Beaver DamFast Wax vs PS10 Yellow Wax: which is safer?

Where these two actually differ

• We flag Volatile organic compounds (VOCs) / off-gassing, Heavy metal contamination in natural wax components, Skin and respiratory irritation from additives and Thermal stability and degradation products on the Beaver Wax 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 Beaver Wax.
• The Beaver Wax is Unknown wax composition where the Swix is Hydrocarbon-based ski wax (paraffin/synthetic blend), which is most of the difference in these two grades.
• The gap is 25 points, wide enough that this is not a close call, and the Swix is the one to buy.
• We are less certain about the Beaver Wax grade, at 25% confidence against 72%, because it discloses less.
