Does Secret deodorant have PFAS?
PFAS Authority is a scoring system, not a laboratory. We do not test products ourselves. Grades are model-based, built from published ingredients, materials, certifications, brand disclosures and third-party lab results where they exist. See the rubric.
We graded 8 Secret deodorant products, averaging Good (63/100). 2 of them grade Good or better. Against the other 31 deodorant brands we grade, where the middle brand sits at 75/100, Secret is worse than typical.
