Because of the chemical nature of the test item it was not possible to adjust a suitable instrumental analytical method to investigate a more precise value, the test item water solubility was fixed as lower than 0.1 g/L.
Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information): moderately soluble (100-1000 mg/L)
From the obtained experimental data according to CIPAC method MT 157, A.6 method in Council Regulation (EC) No 440/2008 of 30 May 2008 and OECD guideline No. 105, it can be concluded that the water solubility of Soybean (Glycine max) dry purified extract sample is lower then 0.1 g/L at 20°C.
