Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

There are no experimental data on the potential adsorption to the solid soil phase of tert-butyl methacrylate. Based on an estimated Koc of 183.6 calculated by SRC KOCWIN v2.00 (corrected log Koc = 2.2645), adsorption to solid soil phase is not expected (BASF SE, 2021).
