Where these two actually differ
- We flag Respiratory irritation or fume inhalation during application and PFAS in water repellency treatment on the Nikwax and not on the Seventh Generation.
- We flag Fragrance allergens and Acute inhalation toxicity from spray aerosol on the Seventh Generation and not on the Nikwax.
- The Nikwax is wax-based waterproofing where the Seventh Generation is aqueous surfactant spray concentrate, 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 →
