Description of key information

The adsorption/desorption coefficient of the individual relevant main constituents of the test substance (BPA ethoxylated mono- and dimethacrylates, 2 to 4 mol EO) was estimated using the recommended QSAR model KOCWIN v2.00, via the MCI method.


The estimated Koc values were in the 1358 to 3812 L/kg range and the log Koc was between 3.13 and 3.58. As a conservative approach, the highest value (log Koc = 3.58; Koc = 3812 L/kg) was selected for the chemical safety assessment.
