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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
As the test item is miscible in any ratio in water and in n-octanol as well, the log Pow of the test item can not be estimated from the single solubilities in water and in n-octanol. The Pow of the test item cannot be determined according to the shake flask method (OECD Guideline for the Testing of Chemicals 107), because the test item is a multi-component mixture (for characterisation see GLP-study no. 14L00292) and due to the fact that the test item was not detectable in the n-octanol phases (during non-GLP GC measurements). It was also not possible to measure the water phases via GC. During the pre-test a formation of an emulsion in the n-octanol phase was observed. For this reason a measurement for the surface tension were done (OECD 115). Result: 68.89 mN/m. So the test item is not surface active. The determination of the log Pow was carried out according to the OECD Guideline for the Testing of Chemicals 117 (HPLC-method).
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.
