On June 21, 2013, the European Commission (EC) began a consultation on the modification of the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) regulation annexes on nanomaterials. According to the EC, the objective of the initiative is to provide further clarity on how nanomaterials are addressed. The EC states that REACH must ensure a high level of health, safety, and environmental protection, while also permitting access to innovative products and promoting innovation and competitiveness. The EC intends to provide clearer REACH requirements for nanomaterials to ensure that industry demonstrates safe use in the registration dossiers in accordance with REACH Article 1(1). The EC expects to propose a possible amendment of the REACH annexes in 2013. Any proposed amendment would be accompanied by an impact assessment. Comments are due September 13, 2013.
