Cross Country Ski Grip vs PS10 Yellow Wax: which is safer?

Where these two actually differ

• We flag Volatile organic compounds (VOCs) from unknown binders, Skin irritation or sensitization from contact, Microplastic or wax particle shedding into snow and water and Unknown fluorocarbon content (PFAS-adjacent) on the Holmenkol 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 Holmenkol.
• The Holmenkol is Wax-based ski grip (likely hydrocarbon blend; coating composition unspecified) 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 Holmenkol grade, at 35% confidence against 72%, because it discloses less.
