Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Results and discussion

Percent distribution in media

Air (%):
11.5
Water (%):
88.5

Any other information on results incl. tables

Over time, the substance will preferentially distribute into water.

Applicant's summary and conclusion

Conclusions:
In air DMF shows a distribution level of 11.5 % and in water 88.5 %. Based on the calculation it is not expected to appear in soil, sediments and biota.
Executive summary:

Over time, the substance will preferentially distribute into water (88.5 %). For the remaining 11.5 % the air compartment will be the relevant sink.
