Where these two actually differ
- We flag Skin irritation from alkalinity and Fragrance allergens or undisclosed fragrance compounds 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, mineral-based powder cosmetic 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 →
