Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Conclusion on classification
In accordance with the criteria for classification as defined in Annex I, Regulation (EC) No 1272/2008, the substance requires classification with respect to the environment as Chronic Category 2 (H411: Toxic to aquatic life with long lasting effects).
This is based on the 96 h LC50 of 3.9 mg/L in Danio rerio and the 48 h EC50 of 6.5 mg/L in Daphnia magna, coupled with the fact that the substance is not considered to be rapidly degradable.
There does not appear to be sufficiently robust information available to warrant the use of the reported EC50 value in algae of 0.9 mg/L for classification purposes concerning environmental toxicity hazard; this is an estimated effective concentration and as a conclusion from the hazard assessment, the toxicity of diphenyl carbonate towards algae is considered be with an EC50 >1 mg/L.
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.
