Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information
The substance CAS 2373-38-8 was evaluated as part of the compliance check procedure for which a final decision with the decision number CCH-D-2114489558-27-01/F was released by ECHA in November 2019. In the decision, registrants were required to provide short-term aquatic toxicity data by 22 August 2022 and long-term aquatic toxicity data (including aquatic invertebrate toxicity data) by 21 May 2024. In the previous version of the technical dossier, a read-across from docusate sodium (CAS 577-11-7) - for which a long-term toxicity data exists on Daphnia magna - was used as key information in the dossier of the substance (CAS 2373-38-8. In the final decision released, ECHA disagreed to use the read across data from docusate sodium as key information. The data from docusate sodium will now only be used as supporting information. New chronic aquatic invertebrate toxicity data will be presented in a subsequent dossier update, by 21 May 2024 at the latest, and evaluated in a group approach. Besides, until new aquatic chronic toxicity data become available, the derivation of PNEC values will be based on a conservative approach using the acute aquatic data on the substance CAS 2373-38-8 in combination with an AF of 1000 for freshwater and 10000 for marine water.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
