Perfluorobutyl sulfonic acid and its salts will be listed in the EU REACH regulations

On September 3, 2019, ECHA issued a notice to include four chemical substances in the SVHC List of Substances of Very High Concern. It is now open for comment, and perfluorobutyl sulfonic acid (PFBS) and its salts are among them. REACH stipulates that when the product contains SVHC substances and the content exceeds 0.1%, it is required to notify ECHA or transmit information in the supply chain.
