Reference
Final Result
The HPLC method revealed a n-octanol/water partition coefficient (log Pow) for the test substance:
log Pow (Perlastan C-30) = -1.3 (at 23±1 °C)
The worst case log Pow calculated from the retention time of the peak cut-off was 4.8. The averaged log Pow including the retention time from the start to the peak cut-off was not computable.
Individual results
The test results displayed an average log Pow of -1.3±0.0.

start cut-off peak
n.c. 4.8 -1.3
n.c. 4.8 -1.3
n.c. 4.8 -1.3
n.c. = not computable
It was not possible to calculate a weighted average since the single peaks of Perlastan C-30 components could not be distinguished.

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.
