Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Applicant's summary and conclusion

Conclusions:
Assuming as a most likely case a 100% release of MMB to water, the McKay Level III calculation predicts 10.1% emitted to air and 0.4 % remaining in the sediment. The model does not predict any emissons to soil.
