The IUCLID application (International Uniform Chemical Database) is used by the chemical industry worldwide to capture and manage data on the chemical compounds they produce. Marketing these substances in the EU that fall under the REACH Regulation requires submission of the IUCLID data to the associated authority, the European Chemicals Agency (ECHA)

In the running it became necessary to capture essential data specific to nanomaterials such as zeta potential or dustiness in the forms. On behalf of the OECD Working Party on Manufactured Nanomaterials (WPMN), researchers from the European Joint Research Centre from the Institute for Health and Consumer Protection (JRC-ICHP) developed a series of drafts which were summarised in 13 final documents and subsequently integrated into the IUCLID database.

The current version of IUCLID 5.5 software is available under So far, in previous versions of IUCLID nano-specific physical and chemical data could be reported with workarounds. Thanks to the work of the JRC scientists reporting these important properties is considerably simplified which in long term will lead to improvement of data quality and reliability.
