Where these two actually differ

  • We flag Waterproof coating composition (undisclosed) and Skin irritants and sensitizers in coatings or adhesives on the Libresse and not on the Seventh Generation.
  • We flag Fragrance allergen content on the Seventh Generation and not on the Libresse.
  • The Libresse is cellulose/cotton core with unspecified waterproof/fluid-barrier coatings where the Seventh Generation is organic cotton, wood pulp, which is most of the difference in these two grades.
  • The gap is 75 points, wide enough that this is not a close call, and the Seventh Generation is the one to buy.
  • We are less certain about the Libresse grade, at 35% 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 →
