Description of key information
Using the OECD 117 HPLC method, the partition coefficient of the test substance was determined. Due to the highly complex nature of the UVCB substance, a number of peaks were observed in the chromatogram, each of which appears to be a cluster of multiple peaks. There was a major cluster of peak area 76.9% of the total, and four other in the range 9 -2%. Each cluster provided different logPow values, shown below.
Cluster 1 (76.9%) - 0.14 -3.9
Cluster 2 (9.2%) - 4.1
Cluster 3 (7.9%) - 4.4 -4.7
Cluster 4 (4.9%) - 5.0 -5.4
Cluster 5 (2.2%) - 5.5 -6.3
Key value for chemical safety assessment
Additional information
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.
