Where these two actually differ

  • We flag Skin irritation from magnesium hydroxide alkalinity on the Primally Pure and not on the Salt & Stone.
  • We flag Fragrance allergens (essential oils) and Microbial growth in water-based formulation on the Salt & Stone and not on the Primally Pure.
  • The Primally Pure is mineral-based powder blend (arrowroot, magnesium hydroxide, mica) where the Salt & Stone is Water, gelling agents, mineral powders, essential oils, 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: 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 →
