Description of key information
A log Koc of 1.06 (11.4 L/kg) can be taken as representative for EEA-NH4.
Key value for chemical safety assessment
- Koc at 20 °C:
- 11.4
Additional information
A GLP-compliant OECD guideline 121 study is available (TNO Quality of Life, 2008b). Two test were performed, in the first test methanol/water 55/45 v/v % was used and during the second test a methanol/water 55/45 v/v % mixture made up to pH 5.5 with formic acid and ammonium formiate was applied. Under both conditions the log Koc of the EEA ion of EEA-NH4 could not be determined, because the negatively charged EEA ion exhibited a peak in the chromatogram with retention time lower than t0. Therefore, the organic carbon-water partitioning coefficient (Koc) was calculated from the octanol-water partition coefficient (log Kow) using the equation from EUSES (predominantly hydrophobics). The calculated log Koc is 11.4 L/kg (log value = 1.06) from a log Kow of 1.18. This predicted value is used in the assessment.
