NF2 Cera-Flon Wax vs PS10 Yellow Wax: which is safer?

Swix PS10 Yellow Wax is the clear pick. NF2 Cera-Flon Wax carries a failing PFAS grade, and we never recommend buying a failing product.

Where these two actually differ

  • We flag Fluoropolymer composition and thermal stability, Undisclosed additives and wax base composition, Off-gassing and VOC release and Reproductive or developmental harm potential (PFAS-related) on the Cera F 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 Cera F.
  • The Cera F is Wax blend, fluoropolymer status unclear where the Swix is Hydrocarbon-based ski wax (paraffin/synthetic blend), which is most of the difference in these two grades.
  • The gap is 50 points, wide enough that this is not a close call, and the Swix is the one to buy.
  • We are less certain about the Cera F grade, at 28% 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 →
