Perfluorobutanesulfonic acid (PFBS) is a chemical compound with a four carbon fluorocarbon chain and a sulfonic acid functional group. As an anion it functions as a stable fluorosurfactant because of the strength of carbon–fluorine bonds.
Since June 2003, 3M has used PFBS as a replacement for the persistent, toxic, and bioaccumulative perfluorooctanesulfonic acid (PFOS) in its Scotchgard stain repellents.[4]3M markets surfactant with PFBS in two fluorosurfactants.[5]
PFBS has a half-life of a little over one month in people, much shorter than PFOS with 5.4 years.[6] PFBS is persistent in the environment. Studies have not yet been specifically conducted to determine safety in humans.
