Where these two actually differ
- We flag Mineral oil residue buildup on floors, Eye and skin irritation from spray and Inhalation of mineral oil mist on the Murphy Oil Soap 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 Murphy Oil Soap.
- The Murphy Oil Soap is mineral oil and soap surfactants in aqueous spray where the Nikwax is wax-based waterproofing, which is most of the difference in these two grades.
