The EU Cosmetics Regulation defines nanomaterial as an insoluble or biopersistant and intentionally manufactured material with one or more external dimensions, or an internal structure, on the scale from 1 to 100 nm.
However, as there are different definitions of nanomaterials at EU levels, changes to the individual definitions is still under discussion.
Cosmetic products containing nanomaterials must be notified to the European Commission via the Cosmetic Products Notification Portal (CPNP) by the person responsible, six months prior to being placed on the market, in addition to notification under Art. 13. Additionally, the product’s specifications (size, physical and chemical properties), a toxicological profile, safety data and exposure conditions of the nanomaterials must be provided.
All ingredients in the form of nanomaterials must be listed clearly on the list of ingredients. The name of these ingredients must be followed by the term “nano” in brackets. Nanomaterials that have been classified as safe by the European Commission and are listed in the Annexes of the Regulation as colorants, UV filters or preservatives are not subject to notification prior to being placed on the market. However, labelling with the term “nano” still applies.
You will find information on nanomaterials on the website of the European Commission on cosmetics.
