Results and discussion

Water solubility
Remarks on result:
other: The test item is miscible with water at room temperature (T = 23°C) and atl T = 20.0°C ± 0.5°C in any ratio.

Any other information on results incl. tables

Analytical Method:

The test item and water were mixed in three different ratios (1 :9, 1: 1, 9: 1) to cover the range of complete miscibility.

The mixtures were shortly shaken by hand at T = 23"C (see observation) and after that conditioned overnight at 20.0°C ± 0.5°C.

The following mixtures were prepared:

After conditioning overnight at 20.0°C ± O.5°C, no changes were observed.

The test item is miscible with water at room temperature (T = 23°C) and atl T = 20.0°C ± 0.5°C in any ratio.
