Where these two actually differ

  • We flag Heavy metals in cellulose or plant-derived materials on the Eco By Naty and not on the Seni.
  • We flag Undisclosed waterproof coating polymers (including possible PFAS), Skin sensitization from cellulose processing or coating residues, Microplastic shedding from coating degradation and Bacterial or fungal growth in absorbent core if not changed frequently on the Seni and not on the Eco By Naty.
  • The Eco By Naty is Bamboo-derived viscose, cotton, plant-based absorbent core where the Seni is Cellulose/plastic core with unspecified waterproof coating layer, 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 Seni grade, at 42% 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 →
