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 Poise.
- We flag Fluorochemicals (PFAS) in waterproof backing, Skin irritation and contact dermatitis from topsheet and adhesives, Cellulose degradation and fiber shedding and Chlorine and bleaching residues in cellulose on the Poise and not on the OB.
- The OB is rayon/viscose, cotton, and gelling polymers where the Poise is Cellulose core with synthetic polymer topsheet and waterproof backing, 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 Poise grade, at 45% confidence against 78%, because it discloses less.
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 →
