Bonite is insoluble in water.
Executive summary:

Aluminium: The concentrations decreased from day 1 to 2 at the test with the loading rate ~1000 mg/L and were constant during the test with the loading rate ~100 mg/L. The difference between the concentrations of aluminium of day 1 to 2 at the test with the loading rate ~1000 mg/L was >15 %. The difference between the concentrations of aluminium of day 1 to 3 at the test with the loading rate ~100 mg/L was < 15%. Therefore the maximum of day 1 respectively the mean of day 1 - 3 was taken as the solubility of the test substance at 20 °C, according to the guidelines. The water solubility of aluminium as part of "Dodecaaluminium calcium nonadecaoxide, AL12O19Ca (Calciumhexaluminate, CA6)" at 20.0 °C was determined to: Mean: 0.0046 mg/L, standard deviation: 0.00037, replicates of three days, loading rate ~100 mg/L.

Maximum: 0.034 mg/L, loading rate ~1000 mg/L.

The test substance contains 48.2 % Al, according to the Certificate of Analysis. The "water solubility of test substance equivalents", calculated from the Al-concentration at 20 °C, is therefore

0.0095 mg/L (loading rate ~100 mg/L) respectively

0.071 mg/L (loading rate ~1000 mg/L)

Calcium: The concentrations increased from day 1 to 2 and were constant afterwards at both tests. The difference between the concentrations of aluminium of day 2 to 3 was taken as the solubility of the test substance at 20 °C, according to the guidelines.

The water solubility of magnesium as part of "XXX" at 20.0 °C was determined to:

Mean: 0.030 mg/L, standard deviation: 0, replicates of two days, loading rate ~100 mg/L.

Mean: 0.075 mg/L, standard deviation: 0, replicates of two days, loading rate ~1000 mg/L.

The test substance contains 5.3 % Ca, according to the Certificate of Analysis. The "water solubility of test substance equivalents", calculated from the Ca-concentration at 20 °C, is therefore

5.7 mg/L (loading rate ~100 mg/L) respectively

14.2 mg/L (loading rate ~1000 mg/L).

The lowest calculated "water solubility of test substance equivalents" is 0.01 mg/L, which represents therefore the highest possible water solubility of the undissociated test substance.
