Reference
Endpoint:
water solubility
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
test procedure in accordance with generally accepted scientific standards and described in sufficient detail
Justification for type of information:
Screening assessment to confirm very high water solublity
At this level of solubility, accurate assessment is not necessary
Qualifier:
according to guideline
Guideline:
OECD Guideline 105 (Water Solubility)
Version / remarks:
Screening study
GLP compliance:
no
Type of method:
flask method
Specific details on test material used for the study:
Batch no. SQU196
Appearance Prill
Composition Potassium benzoate > 99%
Key result
Water solubility:
ca. 492 g/L
Conc. based on:
test mat.
Loading of aqueous phase:
500 g/L
Incubation duration:
ca. 24 h
Temp.:
20 °C
pH:
ca. 9.2
Details on results:
Preliminary test, water solubility: 200-1000 g/l
Sample 1, 24 h: water solubility = 419.39 g/l, pH = 9.25
Sample 2, 48 h: water solubility = 493.85 g/l, pH = 9.22
Sample 3, 72 h: water solubility = 490.33 g/l, pH = 9.11
Values 2-3 are used for the calculation of the average of values.
Conclusions:
Very soluble in water.
