Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information): moderately soluble (100-1000 mg/L)The water solubility of (-)-α-pinene oxide was determined to be about 366 mg/L at 25 oC.
- Executive summary:
In a non-guideline study, the water solubility of (-)-α-pinene oxide [alpha pinene epoxide laevo] was determined to be 2.55 +/- 0.48 mmol/L (about 366 mg/L) at 25 oC, which is considered moderately soluble.
