Fabric Guard Trigger Sprayer THR30606 vs Waterproofing Wax for Leather: which is safer?

Where these two actually differ

• We flag Volatile organic compounds (VOCs) from solvent and propellant, Respiratory or skin irritation from undisclosed active ingredients, Skin or eye contact injury from spray mist and Contamination of food contact surfaces or dishware on the 303 Products 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 303 Products.
• The 303 Products is fabric guard coating, composition unspecified 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 303 Products grade, at 35% confidence against 78%, because it discloses less.
