*pH paper

** Limit of quantification for DINCD: 25 µg/L

Conclusions:
The water solubility of the test item was determined according to the slow-stir method as described in the following documents:
• European Chemicals Agency (ECHA), Guidance on information requirements and chemical safety assessment, chapter R. 7 A - endpoint specific guidance, May 2008.
• Letinski, D.J. et al. (2002), Slow-stir water solubility measurements of selected alcohols and diesters, Chemosphere 48, 257-265.
Water solubility (at room temperature): < 25 µg/ L

Description of key information

The water solubility of the test substance has been determined to be below 25 µg/L by a slow-stirring method.

Key value for chemical safety assessment

Water solubility:
25 µg/L

Additional information

The water solubility of the test item has been determined according to the slow-stir method as described in the ECHA guidance document Chapter R.7a (May 2008) and by Letinski et al. (2002). The water solubility of the test substance has been found to be below 25 µg/L.
