The European Union is to make the labeling of nanomaterials in cosmetics mandatory according to Chemistry World.

“The cosmetic regulation states that all ingredients present in the product in the form of nanomaterials should be clearly indicated in the list of ingredients, by inserting the word ‘nano’ in brackets after the ingredient listing. The ruling 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’.
