Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Read across: An experimental study on the structural analogue 2-ethylhexyl methacrylate (log Kow > 4) (Schäfers, 2006) of bioconcentration of the substance, according to OECD guideline 305 demonstrates that a rapid metabolism occurs, this depuration prevents any significant accumulation (BCF = 37).

Key value for chemical safety assessment

BCF (aquatic species):
37

Additional information

The octanol/water partition coefficient of the substances, log Kow > 4, predicts a potential for bioaccumulation.

Simple models linking BCF to log Kow would give BCF in the range of about > 1000 depending on the model and the log Kow used .

On the contrary, an experimental study (Fraunhofer, 2006) has been carried out on the structural analogue 2-ethyl hexyl methacrylate (log Kow > 4) to assess the fish bioconcentration of the substance, according to OECD guideline 305. This study demonstrates that a rapid metabolism occurs, and this depuration prevents any significant accumulation (BCF = 37).
