GRAPHICAL ABSTRACT Abstract The essential use concept is a tool that can guide the phase-out of per-and polyfluoroalkyl substances (PFAS) and potentially other harmful substances of concern. This concept is a novel approach to chemicals management that determines whether substances of concern, such as PFAS, are truly essential for a given functionality. To assess the essentiality of a particular use case, three considerations need to be addressed: (1) the function (chemical, end use and service) that the chemical provides in the use case, (2) whether the function is necessary for health and safety and critical for the functioning of society and (3) whether
