Applicant's summary and conclusion
- Conclusions:
- Interpretation of results: moderately soluble (100-1000 mg/L)
The water solubility of the test item has been determined to be 0.375 g/L of solution at 20.0 ± 0.5 °C (with respect to the C12-14 alkylamine species) and 0.439 g/L of solution at 20.0 ± 0.5 °C (with respect to the isooctyl phosphate species) (as test item equivalents). - Executive summary:
The water solubility of the test item was 0.375 g/L of solution at 20.0 ± 0.5 °C (with respect to the C12-14 alkylamine species) and 0.439 g/L of solution at 20.0 ± 0.5 °C (with respect to the isooctyl phosphate species) (as test item equivalents), using the flask method, designed to be compatible with Method A6 Water Solubility of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 105 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.
