Where these two actually differ
- 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 .
- We flag PFAS in glide additives, Volatile organic compounds (VOCs) from hydrocarbon base and additives, Inhalation of wax dust and fine particles and Skin and eye irritation from direct contact on the and not on the Swix.
- The Swix is Hydrocarbon-based ski wax (paraffin/synthetic blend) where the is hydrocarbon wax blend with unspecified treatment/glide agents, which is most of the difference in these two grades.
- The gap is 60 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 45% 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 →
