Where these two actually differ
- We flag Fragrance allergens (undisclosed 'Cucumber Spa' fragrance components) and Aluminum salt exposure and skin irritation on the Carpe and not on the Primally Pure.
- We flag Skin irritation from magnesium hydroxide alkalinity on the Primally Pure and not on the Carpe.
- The Carpe is Typical antiperspirant/deodorant stick base, ingredients not fully disclosed 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 35 points, wide enough that this is not a close call, and the Primally Pure is the one to buy.
- We are less certain about the Carpe grade, at 45% confidence against 82%, because it discloses less.
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 →
