Where these two actually differ
- We flag Waterproof coating leachates (unknown chemistry) and Bacterial growth in core material on the Tena and not on the Eco By Naty.
- We flag Heavy metals in cellulose or plant-derived materials on the Eco By Naty and not on the Tena.
- The Tena is cellulose/polymer core with waterproof backing layer (type unspecified) where the Eco By Naty is Bamboo-derived viscose, cotton, plant-based absorbent core, which is most of the difference in these two grades.
- The gap is 45 points, wide enough that this is not a close call, and the Eco By Naty is the one to buy.
- We are less certain about the Tena 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 →
