The performance of the test to assess the partition coefficient n-octanol/water is scientifically unjustified.REACH Regulation (EC) No 1907/2006, Annex VII, Sect. 7.8., Col. 2, states as follows:"7.8. The study does not need to be conducted if the substance is inorganic. If the test cannot be performed (e.g. the substance decomposes, has a high surface activity, reacts violently during the performance of the test or does not dissolve in water or in octanol, or it is not possible to obtain a sufficiently pure substance), a calculated value for log P as well as details of the calculation method shall be provided."Due to rapid hydrolysis of the test substance upon contact with water, measurement of the partition coefficient of the test substance was technically not feasible. The log Kow of the test substance was calculated to be 6.8532 (KOWWIN Program (v1.68)). This calculated value was used for chemical safety assessment purposes.
