Surface modifier, as a declared use for PFAS
30 companies have told Minnesota that they put PFAS into products to serve this purpose, in 435 filings covering 162 products and 15 distinct compounds. This is the field that makes the set worth reading, because it records PFAS being chosen for a job rather than turning up as a contaminant.

Other declared uses
Source, manufacturer filings made to the Minnesota Pollution Control Agency under the state’s PFAS in Products law and published through PRISM, run by the Interstate Chemicals Clearinghouse. These are the manufacturers’ own statements, not our grades and not laboratory results. A filing covers the product as sold in Minnesota and says nothing about products or formulations the company did not file. Reporting was still open when this was pulled, so absence from the set is not evidence a product is PFAS-free.
