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 Woolite.
- We flag PFAS in water-repellent or soil-release actives, 1,4-dioxane contamination in surfactants and Aquatic toxicity from surfactants on the Woolite and not on the Nikwax.
- The Nikwax is wax-based waterproofing where the Woolite is Aqueous spray formulation (likely water, surfactants, fabric-care actives), which is most of the difference in these two grades.
- We are less certain about the Woolite 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 →
