Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information): soluble (1000-10000 mg/L)
Solubility of 2Coumaranone is found to be 3.8 g/l at 30°C. - Executive summary:
Solubility of 2Coumaranone is found to be 3.8 g/l at 30°C; study according to Method A6 Reg. 440/2008 with low stirring time (10min) due to unstability of the substance in water (see Hydrolysis § 5.1.2)
