4-MBC and Metabolites
UV-Filter used in cosmetics and sunscreen
4-methylbenzylidenecamphor (4MBC) is a UV-filter used in cosmetics and sunscreen.
Currently (2022) the scientific committee on consumer safety of the EU is not able to decide on the safe use of 4-MBC since the data on its genotoxicity is inconclusive.
Because of its known environmental toxicity 4-MBC is prohibited by some states (for example Palau) to protect coral reefs.
