Perfluorohexane sulfonic acid (PFHxS) is a highly surface-active perfluorinated compound with chemical properties similar to perfluorooctane sulfonic acid (PFOS). Following the ban on PFOS by the Stockholm Convention in 2009, PFHxS has been widely used as a substitute in various products. However, PFHxS is persistent in the environment, capable of long-range transport, and may cause developmental toxicity, neurotoxicity, hepatotoxicity, and reproductive toxicity. At the 10th Conference of the Parties to the Stockholm Convention (SC COP-10), PFHxS, its salts, and related compounds were listed in Annex A of the Convention for elimination, with no exemptions allowed.

EPD (Environmental Product Declaration) is a Type III environmental declaration that complies with ISO 14025 standards. It is based on a Life Cycle Assessment (LCA) of a product or service, quantitatively presenting its environmental impact. It serves as a voluntary declaration of the product's environmental impact throughout its life cycle. The international EPD system originated in Sweden and is operated by EPD International AB. Based on internationally standardized regulations, EPD is a globally recognized, quantifiably comparable, trustworthy, and verifiable technical document providing environmental performance data to various stakeholders. The EPD system is currently the most widely used environmental declaration worldwide, encompassing nearly all products and services.
