What's new 

The OECD is pleased to announce the release of eChemPortal version 3.0. This new version includes a modernisation of the user interface architecture, a refreshed design, improved navigation and the alignment of eChemPortal to OECD Harmonised Template (OHT) 2018. The user experience is now more fluid and the user can search for chemical information more efficiently.

New features include quick search functionality from the homepage, filtering and sorting on results tables, and a preliminary indication of the number of results expected in a search by chemical properties. The searches also have been harmonised to be more intuitive for the user. 

Free webinars and training events will be organised upon request to
