Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Partition coefficient
Administrative data
Link to relevant study record(s)
- Endpoint:
- partition coefficient
- Data waiving:
- study technically not feasible
- Justification for data waiving:
- the study does not need to be conducted because the substance decomposes
Reference
Description of key information
The test item is hydrolytically not stable at pH 4, 7 and 9. Therefore, no test on partition coefficient is needed.
Key value for chemical safety assessment
- Log Kow (Log Pow):
- -0.57
- at the temperature of:
- 25 °C
Additional information
In accordance with column 2 of REACH Annex VII, the partition coefficinet study does not need to be conducted as the substance is hydrolytically unstable at pH 4, 7 and 9 at 12 °C (half-life less than 12 hours). The half-life of the test item in water was determined to be <3 h (refer to IUCLID Section 5.2.1).
Additionally, a QSAR estimation of the log Pow of the test item was calculated with EpiSuite v4.11. Using KOWWIN v1.68 the log Pow of the test item was calculated to be -0.57 at 25 °C.
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.
