Results of the HPLC Method
In the chromatograms of the test item solution, several peaks with retention times of 31.0 – 32.2 minutes were observed. Under the same analytical conditions, the retention time of benzo[ghi]perylene (log Pow = 7.2) was 19.1 minutes. It was concluded that the log Pow of test item was > 7.2 (Pow > 1.6 x 107).
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.
