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 Holmenkol.
- We flag Hydrocarbon volatilization (inhalation during application), Oxidative degradation and byproducts and Environmental persistence (non-aquatic toxicity) on the Holmenkol and not on the Swix.
- The Swix is Hydrocarbon-based ski wax (paraffin/synthetic blend) where the Holmenkol is Hydrocarbon wax blend, which is most of the difference in these two grades.
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 →
