Results and discussion
Water solubility
- Water solubility:
- 0.009 g/L
- Temp.:
- 20 °C
- Remarks on result:
- other: The test item significantly degraded/hydrolyzed in water with increased initial saturation/exposure period leading to accumulation of hydrolysis/degradation products and a decrease in the contribution of the parent to the total sample response.
- Details on results:
- The water solubility of the parent test item has been determined to be 8.72 x 10-3 g/L of solution at 20.0 ± 0.5 °C. However, the test item was identified to degrade/hydrolyze in the presence of water, with an increased initial saturation/exposure period leading to an accumulation of hydrolysis/degradation products and a decrease in the contribution of the parent test item to the total sample response on analysis.
On analysis of the short-term evaluation of water solubility sample prepared during preliminary testing, evidence of hydrolysis/degradation was still evident even after reducing saturation and re-equilibration periods to only one hour each.

Applicant's summary and conclusion
- Conclusions:
- The water solubility of Linalyl propionate was 8.72 x 10-3 g/L of solution for the parent test item at 20.0 ± 0.5 °C.
- Executive summary:
The water solubility of Linalyl propionate was measured according to OECD Guideline No. 105 (flask method).
The water solubility of Linalyl propionate was 8.72 x 10-3 g/L of solution for the parent test item at 20.0 ± 0.5 °C.
