Water & Stain Repellent 5.5oz vs Waterproofing Wax for Leather: which is safer?

Where these two actually differ

• We flag Inhalation risk from aerosol propellant and/or active ingredients, Volatile organic compound (VOC) off-gassing, Skin and eye contact irritation from undisclosed actives and PFAS bioaccumulation (graded separately at 20/100) on the Angelus 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 Angelus.
• The Angelus is Proprietary water and stain repellent coating 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 Angelus grade, at 35% confidence against 78%, because it discloses less.
