Pack Crep Protect Spray Crep 200 ml + Déodorant pour chaussures Crep Fresh Linen 150 ml vs Waterproofing Wax for Leather: which is safer?

Where these two actually differ

• We flag Volatile Organic Compounds (VOCs) from propellant and solvents, Inhalation hazard from aerosol particulates, Coating degradation and microparticle shedding and Skin and eye contact irritation on the Crep Protect 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 Crep Protect.
• The Crep Protect is Protective spray coating (unspecified polymer/resin); aerosol formulation where the Nikwax is wax-based waterproofing, 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 Nikwax is the one to buy.
• We are less certain about the Crep Protect grade, at 35% confidence against 78%, because it discloses less.
