Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

At environmentally relevant pH and 25°C the logKoc of MBS is determined as 2.84. Due to hydrolysis, the adsorption coefficients of the degradation products (e. g. MBT, BT and morpholine) are relevant for risk assessment of MBS in the environment. MBT and BT have a moderate adsorption potential in soil/sediment with the adsorption coefficient (log Koc) of 2.51 – 3.55 and 3.0, respectively. Morpholine however has only a low affinity to adsorption with a logKoc of 0.867. MBS is essentially non-volatile with the calculated Henry's law constant lower than 5.52*10-7 Pa m3/mol at 25°C. The distribution of MBS in a "unit world" was calculated according to the Mackay fugacity model level I based on the physico-chemical properties. The main target compartment for MBS is water of 71.3 % and sediment of 14.32 %, followed by soil of 14.16 %.
