Specific details on test material used for the study:

Name (as stated in the report): Velvione
Batch: VE00413992
Expiration date: January 01, 2017

Key result

Water solubility:

0.65 mg/L

Conc. based on:

test mat.

Temp.:

20 °C

pH:

>= 6.3 - <= 6.4

Details on results:

At test end the pH values of the solutions in ultrapure water were pH 6.3, pH 6.4 on two independent flasks.

Conclusions:

The test shows that there is no significant change of the measured concentrations after 288 h, 312 h and 336 h. Thus it can be concluded that equilibrium is reached. Thus the results obtained after 288 h, 312 h and 336 h were averaged, to give the water solubility of Velvione. After rounding off: Solubility of Velvione in water at 20°C: 0.65 mg/l

Executive summary:

The solubility of Velvione in ultrapure water was determined according to the OECD Guideline No. 105 (flask method).

The result is: Solubility in water: 0.65 mg/l at 20°C

 This result corresponds to the saturation mass concentrations of Velvione in ultrapure water at 20°C.
