Endpoint:
water solubility
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2013
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Remarks:
Guideline compliant study with good documentation
Qualifier:
according to
Guideline:
OECD Guideline 105 (Water Solubility)
Qualifier:
according to
Guideline:
EU Method A.6 (Water Solubility)
GLP compliance:

Type of method:
flask method
Key result
Water solubility:
74.15 g/L
Temp.:
20 °C
pH:
>= 4.93 - <= 4.95

The concentrations of the different test solutions were calculated automatically using the equation of the calibration curve and considering the dilution factor 500 of the test solutions. The results are listed in the following table:

 

 

Nominal saturation concentration (g/L)

Water solubility, Results (g/L)

300

69.15

250

74.75

200

78.15

 

 

 

Total average concentration over three incubation times:

 

74.15 g/L, RSD 6.4 %

 

Thus, the following rounded value for Water solubility of the test item SODIUM DICYCLOHEXYL SULFOSUCCINATE can be reported when applying conditions described for water solubility according to EU test method L383 A/54-62 (EEC A.6):

 

 

Water solubility (SODIUM DICYCLOHEXYL SULFOSUCCINATE) = 74.15 g/L

 

The Water solubility was determined at 20 °C. The pH value of the aqueous solutions varied from 4.93 to 4.95.

Conclusions:
Interpretation of results (migrated information): soluble (1000-10000 mg/L)
Executive summary:

In the non GLP Klimisch 1 key study from Frischmann (2012), the water solubility Sodium Dicyclohexyl Sulfosuccinate was determined according to OECD 105 and EU method A.6. The water solubility was determined to be 74.15 g/L at 20°C.

The results of this study are considered relevant and reliable for the risk assessment.
