Where these two actually differ

  • We flag Thermal decomposition / fume inhalation, Skin sensitization from undisclosed additives and Oxidative degradation and rancidity over time on the Swix 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 Swix.
  • The Swix is Ski wax base and glide coat, composition unspecified where the Swix is Hydrocarbon-based ski wax (paraffin/synthetic blend), which is most of the difference in these two grades.
  • The gap is 25 points, wide enough that this is not a close call, and the Swix is the one to buy.
  • We are less certain about the Swix grade, at 35% 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 →
