Omnibus IV: new ingredients banned in cosmetics

November 5, 2021 – On November 3, 2021, the European Commission published the Omnibus Act IV. Regulation (EU) 2021/1902 aims at including in Annex II to the EU Cosmetics Regulation those substances that have been classified as CMR in the latest amendment of the CLP Regulation, dated May 19, 2020.

The bans will apply as of March 1, 2022! They will affect not only new products but also cosmetics already on shelves on the EU market that will need to be withdrawn.

Even though the prohibition of using CMR substances automatically applies to cosmetic products (Article 15 of Regulation EU 1223/2009), their incorporation in Annex II ensures legal certainty: all the relevant information is available in a single document.

Let’s see which ingredients will be banned – Read the paragraphs below to be prepared for the deadline of March 1, 2022!

Butylphenyl Methylpropional (Lilial) – CAS No. 80-54-6

Lilial is an allergen commonly used in cosmetic formulations. Currently, it is included in Annex III to the EU Cosmetics Regulation: it must be mentioned in the list of ingredients when its concentration exceeds 0,001% in leave-on products and 0,1% in rinse-off products.

In 2020, it has been classified as CMR 1B because, based on animal studies, it could be toxic for reproduction, as it may damage fertility. Hence, according to Omnibus Act IV, it is moved to Annex II (prohibited substances) to the EU Cosmetics Regulation.

As of March 1, 2022, cosmetics containing Butylphenyl Methylpropional must be off shelves. It is time for manufacturers to reformulate their cosmetics with Lilial-free fragrances.

Zinc Pyrithione – CAS No. 13463-41-7

Until now, Zinc Pyrithione was listed in Annexes III and V to the EU Cosmetics Regulation. Thus, it was allowed to be used:

  • In leave-on hair products at a maximum concentration of 0,1% when it is not used as a preservative;
  • As a preservative up to a maximum concentration of 1,0% in rinse-off hair products and of 0,5% in other rinse-off cosmetics. It is not allowed to be used in oral hygiene products.

Zinc Pyrithione has been classified as CMR 1B (toxic for reproduction) and on April 11, 2019, a request to keep using it as an anti-dandruff in rinse-off hair products up to a maximum concentration of 1% by way of exception was submitted.

According to Article 15.2 of the EU Cosmetics Regulation, the use of CMR 1B substances in cosmetic products may be exceptionally permitted if:

  • They meet the food safety requirements foreseen in the Regulation (EC) 178/2002;
  • No suitable alternative substances are available;
  • The request concerns a specific use with a known product exposure;
  • The Scientific Committee on Consumer Safety (SCCS) has declared safe the use of the ingredient for that specific use.


In light of the above, in its opinion of March 03-04, 2020, the SCCS concluded that Zinc Pyrithione is safe when used as an anti-dandruff in rinse-off hair products up to a maximum concentration of 1%. However, Zinc Pyrithione does not meet all the conditions listed in Article 15.2 – specifically, the lack of available alternative substances has not been demonstrated – therefore, its use in cosmetics cannot be granted by way of exception. In conclusion, also Zinc Pyrithione has been added to Annex II of the EU Cosmetics Regulation and the related entries in Annexes III and V have been deleted.

As of March 1, 2022, cosmetics containing Zinc Pyrithione will not be allowed on the EU market – Manufacturers must act now to be compliant with the EU Law.
