Where these two actually differ

  • We flag Fragrance allergens and skin sensitization, 1,4-dioxane as fragrance contaminant and Skin irritation from exfoliating acids (if AHA content is high) on the Kosas and not on the Puracy.
  • We flag Fragrance allergens, Formaldehyde releasers and Glass container breakage on the Puracy and not on the Kosas.
  • The Kosas is Standard cosmetic formulation (deodorant base) where the Puracy is Glass jar; water-based cream formula, 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 Puracy is the one to buy.

Both products run through the same public rubric: 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 →
