Description of key information
Estimated log Pow= 10.5
Key value for chemical safety assessment
Additional information
The substance is surface active therefore the study does not need to be conducted. A calculated value for logP as well as details of the calculation method shall be provided according to column 2 of Annex VII of REACH Regulation (EC) No 1907/2006.
The represented log Pow value was estimated based on fragment method according to Hansch and Leo (1989).
An additional re-calculation (2020) using KOWWIN module of software EPI Suite yielded a log Pow value of 10.2. The molecular weight of the substance is within range of training and validation set. The substance is within the applicability domain of the model.
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.
