REACH Study Results

REACH Study Results is a collection of non-confidential substance data that was submitted to ECHA under the REACH regulation. ECHA believes that making these data downloadable will be yet another step forward towards the goals of REACH - both in terms of improving the safe use of chemicals, for example through improved safety data sheets, and, the development and use of alternative methods. The REACH Regulation stipulates that data are to be “made publicly available, free of charge”.

REACH Study Results contains results from studies that relate to physical-chemical properties, environmental fate and pathways, and, ecotoxicology and toxicological information. The data is derived from data that are already accessible on the, ECHA website. However, in REACH Study Results, only the results of studies are presented, and in a reduced form. On the ECHA website data can be viewed one substance at a time, but REACH Study Results allows data to be read in bulk by importing the data in to a local installation of IUCLID, and then using the IUCLID 6 REST Public API, the IUCLID Data Extractor or, an advanced IUCLID search tool. The results are made available to download in an archive that contains dossiers in IUCLID format (i6z). Data for approximately 23,000 substances is included. A list of the substances is provided in Excel format here  (2.5 MB). This way of delivering REACH Study Results allows users to import in to a local instance of IUCLID, only the substances in which they are interested. It is recommended to use the most recent version of IUCLID, available here

The data may be downloaded only after acceptance of the terms and conditions, the provision of contact details, and the purpose for which the data will be used. Before using the data, you are advised to read carefully the terms and conditions because it states, among other things, the way in which the data may be used. For example, the data may not be used for registration under the REACH Regulation. Moreover, it should be recalled that the data derives from REACH registration dossiers, and as such there are no guarantees/warranties pertaining to its quality and fitness for purpose.

REACH Study Results is available for download here (9 GB).

To check the integrity of a download, compare the checksum of the downloaded archive with the checksum on the page here.
