Where these two actually differ
- We flag Fragrance allergens or undisclosed fragrance components and Mechanical irritation from crystal size and shape on the Credo Beauty and not on the Puracy.
- We flag 1,4-dioxane (surfactant byproduct), Fragrance allergens (undisclosed components) and Bacterial or mold growth in refill container on the Puracy and not on the Credo Beauty.
- The Credo Beauty is salt crystals, mineral-based scrub where the Puracy is aqueous surfactant-based liquid shampoo, which is most of the difference in these two grades.
- These two are level, close enough that price and fit should decide it rather than our grade.
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 →
