is an Aggregator.

It is part of the NAMs collection.

eChemPortal (The Global Portal to Information on Chemical Substances) is a free public portal run by the Organisation for Economic Co-operation and Development (OECD), developed in collaboration with the European Chemicals Agency (ECHA), that provides simultaneous search across chemical hazard and risk information prepared for government chemical programmes at national, regional, and international levels. It covers existing and new industrial chemicals, pesticides, and biocides, and supports search by substance name or number, by chemical property and endpoint data (structured according to the OECD Harmonised Templates), and by GHS or national hazard classification, linking to about 34 participating data sources.

eChemPortal (The Global Portal to Information on Chemical Substances)

Overview

eChemPortal provides free public access to information on chemical properties and direct links to collections of information prepared for government chemical programmes at national, regional, and international levels. It is an effort of the OECD with contributions from governments and other stakeholders, developed in collaboration with the European Chemicals Agency (ECHA), and was launched in 2007. Because it brings together regulatory hazard data on structurally related substances, it is widely used to gather source data for grouping and read-across.

Data Content

  • About 34 participating data sources, including ECHA REACH registration data and the ECHA C&L inventory, OECD Existing Chemicals (HPV / SIDS IUCLID), Canada’s Categorization Results (CCR), Japan’s J-CHECK and GHS classification results, US EPA IRIS, ECOTOX, and the CompTox Chemicals Dashboard, EFSA OpenFoodTox, HSDB at PubChem, ICSC, INCHEM, and IPCHEM.
  • Substance search by name or identifier (for example CAS number) across all sources.
  • Property search over physical-chemical, environmental fate, ecotoxicity, and toxicity endpoint data from sources that provide structured data (OECD Harmonised Templates).
  • Classification search over GHS and national/regional hazard classification results.
  • Exposure and use information on chemicals, and schedules of assessments from government programmes.
