Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The potential of the test material to undergo hydrolysis was investigated in accordance with the standardised guideline OECD 111 under GLP conditions.
The analytical method for determination of trace amounts of DMBPC in water was an HPLC gradient method which used a standard C18 reverse phase column, a water/acetonitrile gradient, and UV detection at 230 nm.
The hydrolysis in water was evaluated in a five day study at pH 4, 7 and 9 at 50 °C. The initial concentration of DMBPC was 345 µg/L. There was no loss of the test substance after 5 d. Therefore, no value could be determined for half-life.
DMBPC as a saturated solution in aqueous buffers at pH 4.0, 7.0 and 9.0 was found to be hydrolytically stable after 5.0 d at 50 °C. At pH 4, 7 and 9, the percent recovery values were 104.1, 103.5 and 100.2, respectively. Therefore, DMBPC is not amenable to abiotic degradation via hydrolysis (i.e., is stable in water).
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.
