EU Published Scientific Opinion on 4-Methylbenzylidene camphor (4-MBC) in cosmetics

On 10 May 2022, The European Commission’s Scientific Committee on Consumer Safety (SCCS) published their final conclusion on the safety of 4-methylbenzylidene camphor (4-MBC) in cosmetics. 

Conclusion of the opinion:

(1) In light of the data provided and taking under consideration the concerns related to potential endocrine disrupting properties of 4-Methylbenzylidene camphor (4-MBC), does the SCCS consider 4-MBC safe when used as a UV-filter in cosmetic products up to a maximum concentration of 4%?

The SCCS cannot conclude on the safety of 4-MBC, because the information provided is insufficient to fully evaluate potential genotoxicity.

Moreover, there is sufficient evidence that 4-MBC may act as an endocrine disruptor and has effects on both the thyroid and estrogen systems. Effects on the androgen system are not so evident, as only in vitro evidence is available.

Even if the genotoxic potential was excluded, the current re-evaluation of 4-MBC established a higher exposure level than in the previous Opinion. This would result in a lower MoS value, indicating that the use of 4-MBC at the maximum concentration of 4% in cosmetic ingredients would not be safe.

(2) Alternatively, what is according to the SCCS the maximum concentration considered safe for use of 4-MBC as a UV-filter in cosmetic products?

It is not possible to derive a maximum concentration for safe use of 4-MBC, because a genotoxicity potential cannot be excluded.

(3) Does the SCCS have any further scientific concerns with regard to the use of 4-MBC in cosmetic products?

The SCCS mandate does not address environmental aspects. Therefore, this assessment did not cover the safety of 4-MBC for the environment.
