Where these two actually differ
- We flag Fluorinated additives (PFAS-class compounds), Hydrocarbon solvent inhalation (spray form), Skin and eye irritation from direct contact and VOC off-gassing and environmental fate 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 Liquid hydrocarbon wax with unknown fluorinated additives or water-repellent treatment where the Swix is Hydrocarbon-based ski wax (paraffin/synthetic blend), 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 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 →
