Results and discussion
Partition coefficient
- Type:
- log Pow
- Partition coefficient:
- >= 7.4 - <= 8.5
- Temp.:
- 20 °C
- pH:
- 7.5
- Remarks on result:
- other: The test substance showed a retention time higher than those of the reference substances.
- Remarks:
- It was not possible to give a Log Pow result on the test item. In the more concentrated solution, the chromatogram showed a band that start at 25 minutes and end at 55 minutes, corresponding to a Log Pow interval ranging from 7.4 to 8.5.

The calibration reference standards consist of 6 reference substances of known log POW: Ethyl benzoate, Phenyl benzoate, Benzyl benzoate, Dibenzyl, Triphenylamine and 4.4-DDT. The standards chosen had a log POW between 2.6 and 6.5.
It was not possible to give a Log POW result on the test item.
In the more concentrated solution, the chromatogram showed a band that start at 25 minutes and end at 55 minutes, corresponding to a Log POW interval ranging from 7.4 to 8.5.
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.
