Description of key information

LC50 (96h) > 1.23 mg/L, which constitutes the limit of solubility of the test item under the test conditions

Key value for chemical safety assessment

Additional information

Isononyl benzoate was tested in acute toxicity with Cyprinus carpio under semi-static conditions according to the guidelines EEC specification 92/69/EEC (C.1) and OECD 203. The test was conductet as limit test. In order to attain the solubility limit of the test substance, which is poorly soluble in water, 1g benzoesäure-isononylester/ l was stirred for 18 h and undissolved test substance was then removed by filtration. A loss of test substance over the test period was recorded by measurement of dissolved organic carbon, the concentration values given are therefore mean measured values. No effects on the exposured carps were recorded, thus the LC50 > 1.23 mg/l which constitutes the solubility limit of the test substance under the conditions of the test.
