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 Seventh Generation.
- We flag Fragrance allergen content on the Seventh Generation and not on the OB.
- The OB is rayon/viscose, cotton, and gelling polymers 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 →
