Divergences in nanomaterials definition between the EU and France – Mandatory French notification scheme of nanomaterials

Article 2 of the Cosmetics Regulation defines a 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”. The revision of the definition of nanomaterial in light of the new recommendation of the European Commission is planned as part of the upcoming revision of the Cosmetics Regulation. However, the French government adheres to a different interpretation of the nanomaterial definition.
