About
A fully fluorinated hydrocarbon — part of the PFAS family now being banned from cosmetics worldwide for environmental persistence.
Perfluorobutylcyclohexane (CAS 374-60-7) is a fully fluorinated cyclic hydrocarbon belonging to the broader per- and polyfluoroalkyl substances (PFAS) family. PFAS are characterized by extreme persistence in the environment ("forever chemicals"), bioaccumulation, and increasing regulatory restriction. The EU, California, Maine, Minnesota, and several other jurisdictions have enacted or are enacting cosmetic PFAS bans. Even where not yet prohibited, PFAS are strongly disfavored. This specific molecule shares the PFAS persistence profile. While acute toxicity is low, the broader environmental and policy profile makes it inappropriate for modern cosmetic formulation.
