Get IUCLID data

On these pages, ECHA publishes the following non-confidential data in IUCLID 6 format.

  • Reference substances
    A Reference substance is a software entity in IUCLID that is used to define the identity of a Substance, or a component within it, in such a way that the definition may be re-used in more than one location. This provides consistency and avoids duplication of work. A Reference substance contains chemical identifiers and structural information. Reference substances can be created in IUCLID but you may find it more efficient to take a ready-made one from this collection and import it in to IUCLID. There are thousands available, but it is possible to search for and download only what you need.
  • IUCLID inventories

    Chemical inventories are a type of data in IUCLID that is used as a source of chemical identifiers that have been defined outside IUCLID. A link can be created from a Reference substance to an inventory entry. This provides the Reference substance with information on chemical identity in a re-usable way, and in a standard format.

    For example, the EC Inventory contains chemical identifiers such as EC numbers, CAS numbers and molecular formulae. It is delivered with IUCLID 6 Desktop, but not with IUCLID 6 Server. The EC Inventory is available for download here.

  • REACH study results
    REACH study results is a collection of non-confidential substance data that was submitted to ECHA under the REACH regulation. It contains results from studies that relate to physical-chemical properties, environmental fate and pathways, and ecotoxicology and toxicological information.
