Conclusions:

Interpretation of results: insoluble (< 0.1 mg/L)
The solubility of the MELON 1 ,3,5-Triazine-2,4,6-triamine, deammonated in water was determined from the measured concentrations of organic carbon in the filtrated test solutions.

Equilibration time can be considered as approx. 2 days, as the values which were measured on the following consecutive days did not give significantly different values.

At the plateau, the concentration of MELON 1,3,5-Triazine-2,4,6-triamine, deammonated in water had reached

3.39 ±0.47 mg/L at 20 °C = 3.39 ± 0.47 * 10-3 kg/m3 (SI units)

(mean value ± standard deviation of six individual values of vessel 1-3) for the following nominal concentration of the test item in water: 10 g/L.

For the nominal concentration of the test item in water 1 g/L (flasks 4 - 6), no solubility in water could be determined, as the measured values lay below the LOQ of the carbon analyser.

Executive summary:

The solubility of the MELON 1 ,3,5-Triazine-2,4,6-triamine, deammonated in water was determined from the measured concentrations of organic carbon in the filtrated test solutions (The test item was insoluble in all tested solvents, such as acetonitrile, methanol and formic acid.).

Equilibration time can be considered as approx. 2 days, as the values which were measured on the following consecutive days did not give significantly different values. At the plateau, the concentration of MELON 1,3,5-Triazine-2,4,6-triamine, deammonated in water had reached 3.39 ±0.47 mg/L at 20 °C = 3.39 ± 0.47 * 10-3 kg/m3 (SI units) (mean value ± standard deviation of six individual values of vessel 1-3) for the following nominal concentration of the test item in water: 10 g/L. For the nominal concentration of the test item in water 1 g/L (flasks 4 - 6), no solubility in water could be determined, as the measured values lay below the LOQ of the carbon analyser.

Description of key information

For the nominal concentration of the test item in water 1 g/L (flasks 4 - 6), no solubility in water could be determined, as the measured values lay below the LOQ of the carbon analyser.
