Where these two actually differ
- We flag Topsheet polymer/treatment composition unknown, Contact dermatitis and skin irritation (generic) and Moisture retention and bacterial/fungal growth on the Nana 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 Nana.
- The Nana is cellulose, absorbent core, likely aqueous or silicone topsheet treatment 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.
Both products run through the same public rubric: materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
