- ca. 0.46 dimensionless
Any other information on results incl. tables
The KOCvalue calculated from the octanol-water partition coefficient (log Kow = -1.07) using the equation from the TGD (non-hydrophobics) is 2.9 (log value = 0.46). This predicted value is used in the assessment.

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.
