Several nanomaterials have been banned from use in cosmetics following amendments to Annex II of the EU Cosmetics Regulation (EC) No. 1223/2009, introduced in early 2024. These changes were based on recent opinions from the Scientific Committee on Consumer Safety (SCCS) regarding their safety in cosmetic applications.

A grace period was provided, ending in February 2025, after which the following nanomaterials can no longer be placed on the EU market:

• Styrene/acrylates copolymers (nano) – CAS 9010-92-7, including Sodium Styrene
• Copper and Colloidal Copper (nano) – CAS 7440-50-8
• Colloidal Silver (nano) – CAS 7440-22-4
• Gold (nano) – CAS 7440-57-5
• Gold Colloidal (nano) – CAS 7440-57-5
• Gold Thioethylamino Hyaluronic Acid (nano) – CAS 1360157-34-1
