Reference
Endpoint:
water solubility
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2018
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
test procedure in accordance with national standard methods with acceptable restrictions
Reference:
Composition 0
Qualifier:
equivalent or similar to
Guideline:
EU Method A.6 (Water Solubility)
Version / remarks:
flask method
Deviations:
yes
Remarks:
two data points per sample instead of three; no substance specific analytical method.
Principles of method if other than guideline:
only two samples per concentration reported; no saturation point found; analytic determination with titration of acid is not substance specific
GLP compliance:
no
Type of method:
flask method
Test material information:
Composition 1
Key result
Water solubility:
> 80 vol%
Conc. based on:
test mat. (total fraction)
Loading of aqueous phase:
1 460 g/L
Incubation duration:
24 h
Temp.:
20 °C
pH:
< 0
Remarks on result:
completely miscible
Remarks:
clear solution obtained without any phase separation after 24h. Analytic tests from bottom and surface of sample show homogeneous solution
Details on results:
No obserrvation of phase separation at any of the nominal concentrations tested (20, 40, 60, 80 vol%).
