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 skin sensitization, Residual surfactant irritation on fabric, Eye and mucous membrane irritation and Ingestion risk from spray bottle misuse on the Shout and not on the Nikwax.
- The Nikwax is wax-based waterproofing where the Shout is Aqueous surfactant solution in spray bottle, which is most of the difference in these two grades.
- We are less certain about the Shout grade, at 45% confidence against 78%, because it discloses less.
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 →
