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 Swix.
- We flag Combustion/heating fume inhalation and Microplastic shedding during use on the Swix and not on the Swix.
- The Swix is Hydrocarbon-based ski wax (paraffin/synthetic blend) where the Swix is Bio-based paraffin blend wax, which is most of the difference in these two grades.
- These two are level, close enough that price and fit should decide it rather than our grade.
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 →
