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 Tampax.
- We flag Fragrance allergens (if scented variant) on the Tampax and not on the OB.
- The OB is rayon/viscose, cotton, and gelling polymers where the Tampax is Rayon/viscose core, cotton-blend outer, no known coating, which is most of the difference in these two grades.
- These two are level, close enough that price and fit should decide it rather than our grade.
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 →
