Where these two actually differ

  • We flag Fragrance allergens and contact sensitization, Aluminum absorption via skin and Propellant inhalation (aerosol form) on the Old Spice and not on the Primally Pure.
  • We flag Skin irritation from magnesium hydroxide alkalinity on the Primally Pure and not on the Old Spice.
  • The Old Spice is aluminum/starch base, propellant, fragrance where the Primally Pure is mineral-based powder blend (arrowroot, magnesium hydroxide, mica), 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 Primally Pure is the one to buy.

Both products run through the same public rubric, which covers materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
