Additional information
A weight of evidence approach was taken when assessing the octanol/water partition coefficient of the substance. The data used to fulfil this data requirement were all sourced from the following peer reviewed handbooks:
Verschueren, K (2001) Handbook of Environmental Data on Organic Chemicals (4th Edition)
Gangolli, S. ed. (2005) Dictionary of Substances and Their Effects (DOSE, 3rd Electronic Edition)
The data were all in agreement. All were assigned a reliability score of 2.
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.
