SWIX CERAF FC8XWS 20g Fluorocarbon Powder Wax RARE DISCONTINUED vs PS10 Yellow Wax: which is safer?

Where these two actually differ

• We flag PFAS (Per- and Polyfluoroalkyl Substances) inhalation and environmental persistence, Inhalation of wax powder and volatile compounds, Thermal degradation byproducts during iron application and Environmental bioaccumulation and persistence 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 Fluorocarbon powder wax (FC8XWS) where the Swix is Hydrocarbon-based ski wax (paraffin/synthetic blend), which is most of the difference in these two grades.
• The gap is 70 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 45% confidence against 72%, because it discloses less.
