Partition coefficient:
25 °C
Details on results:
Calculated by EPI (estimation program interface) Suite program with the model KowWin v.1.68 (for estimating log Kow).
The partition coefficient Log Kow was calculated as -3.86 by EPI Suite program (KowWin v.1.68).

Description of key information

The partition coefficient Log Kow was calculated as -3.86 by EPI Suite program (KowWin v.1.68).

Based on the structural similarity it can be concluded that the partition coefficient for EDTA-CoH2 is not significantly different.

Furthermore, the substance is produced in aqueous solutions and known to be highly soluble in water but to have a very low solubility in organic solvents as octanol. Thus the Log Kow value will be significantly below zero and bioaccumulative properties can be excluded.

Key value for chemical safety assessment

Log Kow (Log Pow):
at the temperature of:
25 °C
