- Executive summary:
In the non GLP Klimisch 1 key study from Frischmann (2012), the water solubility Sodium di(1.3-dimethylbutyl) sulfosuccinate
was determined according to OECD 105 and EU method A.6. Gel formation was observed at concentrations > 500 g/L. The water solubility was determined to be > 500 g/L at 20°C.
The results of this study are considered relevant and reliable for the risk assessment.
Reference
In a preliminary test, the following aliquots of Sodium di(1.3-dimethylbutyl) sulfosuccinate were added to 2 g of water and stirred slowly for tem minutes.

With 3 g test item being added to 2 g water a gel with approximately 5 g was formed. This is equivalent to 60% (w/w) of the test item in the gel. As the density of the solution/gel increased it can be concluded that the water solubility is about 600 g/L in the gel. Since gel formation is a continuous process, the water solubility is reported as > 500 g/L.
Description of key information
Water solubility: > 500 g/L
Key value for chemical safety assessment
- Water solubility:
- 500 g/L
- at the temperature of:
- 20 °C
