Endpoint:
water solubility
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Qualifier:
according to
Guideline:
EU Method A.6 (Water Solubility)
Version / remarks:
The determination was carried out by visual assessment, using a modified flask method designed to be compatible with Method A.6 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.
Deviations:
no
Principles of method if other than guideline:
The standard EC A.6/OECD 105 methodology was considered not applicable to this test item due to the expected high saturation level. Therefore, a range of sample concentrations were prepared to visually assess the point at which saturation was reached.
Mixtures of test item and purified water in different ratios were added to the separate flasks. After preparation, the samples were shaken (200 rpm) at 30.0 ± 1.0 °C for 24¼ hours followed by static equilibration at 20.0 ± 0.5 °C for a period of 24 hours and then the contents of the flasks were visually assessed.
GLP compliance:
yes (incl. certificate)

Conclusions:
The water solubility of the test item has been determined to be in the range of 79.9 to 82.0% w/w at 20.0 ± 0.5 °C which corresponds to 657.1-660.5 g/l.
Executive summary:

The water solubility of the test item has been determined to be in the range of 79.9 to 82.0% w/w at 20.0 ± 0.5 °C which corresponds to 657.1-660.5 g/l.
