Where these two actually differ
- We flag Inhalation exposure during application, Fluorine-based performance additives (non-PFAS designation), Skin sensitization from hydrocarbon residue and Coating delamination and base damage over time on the Start 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 Start.
- The Start is Ski/snowboard glide wax or base treatment where the Swix is Hydrocarbon-based ski wax (paraffin/synthetic blend), which is most of the difference in these two grades.
- We are less certain about the Start 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 →
