Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In water, BPA-DA is not stable and hydrolyses quickly to form 4,4'-Bisphenol ATetra Acid (BPA-TA). BPA-TA is not sensitive to hydrolysis. Biotic degradation data show that no ultimate breakdown of BPA-DA occurs (i.e., no full mineralisation).
The relevant substance for the aquatic environment is thus BPA-TA and hence aquatic effects studies are performed on this primary hydrolysis product.
In air, a half-life of 8.062 h (at 12 -hour daylight) is calculated for BPA-DA based on reaction with hydroxyl radicals.
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.
