- Executive summary:
In the non GLP Klimisch 1 key study from Frischmann (2012), the n-octanol solubility of Sulfosuccinic (ISOFA C10)DiE, Na was determined according to OECD 105 with the exception that n-octanol instead of water was used.
The octanol solubility of Sulfosuccinic (isoFA C10)diE, Na is greater than 500 g/L.Sulfosuccinic (isoFA C10)diE, Na is miscible with octanol 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
In a preliminary study different amounts of test item were mixed with 5 mL octanol. The obtained solution was clear until a gel was formed. With increasing amount of test item added, the solution became more gel like. When 10.1 of the test item were mixed with 5 mL octanol, a gel with a total weight of about 14.2 g was formed (10.1 g test item and 4.1 g n-Octanol). The final density of the gel is about 710 g/L. Due to the fact that the formation of the gel is a continuous process no discrete point can be identified at which the solution switches to gelling, the octanol solubility can be reported as > 500 g/L.
Description of key information
Solubility in n-octanol (20°C): > 500 g/L
Key value for chemical safety assessment
