<10 μg/L at 23°C

Key value for chemical safety assessment

Additional information

The solubility was analysed by photometric method after dissolution of the pigments in 8% and 95% ethanol in water.

The results reported refer to the three batches of the test item.

The test item is insoluble in 8% ethanol (detection limit: 10 μg/L). In 95% ethanol the three batches of the test item showed a solubility of 145 μg/l, 203 μg/l and 106 μg/l, respectively.

It can be concluded that the solubility of test item in pure water is less than the solubility with 8% ethanol (aqueous)
