtex.
• We flag Undisclosed moisture-barrier coating (likely fluorochemical), Bleach residues in cotton/rayon core, Allergic sensitization to synthetic materials or dyes and Bacterial growth from moisture and occlusion on the Playtex and not on the OB.
• The OB is rayon/viscose, cotton, and gelling polymers where the Playtex is Cotton/rayon core, plastic backing with moisture-barrier coating, 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 Playtex grade, at 45% confidence against 78%, because it discloses less.
