Where these two actually differ
- We flag Skin irritation from magnesium hydroxide alkalinity on the Primally Pure and not on the Schmidt's.
- We flag Fragrance allergens and essential oils, Skin irritation from mineral salts and baking soda and Coconut oil rancidity and microbial growth on the Schmidt's and not on the Primally Pure.
- The Primally Pure is mineral-based powder blend (arrowroot, magnesium hydroxide, mica) where the Schmidt's is Natural mineral salts, coconut oil, arrowroot starch, 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 →
