The aim was to continue the checks carried out over several years with Responsible Persons regarding the compliance of nano-raw materials and finished products containing them, in two respects:
• Documentary checks: compliance of nano-labelling (an important aspect of consumer information), specific declaration on the CPNP portal, verification that the nano-nature of the product has been taken into account in product safety reports, verification of the maximum concentration of nanomaterials in the finished product, and verification of physicochemical criteria, including the size of primary particles
• Sampling: testing for unauthorised nanomaterials or those that do not comply with regulatory requirements
