Where these two actually differ

  • We flag Talc / Mineral absorbents, Fragrance / Fragrance allergens, Bacterial or fungal growth in container and Baking soda skin irritation on the Arm & Hammer and not on the Primally Pure.
  • We flag Skin irritation from magnesium hydroxide alkalinity on the Primally Pure and not on the Arm & Hammer.
  • The Arm & Hammer is Baking soda, cornstarch, talc or mineral-based absorbents 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 →
