Is 4-Methylbenzylidene Camphor banned in Europe?

Banned in EU

Yes: 4-MBC is now banned in EU cosmetics. Regulation (EU) 2024/996 moved it from the approved UV-filter list to the prohibited list as an endocrine disruptor, effective May 2025. It was never an FDA-approved US sunscreen filter to begin with.

CAS: 36861-47-9 Also seen as: 4-MBC, Enzacamene, 4-Methylbenzylidene camphor, MBC

What the EU does

Banned, and recently so. 4-MBC was for years an authorized UV filter in the EU, sitting on Annex VI of the Cosmetics Regulation. Regulation (EU) 2024/996 reversed that: it removed 4-MBC from the approved filter list and added it to Annex II, the list of substances prohibited in cosmetics. Products containing it could no longer be placed on the EU market from May 1, 2025, and could no longer be made available from May 1, 2026.

The reason was endocrine disruption. The EU's Scientific Committee on Consumer Safety concluded in a 2022 opinion that no safe concentration of 4-MBC could be established, citing evidence that it disrupts both the thyroid and estrogen systems, plus insufficient data to rule out genotoxicity. This is the precautionary default in action: faced with an endocrine signal and a data gap, the EU pulled the ingredient rather than set a limit. The ban reaches beyond sunscreen to any product with UV protection, including SPF moisturizers, foundations, and lip balms.

What the US does

Not approved as a US sunscreen filter, and it never was. 4-MBC does not appear in the FDA's over-the-counter sunscreen monograph, so it cannot be used as an active UV filter in American sunscreens. In the US system, sunscreen filters are regulated as over-the-counter drugs, and 4-MBC simply never cleared that bar.

So the transatlantic contrast here is unusual. This is not a case of the US permitting something the EU banned. Both jurisdictions now keep 4-MBC out of sunscreen, by different routes: the EU banned a filter it once allowed, while the US never approved it in the first place. It can still turn up in imported or gray-market products, which is the main reason to know the name.

Products that commonly contain it

4-MBC was used as a UVB filter, mostly in European-market sun and SPF products before the ban. Watch for it in older or imported stock such as:

  • Sunscreen lotions and sprays (pre-2025 EU formulations)
  • Daily moisturizers and day creams with SPF
  • Tinted foundations and BB creams with sun protection
  • SPF lip balms and after-sun products

What to look for on a label

On an INCI list, this filter hides behind several names:

  • "4-Methylbenzylidene Camphor" (the INCI name)
  • "4-MBC" or "MBC", the common shorthand
  • "Enzacamene", the international nonproprietary name
  • If you see any of these on an SPF product, it predates or sidesteps the 2025 EU ban

Frequently asked questions

Is 4-MBC banned in Europe?

Yes. Regulation (EU) 2024/996 moved 4-methylbenzylidene camphor from the approved UV-filter list to Annex II (prohibited). It could no longer be placed on the EU market from May 1, 2025, and no longer made available from May 1, 2026.

Why did the EU ban 4-MBC?

The Scientific Committee on Consumer Safety found in 2022 that no safe concentration could be established, citing endocrine disruption affecting the thyroid and estrogen systems and insufficient genotoxicity data.

Is 4-MBC used in US sunscreens?

No. It is not in the FDA's sunscreen monograph and was never approved as a US UV filter, so it should not appear in American sunscreens, though it can show up in imported products.

What products contained 4-MBC?

Mostly European-market UVB sunscreens and SPF products: lotions, SPF moisturizers, tinted foundations, and lip balms made before the 2025 ban.
