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 Scotchgard.
- We flag Skin and eye irritation from surfactants, Respiratory irritation from spray aerosol inhalation, Dye transfer or fabric degradation and Ingestion hazard in children or pets on the Scotchgard and not on the Nikwax.
- The Nikwax is wax-based waterproofing where the Scotchgard is aqueous cleaner solution, surfactants, which is most of the difference in these two grades.
Both products run through the same public rubric: 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 →
