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

Where these two actually differ

• We flag Microplastic shedding from waterproof backing, PTFE (Teflon) fume risk from waterproof coating, Skin sensitization from undisclosed adhesives or coatings and Formaldehyde-releasing resins in nonwoven bonding on the Always 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 Always.
• The Always is nonwoven cellulose/polyester blend with waterproof backing coating (unspecified) 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 Always grade, at 45% confidence against 78%, because it discloses less.
