Description of key information
Log Kow (range; all constituents): >= 6.29 to <= 8.35 at 25 °C; ca. pH 7, QSAR Prediction - KOWWIN v1.68, Firmenich SA 2015
Key value for chemical safety assessment
Additional information
In accordance with REACH Regulation (EC) No. 1907/2006 Annex VII, column 2 section 7.8 the study does not need to be conducted if the test cannot be performed (e.g. the substance decomposes). A calculated value for log P is provided in conjunction to provided evidence of hydrolysis.
