Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Both components of the Reaction mass of dipropylene glycol dibenzoate (DPGDB) and diethylene glycol dibenzoate (DEGDB) were demonstrated to be readily biodegradable in a Modified Strum Ready Biodegradability test. DPGDB achieved 62% degradation by day 12, meeting the 10 -day window criterion and 85% by test day 28. In addition, DEGDB achieved 71% after 10 days and 93% by test termination. Based on these data, the reaction mass of DPGDB and DEGDB is expected to be readily biodegradable.
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.
