Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information
Additional information
Hydrolysis and phototransformation in water are expected to be insignificant. However, there is evidence of phototransformation in air. The European Union Risk Assessment Report for BBP gives a half life of 1.5 days (GEMS, 1984), and also of 17 hours using the TGD default OH radical concentration. The RAR uses the longer half life of 1.5 days in the EUSES calculations.
The AOPWIN model (v1.92) which forms part of EPI Suite, estimates a half-life of 11.616 hours. We have included this as a key study for this endpoint. However, since the TGD default OH radical concentration is the higher value, and we do not have access to the GEMS model, we use this value in this assessment.
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.
