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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Distribution modelling
Administrative data
- Endpoint:
- distribution modelling
- Type of information:
- migrated information: read-across based on grouping of substances (category approach)
- Adequacy of study:
- supporting study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Although not a SIDS end point, this study is considered to be the best study of Koc for these carbon numbers.

Results and discussion
Any other information on results incl. tables
Alcohol sorption coefficients showed some time dependence, reaching a plateau by 72 h. C15 was found to be an unexplained outlier. The 72 h
results were:
C 12 14 15 16 18
Kd 3000± 8490± 3080± 23800 78700
80 920 270 ±3200 ±5400
Koc 17980 50830 - 143000 471000
log Koc 4.25 4.71 - 5.15 5.67
These data (neglecting the C15) can be interpreted as a QSAR in the usual way as:
Log Koc = 0.11 + 0.77 log Kow
R2 = 0.994
The result is in line with typical QSARs of this type.
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
