Results and discussion

Water solubility
Water solubility:
24 mg/L
Temp.:
20 °C
pH:
7.8

Any other information on results incl. tables

The solution (100 mg/L test item was weighed out) was prepared with dilution water one day prior to application.

The stock solution was shaken at room temperature with 20 rpm for 24 h (rotating shaker 3040, GFL) and membrane filtrated with 0.45 urn (RC, Schleicher & Schuell).

Test dilutions of the saturated solutions: 1:160-1:80- 1:40 - 1:20- 1:10

Real test concentrations (calculated from carbon content analysis): 0.15 - 0.30 - 0.61 - 1.21 - 2.42 mg/L

From this data the solubility of the test item can be calculated as 24 mg/L

Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information): slightly soluble (0.1-100 mg/L)
