Mink Oil Leather Shoe Protectant and Conditioner vs Waterproofing Wax for Leather: which is safer?

Where these two actually differ

• We flag Volatile organic compounds (VOCs) / formulation off-gassing, Coating degradation and reapplication frequency and Unconfirmed PFAS in water-repellent matrix on the Sof Sole and not on the Nikwax.
• We flag Respiratory irritation or fume inhalation during application and PFAS in water repellency treatment on the Nikwax and not on the Sof Sole.
• The Sof Sole is mink oil leather conditioner and protectant where the Nikwax is wax-based waterproofing, which is most of the difference in these two grades.
• These two are level, close enough that price and fit should decide it rather than our grade.
• We are less certain about the Sof Sole grade, at 45% confidence against 78%, because it discloses less.
