Additional information

The test substance exhibits a low water solubility as defined by OECD Guidance No. 23 (less than 100 mg/L). The substance has to be considered as a difficult substance to be tested particularly for (i) achieving exposure concentration and (ii) preparing representative media.

The hydrolysis study was not conducted due to the low solubility of the test substance in water (< 0.2 mg/L). In a standard screening biodegradation test (CO2 evolution test), the percentage of biodegradation of test material was determined at 6% based on TCO2 after 28 days of exposure. The test substance does not meet the readily biodegradable criterion. A Koc value of 1.6*108 was predicted using a relevant QSAR. The test substance is thus likely to be immobile in soils.
