Propylidynetrimethanol, ethoxylated, propoxylated, esters with acrylic acid (<6.5 mol EO and <6.5 mol PO)

Partition coefficient

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 P_ow values in the range from log P_ow -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 P_ow 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 P_ow = -0.3 (extrapolated)

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

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

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

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

End of the distribution: log P_ow = 5.6
