Cosmetic Regulation: Navigating the Prohibition and Restriction of Nanomaterials

On 15th March 2024, the Official Journal of the European Union published Commission Regulation (EU) 2024/858 on the Cosmetics Regulation to prohibit and restrict the use of certain nanomaterials.

This significant update on nanomaterials reflects the EU’s commitment to environmental health and safety. Below, we will explore in depth the implications of this new regulation for the industry and what it means for both manufacturers and consumers in the European cosmetics landscape.

What are the prohibited substances?

This is the list of the new elements added to the list of substances banned in cosmetic products:

  • Styrene / Acrylates copolymer (nano), CAS no 9010-92-8
  • Sodium Styrene / Acrylates copolymer (nano), CAS no 9010-92-8
  • Copper (nano), CAS no 7440-50-8
  • Colloidal Copper (nano), CAS no 7440-50-8
  • Colloidal Silver (nano), CAS no 7440-22-4
  • Gold (nano), CAS no 7440-57-5
  • Colloidal Gold (nano), CAS no 7440-57-5
  • Gold Thioethylamino Hyaluronic Acid (nano), CAS no 1360157-34-1
  • AcetyI Thioethylamino-9 Colloidal gold (nano)
  • Platinum (nano), CAS no 7440-06-4
  • Colloidal Platinum (nano), CAS no 7440-06-4
  • AcetyI tetrapeptide-17 Colloidal Platinum (nano)


These nanomaterials, previously used in cosmetic products, are now subject to specific bans. This change will have a significant impact on product formulation and will require adaptation by manufacturers to comply with the new EU regulations.


What are restricted Nanomaterials?

The following entry for restricted substances is added:

  • Hydroxyapatite (nano), CAS No 1306-06-5: is restricted to 10 % in toothpastes and 0.465 % in mouthwashes.


When will the band and restriction of Nanomaterials enter in force? 

The implementation of this Regulation will enter into force on 4 April 2024.

And from 1 February 2025, any cosmetic product that includes these nanomaterials and does not comply with the relevant restrictions cannot be marketed in the EU, with a total ban from 1 November 2025.

This transition period gives manufacturers and the cosmetics industry time to adjust to the new regulations and ensure compliance with the standards set.
