Where these two actually differ

  • We flag Fragrance allergens and sensitizers on the Cocofloss and not on the Reach.
  • We flag Fragrance allergens (if flavored variant), Nylon microplastics from floss shedding and Bacterial growth or biofilm on floss if stored wet on the Reach and not on the Cocofloss.
  • The Cocofloss is Plant-based waxed fiber floss where the Reach is nylon dental floss, likely uncoated or waxed, 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 →
