Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Data availability:

There are estimated BCF data available but no test data.According to REACH regulation, annex IX, paragraph 9.3.2, column 2, a fish bioconcentration test does not need to be conducted if "the substance has a low potential for bioaccumulation (for instance a log Kow < 3)".

BCF estimate

For i-BMA, the logKow is estimated to be 2.95 according to best studies. Based on that a BCF of 64 has been predicted according to the formula of Veith et al. (1979).

In addition, it has been shown that i-BMA is readily biodegradable without lag phase, indicating that metabolism does not generally need adaptation. Mammalian metabolism data indicate rapid metabolism and a ubiquitous pathway. Therefore, the substance has a low bioaccumulation potential and it is not justified to carry out a fish bioconcentration study.
