Applicant's summary and conclusion

Executive summary:

An experimental determination of the partition coefficient n-octanol/water was not possible, as the

described method (European Commission Regulation No. 440/2008, A.8. and OEGD test guidelines

107 and 117) is not suitable for surface active substances and for strong acids.

The program kowwinnt (part of episuite, v3.20) was used for calculating the log Pow of the test item.

The calculated value of the partition coefficient Pow of the test item was: 8.3.
