- Remarks on result:
- other: The water solubility of Sulfosuccinic (isoFA C10)diE, Na is greater than 170 g/L. Sulfosuccinic (isoFA C10)diE, Na is miscible with water in any proportion. With increasing amount of test item a gel is formed.
- Conclusions:
- Interpretation of results: very soluble (170 g/L)
- Executive summary:
In the non GLP Klimisch 1 key study from Frischmann (2012), the water solubility of Sulfosuccinic (ISOFA C10)DiE, Na was determined according to OECD 105 and EU method A.6.
The water solubility of Sulfosuccinic (isoFA C10)diE, Na is greater than 170 g/L. Sulfosuccinic (isoFA C10)diE, Na is miscible with water in any proportion. With increasing amount of test item a gel is formed.
The results of this study are considered relevant and reliable for the risk assessment.
Reference
With 2.1 g of test item being mixed with 10 g of water, a gel with a total weight of approximately 12.1 g has been formed. This is equivalent to 17.3 % (w/w) of test item in solution/gel.
As the density of the water will significantly increase with addition of the test item, it can be concluded that water solubility is about 170 g/L, resulting in a gel.
Due to the fact, that the formation of the gel is a continuous process and no discrete point can be identified at which dissolution in water switches to gelling, the water solubility can be approximated to > 170 g/L.
Thus the following results can be reported:
Water Solubility ( Sulfosuccinic (isoFA C10)diE, Na)> 170 g/L
The water solubility of Sulfosuccinic (isoFA C10)diE, Na is greater than 170 g/L. Sulfosuccinic (isoFA C10)diE, Na is miscible with water in any proportion. With increasing amount of test item a gel is formed.
The water solubility was determined at 20 °C. The pH value was 7.1
Description of key information
Water solubility (20°C): > 170 g/L
Key value for chemical safety assessment
- Water solubility:
- 170 g/L
- at the temperature of:
- 20 °C
