EC number: 259-515-6 | CAS number: 55184-72-0
Solubility in organic solvents / fat solubility
Administrative data
Link to relevant study record(s)
- Endpoint:
- solubility in organic solvents / fat solubility
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Justification for type of information:
- Testing for CAS 55184-72-0 is covered by tests with CAS 848588-96-5. Both substances are very similar since they differ mainly in the share of C13 (CAS 848588-96-5 C13> 80%; CAS 55184-72-0 > 95%). Hence, read across from CAS 848588-96-5 (source) to CAS 55184-72-0 (target) is considered as appropriate for both substances.
- Reason / purpose for cross-reference:
- read-across source
- Key result
- Medium:
- n-octanol
- Solubility:
- > 500 g/L
- Temp.:
- 20 °C
- Test substance stable:
- yes
- Executive summary:
In the non GLP Klimisch 1 key study from Frischmann (2013), the n-octanol solubility of Sodium bis(C11-14-isoalkyl, C13-rich) sulfosuccinate was determined according to OECD 105 with the exception that n-octanol instead of water was used.
The octanol solubility of Sodium bis(C11-14-isoalkyl, C13-rich) sulfosuccinate is greater than 500 g/L. Sodium bis(C11-14-isoalkyl, C13-rich) sulfosuccinate is miscible with octanol in any proportion. With increasing amount of test item a gel is formed.
Testing for CAS 55184-72-0 is covered by tests with CAS 848588-96-5. Both substances are very similar since they differ mainly in the share of C13 (CAS 848588-96-5 C13> 80%; CAS 55184-72-0 > 95%). Hence, read across from CAS 848588-96-5 (source) to CAS 55184-72-0 (target) is considered as appropriate for both substances.
The results of this study are considered relevant and reliable for the risk assessment.
Reference
The following aliquots of test item were added to 2 mL of n-octanol and stirred slowly for 10 minutes:
Aliquot |
Cumulative weighed sample (g) /Observation |
A |
0.02 clear solution |
B |
0.1 clear solution |
C |
0.5 clear solution |
D |
1.0 clear solution, increasing viscosity |
E |
2.0 jelly like, highly viscous |
While being added to the solvent, clear solutions with increasing viscosity were being formed, resulting in a gel after the addition of 2.0 g test item to 2 ml n-octanol.
