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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
