Zest Review, Is Zest Non-Toxic?
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.
Across 7 graded products, Zest averages Excellent (77/100). On disclosure, the brand says nothing publicly about PFAS. 7 of its products grade Good or better. Grades are model-based estimates, not lab results.
