Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Justification for Read Across
Attached at section 13 is a category justification that explains the rationale for using data on a mixture of Dimethyl Esters (DBE), and Dimethyl Glutarate, to supplement the available data on Dimethyl Adipate.
Conclusion on classification
The lowest acute aquatic toxicity result was obtained on fish and gives a 96hLC50 value between 18 and 24 ppm (v/v). Considering that the relative density of the substance is around 1, the 96hLC50 value is expected to be between 18 and 24 mg/L. Therefore, the substance should be considered as harmful to the aquatic organisms tested.
Additionaly, the substance is readily biodegradable and has a low potential for bioaccumulation (i.e. logKow = 0.6 - 1.4). Therefore, the substance is not classified as dangerous for the environment according to European Directive 67/548/EEC and to Regulation (EC) No 1272/2008.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
