Where these two actually differ
- We flag Fluorochemicals (PFAS) in waterproof backing, Skin irritation and contact dermatitis from topsheet and adhesives, Cellulose degradation and fiber shedding and Chlorine and bleaching residues in cellulose on the Poise and not on the Seventh Generation.
- We flag Fragrance allergen content on the Seventh Generation and not on the Poise.
- The Poise is Cellulose core with synthetic polymer topsheet and waterproof backing 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 Poise grade, at 45% confidence against 78%, 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 →
