Kiwi grades Poor on our four-band scale.
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.
What Kiwi says and does about PFAS
We found no PFAS statement from Kiwi or its maker S.C. Johnson in the pages we could load. Kiwi safety data sheets list hydrocarbon solvents and propellants, and state that some exact composition details are withheld as a trade secret. We found no independent lab test, lawsuit or state disclosure naming Kiwi and PFAS.

Kiwi is one of the brands we researched by hand for our record of what every brand has published about PFAS, where the same question is answered for each of them in one line.
