Per- and Polyfluoroalkyl Substances (PFAS), commonly known as "forever chemicals", feature extremely stable carbon-fluorine bonds, high bioaccumulation potential and suspected endocrine disrupting properties, leading to stringent regulatory restrictions worldwide. According to OECD statistics, the PFAS family comprises over 10,000 substances. Fluoropolymers including Polytetrafluoroethylene (PTFE), FEP, PFA, PVDF and PCTFE are widely applied in cardiovascular catheters, implant coatings, pacemaker wire insulation, as well as sterile high-barrier packaging for medical devices.

Per- and polyfluoroalkyl substances (PFAS) are increasingly becoming a focal point of global concern due to their potential long-term impacts on the environment and human health. As a class of synthetic chemicals characterized by high stability and widespread applications, PFAS are facing increasingly stringent regulatory scrutiny in the cosmetics sector. This article explores the physicochemical properties and potential health risks of PFAS, and systematically reviews the evolving global regulatory landscape related to their use in cosmetics. It aims to help cosmetic enterprises gain a comprehensive understanding of regulatory requirements, mitigate compliance risks, enhance product safety, and strengthen competitiveness in international markets.
