Applicant's summary and conclusion
- Conclusions:
- Partition coefficient n-octanol / water (Kow) at 25 °C: Kow = 1.0 x 10^5 - 1.58 x 10^5
log Kow = 5.0 - 5. 2 - Executive summary:
The partition coefficient n-octanol / water (Kow) of the test item was determined according to OECD guideline no. 117 [adopted on 13 April 2004] and EU test method A.8 [Council Regulation (EC) No 440/2008 of 30 May 2008] with the HPLC method. Partition coefficient n-octanol / water (Kow) at 25 °C: Kow = 1.0 x 10^5 - 1.58 x 10^5
log Kow = 5.0 - 5. 2
