Key result

Water solubility:

> 49.4 other: w/w

Conc. based on:

test mat. (dissolved fraction)

Temp.:

20 °C

pH:

> 11.2 - <= 11.6

The standard EC A.6 / OECD 105 methodology was not applicable to this test item due to high solubility in water. Therefore, a range of sample concentrations ranging from 5 to 50 w/w were prepared for visual assessment.

All three samples were shaken by hand for 60 seconds prior to placing in the 20 °C water bath. At this stage, all three samples gave clear, single phase solutions, free from any visible excess test item.

The water solubility of the test item has been determined to be greater than 49.4 % w/w of solution at 20.0 ± 0.5 °C.

Sample	Concentration (% w/w)	Observations	Sample pH
1	4.8	Very pale yellow, clear, non-viscous, single phase solution below a significant quantity of foam/froth. No separated phases or any excess, undissolved test item.	11.2
2	25.2	As Sample 1, except pale yellow in color	11.5
3	49.4	Yellow, clear, viscous but mobile, single phase solution. No foam or froth present. No separated phases or any excess undissolved test item.	11.6

Conclusions:

The water solubility of the test item has been determined to be greater than 49.4 % w/w of solution at 20.0 ± 0.5 °C.

Executive summary:

Greater than 49.4 % w/w of solution, 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.
