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 Shout.
- We flag Fragrance allergens and respiratory irritation, Surfactant skin and eye irritation, Optical brightener bioaccumulation and Ingestion hazard (accidental) on the Shout and not on the Nikwax.
- The Nikwax is wax-based waterproofing where the Shout is aqueous surfactant blend, plastic trigger sprayer, 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 →
