Where these two actually differ
- We flag Volatile Organic Compounds (VOCs) and mineral oil vapor, Skin sensitization or contact dermatitis and Ingestion risk in children on the Star Ski Wax and not on the .
- We flag Fluorocarbon inhalation (PFAS precursor) and Dust inhalation during application on the and not on the Star Ski Wax.
- The Star Ski Wax is hydrocarbon ski wax (non-fluorinated) where the is wax-based ski base with possible fluorocarbon top coat, 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 Star Ski Wax is the one to buy.
- We are less certain about the grade, at 45% confidence against 78%, because it discloses less.
