Description of key information

The test item consists of a mixture of compounds with different degrees of ethoxylation and propoxylation. The determination according to the HPLC method (OECD 117) yielded log Pow values in the range from log Pow -0.3 to 5.6 at T = 23 °C and pH = 6.4 (pH of the water used for the preparation of the eluent)

Key value for chemical safety assessment

Log Kow (Log Pow):
4.2
at the temperature of:
23 °C

Additional information

A GLP study was conducted in accordance with the OECD Guideline for the Testing of Chemicals 117 (HPLC method). The test item consists of a mixture of compounds with different degrees of ethoxylation and propoxylation. The determination according to the HPLC method (OECD 117) yielded log Pow values in the range from log Paw -0.3 to 5.6 at T = 23 °C and pH = 6.4 (pH of the water used for the preparation of the eluent).

Start of the distribution: log Pow = -0.3 (extrapolated)

Main component 1: log Pow = 2.4 (7.1 area-%*)

Main component 2: log Pow = 4.1 (9.8 area-%*)

Main component 3: log Pow = 4.2 (24.0 area-%*)

Main component 4: log Pow = 4.7 (12.8 area-%*)

End of the distribution: log Pow = 5.6
