Where these two actually differ
- We flag Undisclosed additives (UV stabilizers, anti-caking agents, performance enhancers), Inhalation risk from dust or fumes, Skin sensitization from unknown fragrance or chemical additives and Thermal degradation of undisclosed components on the and not on the Swix.
- We flag Combustion by-products during hot application, Skin and eye contact irritation, Ingestion toxicity (accidental exposure) and Microabrasive particulates from worn base or scraping on the Swix and not on the .
- The is Wax formulation, unspecified composition where the Swix is Hydrocarbon-based ski wax (paraffin/synthetic blend), which is most of the difference in these two grades.
- The gap is 50 points, wide enough that this is not a close call, and the Swix is the one to buy.
- We are less certain about the grade, at 25% confidence against 72%, 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 →
