Where these two actually differ
- We flag Bleach residues and processing chemicals in cellulose, Azo dyes or colorants in printed or top-sheet materials and Skin irritation or allergic sensitization from adhesives or synthetic fibers on the Nana and not on the Seventh Generation.
- We flag Fragrance allergen content on the Seventh Generation and not on the Nana.
- The Nana is cellulose, cotton blend, absorbent core where the Seventh Generation is organic cotton, wood pulp, 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, 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 →
