Where these two actually differ

  • We flag PFAS in waterproof backing, Adhesive or fragrance irritants and Coating degradation over time or with heat on the Kotex and not on the Natracare.
  • We flag Fragrance allergens (if scented variant) and Bacterial overgrowth from prolonged wear on the Natracare and not on the Kotex.
  • The gap is 75 points, wide enough that this is not a close call, and the Natracare is the one to buy.
  • We are less certain about the Kotex grade, at 35% confidence against 100%, because it discloses less.

Both products run through the same public rubric, which covers 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 →
