4-Methylbenzylidene Camphor (4-MBC) in cosmetics
4-Methylbenzylidene Camphor, also called 4-MBC, is prohibited in cosmetic products in the EU under Regulation (EU) 2024/996. The rule follows an SCCS opinion that could not conclude on safety because the data were insufficient to fully evaluate potential genotoxicity.

What the scientific opinion found
The Scientific Committee on Consumer Safety reviewed 4-MBC and could not conclude on its safety because the information supplied was insufficient for a full evaluation of potential genotoxicity. The Committee also reported evidence that 4-MBC may act as an endocrine disruptor, with effects on thyroid and estrogen systems.
What changed in the EU
Regulation (EU) 2024/996 adds 4-Methylbenzylidene Camphor to the list of prohibited cosmetic substances. Products containing it could not be placed on the EU market from 1 May 2025 and could not be made available on that market from 1 May 2026.
What this does not establish
A regulatory prohibition does not identify every product sold in every country, measure a person's exposure, or diagnose an effect. Product availability may also depend on territory and the transition dates in the regulation. This record is not personal medical advice.
