IUCLID-Decoder: Python code to extract the chemical property data for the substances registered under REACH

Abstract

The IUCLID-Decoder is a package in python that enables users to extract chemical property data from registration dossiers that have been submitted to the EU Regulation on Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH). The data is extracted from files that the European Chemicals Agency (ECHA) offers for download. These files, the so called ‘REACH Study Results’ contain more than 4 million IUCLID 6 format (i6d) files with study results. The ‘iuclid_parser_utils.py’ function in the IUCLID Decoder package extracts and decodes the data and standardizes the units. The output is an SQLite database and (if set to ‘True’) an excel file with the database.
