Perfluorobutanesulfonic acid
What is Perfluorobutanesulfonic acid?
Perfluorobutanesulfonic acid (PFBS) is a chemical from the perfluoroalkyl and polyfluoroalkyl substances (PFAS) group. It is a man-made compound typically used in industrial applications, especially in the coating of products to make them resistant to stains and water.
While PFBS can be found in some consumer goods, its primary use is industrial. Current research indicates that PFBS is less bioaccumulative than some longer-chain PFAS compounds, but concerns are noted about its persistence in the environment and potential health effects.
If you see perfluorobutanesulfonic acid on a label, it is likely part of a water or stain-resistant treatment. Its presence might reflect manufacturing processes rather than direct exposure in a final consumer product.
Commonly found in: industrial coatings, stain-resistant treatments, water-resistant surfaces
What to watch
- PFBS is persistent in the environment, raising concerns about its long-term ecological impact.
PFAS chemicals, including PFBS, are under review by the FDA for potential health risks due to their persistence.
Studies show that while PFBS is less bioaccumulative, its persistence still raises environmental and health concerns.
PFBS is a synthetic compound and does not contain animal-derived ingredients.
