Where these two actually differ
- We flag Fragrance allergens and sensitizers on the Cocofloss and not on the Listerine.
- We flag Microplastics or fiber shedding into the mouth on the Listerine and not on the Cocofloss.
- The Cocofloss is Plant-based waxed fiber floss where the Listerine is Nylon monofilament fiber, which is most of the difference in these two grades.
- The gap is 25 points, wide enough that this is not a close call, and the Cocofloss 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 →
