Conclusions:

The study was performed according to OECD TG 105 under GLP on the substance to be registered itself, the test procedure is well documented and therefore reliability of Klimisch 1 has been assigned. The analytical method was properly established. The limit of quantification (LOQ) was assessed at a test item concentration of 10 µg/L in water. The response of the test samples was lower than the response of the lowest calibration solution (0.450 µg/L). The analyzed concentration in the test samples was determined to be < 4.5 µg/L taking a dilution factor of 10 into account. In conclusion it can only be stated that the water solubility of the test item at 20°C was < 4.5 * 10E-6 g/L, making a quantification in e.g. ecotoxicity test impossible as the test item must be regarded as practically insoluble in water.

Executive summary:

The water solubility of the test item was determined according to EC A.6, OECD 105, and OPPTS 830.7840 under GLP at 20°C by the slow-stirring flask method as < 4.5 x 10E-6 g/L.

Description of key information

Water solubility: < 4.5 x E-6 g/L at 20°C (EC A.6, OECD 105, OPPTS 830.7840, GLP, slow-stirring flask method)

Key value for chemical safety assessment

Water solubility:

0 g/L

at the temperature of:

20 °C

Additional information
