Description of key information
Koc < 9.1 and logKoc < 0.97. Results could not be accurately determined due to the low retention time of the substance. EU Method C.19, OECD 121, Szabo (2013).
Data is read-across from the similar substance Reaction mass of sodium hydrogen N-(1-oxooctadecyl) -L-glutamate and sodium hydrogen n-(1-oxohexadecyl) -L-glutamate.
Key value for chemical safety assessment
- Koc at 20 °C:
- 9.1
Additional information
In the key study (Szabo 2013, read-across from the similar substance Reaction mass of sodium hydrogen N-(1-oxooctadecyl) -L-glutamate and sodium hydrogen n-(1 -oxohexadecyl) -L-glutamate) the adsorption coefficient of the test material was investigated using the HPLC method in accordance with the standardised guidelines OECD 121 and EU Method C.19. The study was performed under GLP conditions. The study was therefore assigned a reliability score of 1 in accordance with the principles for assessing data quality as defined in Klimisch et al. (1997).
The study was carried out using an HPLC system with UV detection. The mobile phase was acetonitrile:buffer (pH 5.4) 6:4. The reference substances used to create the calibration curve were Sodium nitrate, Acetanilide, Methyl benzoate, Triazophos, Naphthalene, Fenthion and α-Endosulfan.
Under the conditions of the test, the test material eluted with a retention time of 1.57 minutes. This was less than the retention time of the first reference substance. Therefore calculation of the logKoc and Koc was not possible.
An accurate adsorption coefficient could not be determined, however it was concluded that the logKoc and Koc are lower than 0.97 and 9.1, respectively (the logKoc and Koc of the first reference substance).
[LogKoc: 0.97]
