It is to verify the legal compliance with the mandatory labelling declaration for the nanomaterials contained in consumer goods that UFC-Que Choisir had 16 food and cosmetic products analyzed by a laboratory. Here is the result, according to the French consumer association: 8 products analyzed out of 10 do not mention the presence of nanoparticles. UFC decided to file a complaint, in particular against five cosmetic brands. Meanwhile, DGCCRF (French General Directorate for Competition Policy, Consumer Affairs, and Fraud Control) made the results of their market inspections available to the public. And they provide evidence of many cases of non-compliance with regulations.
