Data platform availability banner - registered substances factsheets

Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Diss Factsheets

Administrative data

Endpoint:
distribution modelling
Type of information:
calculation (if not (Q)SAR)
Remarks:
Migrated phrase: estimated by calculation
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Absence of the QMFR format, but in the software is used and approved by most regulatory programs and applicability domain is respected

Applicant's summary and conclusion

Conclusions:
The environmental compartment more involved is sediment, followed by water and soil in very low percentage, and air is almost absent
Executive summary:

Distribution modelling has been performed with the Level III fugacity model of EPISUITE 4.0
