OECD releases new data on nanomaterials – registrants asked to consider the information

The OECD’s Working Party on Manufactured Nanomaterials has started the publication of new data on 11 nanomaterials. Registrants are reminded to consider this information and to update their dossiers accordingly. The dissemination of hazard information is for the following 11 nanomaterials in IUCLID format:

  • Fullerenes;
  • single-walled carbon nanotubes;
  • multi-walled carbon nanotubes;
  • silver;
  • gold;
  • dendrimers;
  • silicon dioxide (six different forms);
  • nanoclays;
  • titanium dioxide (six different forms);
  • cerium dioxide; and
  • zinc oxide.

The new information is the outcome of an experimental programme where 11 commercially viable nanomaterials have been used to generate results from 780 studies relating to their intrinsic properties. The work has already given significant input to the specific amendments to the existing test guidelines and generated numerous nano-specific (eco)toxicological data. It will continue to be a cornerstone of the work around risk assessment of nanomaterials. “We welcome more nano-specific data becoming publicly available. Such data is highly sought after, not only in ongoing research projects and international work, but also as a contribution for better transparency of safety information on existing nanomaterials on the market,” says ECHA Executive Director Geert Dancet. ECHA encourages registrants of these substances to carefully assess the new data. When relevant, they should take this information into account and update their registration dossiers accordingly to ensure the safe use of their substances. ECHA is actively involved in the OECD work and chairs the Steering Group on Testing and Assessment of Manufactured Nanomaterials. The newly published data has been developed and generated by delegations and industry under this steering group. The testing programme was launched in 2007 to conduct specific tests relevant to human health and environmental endpoints on manufactured nanomaterials. The aim was to assess the applicability of the existing test guidelines to nanomaterials and to provide useful information on intrinsic properties of manufactured nanomaterials.
