Description of key information
In accordance with Section 2 of Annex XI of Regulation (EC) 1907/2006 (REACH), it is considered justified to omit the test for water solubility (required under point 7.7 of Annex VII) as it is considered that testing is not technically possible.
The determination was attempted using a flask method based on the standardised guidelines OECD 105 and EU Method A.6.
Sample solutions saturated in the range of 0.11 to 9.43 % w/w resulted in the formation of stable dispersions at 20.0 ± 0.5 °C. As this suspended, excess, undissolved test material could not be removed by either centrifugation or filtration techniques, it was not possible to isolate clear, saturated sample solutions suitable for analysis. Therefore no experimental determination of water solubility was possible.
The observed behaviour in water was consistent with the proposed composition and the low surface tension values determined, 44.0 to 44.4 mN/m.
As the salt interaction with the potassium counter ions was beyond the scope of available prediction methods (computer software and/or QSAR methods), no alternative estimation of the water solubility was possible.
Key value for chemical safety assessment
