Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Bioaccumulation factoropen allclose all
- Type:
- BCF
- Value:
- >= 5.8 - <= 32.1 L/kg
- Basis:
- whole body w.w.
- Remarks on result:
- other: BCFBAF regression-based estimate
- Type:
- BCF
- Value:
- >= 0.9 - <= 1.3 L/kg
- Basis:
- whole body w.w.
- Remarks on result:
- other: BCFBAF Arnot-Gobas (assuming a biotransformation rate of zero)
- Details on results:
- - In order of increasing molecular weight, the BCF’s of the constituents are calculated to be 32.1, 20.9, 13.6, 8.9 and 5.8 (BCFBAF regression-based estimate)
- In order of increasing molecular weight, the BCF’s of the constituents are calculated to be 1.3, 1.1, 0.96, 0.92 and 0.90 (BCFBAF Arnot-Gobas, assuming a biotransformation rate of zero)
Applicant's summary and conclusion
- Conclusions:
- Calculated BCF values for the constituents are low (0.9 - 32.1 L/kg).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
