Applicant's summary and conclusion

Executive summary:

The constituents of JASMONYL LG can be grouped in acetylated compounds (about 95 % of the test item), and non-acetylated compounds (about 5 % of the test item).

Based on these data, two loading rates were applied.

For a JASMONYL LG low loading rate (>2.5 g/L), the water solubility at 20 °C was found to be 661 ± 16 mg/L.

For a JASMONYL LG high loading rate (>25 g/L), the water solubility at 20 °C was found to be 1081 ± 13 mg/L.

The test item is a mixture of several constituents with different solubilities. As it can not be excluded that the different constituents influence the other constituents’s solubilities, the results should be regarded as approximated values.
