- Key result
- Type:
- log Pow
- Partition coefficient:
- 0.87
- Temp.:
- 20 °C
- pH:
- ca. 6.7
- 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.
Reference
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.
Description of key information
Log Pow = 0.87 for the substance.
Log Pow =[0,43;1,20] for sulfated oils representative samples.
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 0.87
- at the temperature of:
- 20 °C
Additional information
The Partition coefficient has been evaluated according to OECD TG 107.
Log Pow was determined to be .87 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: Pow = 0.71
- Oils, vegetable, sulfated, sodium salts (representative): Pow = 0.59
- Oils, fish, sulfated, sodium salts (representative): Pow = 0.70
- Castor oil, sulfated, sodium salt (representative): Pow = 0.54
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
