Specific details on test material used for the study:
Ester B is a white solid wax, to test its solubility it was pulverized.
Water solubility:
0.37 other:
Conc. based on:
test mat. (dissolved fraction)
Incubation duration:
3 d
Temp.:
20 °C
pH:
ca. 6.2
Remarks on result:
other: average of three determination
Details on results:
Preliminary test:
Tested samples powder white particles are clearly visible in 2 litre beaker (capped during test), also after 96 h under continuously stirring at 30 °C.
The difference was found to be less than 15%, therefore, the test is satisfactory.
Considering tests 7, 8 and 9, the average final solubility of Ester B was found to be 0.37 mg/L.
Conclusions:
Water solubility: 0.37 mg/L at 20 °C and pH 6.2.
Executive summary:

The water solubility of Ester B was evaluated in a preliminary test and a final test. Considering tests 7, 8 and 9, the average final solubility of Ester B was found to be 0.37 mg/L.
