Description of key information

<0.0005 g/L at 20°C
(at 574 nm; main components)

Key value for chemical safety assessment

Additional information

The test substance is a mixture of approx. 6 major components and several traces.The water solubility of the main components as a mixture of chronium complexes was determined to be <0.0005 g/L at 574nm at 20°C using a spectrophotometeric method. Because the test substance is a mixture of several components, each having its own solubility, no exact value can be given.

The solubility of test substance in water was determined to be relatively low. Based on the absorbance at 226 nm and 574 nm, a water solubility of 0.023 g/L and < 0.0005 g/L, respectively, at 20 ± 1.0°C was obtained.
