Where these two actually differ
- We flag Fragrance allergens and formaldehyde releasers, Aluminum systemic absorption, Inhalation exposure from aerosol spray and Skin irritation and barrier disruption on the Certain Dri and not on the Primally Pure.
- We flag Skin irritation from magnesium hydroxide alkalinity on the Primally Pure and not on the Certain Dri.
- The Certain Dri is aluminum-based aerosol formulation with active antiperspirant (aluminum salts) and 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 →
