Where these two actually differ
- We flag Azo dyes (cationic), Skin irritation or allergic contact dermatitis and Microfiber shedding on the Carbona and not on the Nikwax.
- We flag Respiratory irritation or fume inhalation during application and PFAS in water repellency treatment on the Nikwax and not on the Carbona.
- The Carbona is nonwoven polyester sheets with cationic dyes where the Nikwax is wax-based waterproofing, which is most of the difference in these two grades.
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 →
