Other sulfated oils have been tested for this endpoint and the partition coefficient has been found to range from 0.43 to 1.20. See section 13 (Report on similarity) for more details.

Conclusions:
Log Pow has been determined to be 0.87 for the substance.
Executive summary:

The Partition coefficient has been evaluated using a method based on OECD TG 107.

Log Pow was determined to be 0.87 for the substance and within the range 0,43-1,20 for the tested representative samples of sulfated oils.

Description of key information

Log Pow = 0.79 for the substance.

Log Pow =[0,43;1,20] for sulfated oils representative samples.

Additional information

The Partition coefficient has been evaluated according to OECD TG 107.

Log Pow was determined to be .79 for the substance and within the range 0,43 -1,20 for the other tested representative samples of sulfated oils.

In particular, the following has been found:

- average value: log Pow = 0.71

- Oils, vegetable, sulfated, sodium salts (main representative): log Pow = 0.59

- Oils, fish, sulfated, sodium salts (representative): log Pow = 0.70

- Oils, vegetable, sulfated, ammonium salts (representative): log Pow = 0.87

- Castor oil, sulfated, sodium salt (representative): log Pow = 0.54
