Where these two actually differ

  • We flag Fragrance allergen content on the Seventh Generation and not on the Seventh Generation.
  • We flag Chlorine residues from bleaching on the Seventh Generation and not on the Seventh Generation.
  • The Seventh Generation is organic cotton, wood pulp where the Seventh Generation is Organic cotton, wood pulp, adhesives, which is most of the difference in these two grades.
  • The gap is 30 points, wide enough that this is not a close call, and the Seventh Generation 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 →
