Additional information
Hydrolysis:
The test on the hydrolysis of FAT 41043/A TE as a function of pH of the test substance could not be performed since it was not possible to accurately monitor the degradation rate of the test substance at initial concentrations of approximately 10 ng/l (half the water solubility).
Biodegradation:
NOTOX study Nr. 498117:
FAT 41043/A TE was not readily biodegradable under the conditions of the 'Manometric Respirometry Test.
NOTOX study Nr. 497918:
Due to the physical chemical properties of FAT 41043/A TE, especially the limited solubility in water, performance of a Zahn-Wellens/EMPA test was not possible.
NOTOX study Nr. 498116: According to the general principle of the BOD5 test a solution of FAT 41043/A TE of at least 2 mg/l in mineral medium should be inoculated and incubated under aerobic conditions in the dark or in diffuse light. Due to the physical chemical properties of FAT 41043/A TE, especially the limited solubility in water, performance of a BOD5 test was not possible. Therefore, it is not possible to perform the BOD5 test (EEC Directive 440/2008, Part C.5. 2008; ISO Standard 5815, 2003).
Adsorption: The Koc of FAT 41043/A TE was determined to be 2.6 x 10^6 (log Koc= 6.42) by the HPLC estimation method (EC C.19 and OECD 121).
