Guideline:
OECD Guideline 105 (Water Solubility)
GLP compliance:
no
Type of method:
flask method
Water solubility:
ca. 614 mg/L
Conc. based on:
act. ingr. (dissolved fraction)
Incubation duration:
24 h
Temp.:
20 °C
pH:
1.5
Water solubility:
ca. 670 mg/L
Conc. based on:
act. ingr. (dissolved fraction)
Incubation duration:
48 h
Temp.:
20 °C
pH:
1.5
Water solubility:
ca. 302 mg/L
Conc. based on:
act. ingr. (dissolved fraction)
Incubation duration:
72 h
Temp.:
20 °C
pH:
1.5
Water solubility:
ca. 292 mg/L
Conc. based on:
act. ingr. (dissolved fraction)
Incubation duration:
96 h
Temp.:
20 °C
pH:
1.5
Details on results:
After 48 h the determined values for water solubility decreased. The reason for this can be a thermal decomposition of OO-tert-butyl monoperoxymaleate at the test temperature (20 °C). No further information is available to determine the exact reason for the decrease of the observed effect.
Conclusions:
The determined final result for the water solubility of OO-tert-butyl monoperoxymaleate was calculated to be 642 mg/L at 20 °C (calculated as the average from timepoints 24 h and 48 h).
Executive summary:

The determined final result for the water solubility of OO-tert-butyl monoperoxymaleate was calculated to be 642 mg/L at 20 °C (calculated as the average from timepoints 24 h and 48 h). After 48 h the determined values for water solubility decreased. The reason for this can be a thermal decomposition of OO-tert-butyl monoperoxymaleate at the test temperature (20 °C). No further information is available to determine the exact reason for the decrease of the observed effect.

Description of key information

The determined final result for the water solubility of OO-tert-butyl monoperoxymaleate was calculated to be 642 mg/L at 20 °C (calculated as average from timepoints 24 h and 48 h).

Key value for chemical safety assessment

Water solubility:
642 mg/L
at the temperature of:
20 °C

Additional information

After 48 hours, the determined values for water solubility decreased. The reason for this could be a thermal decomposition of OO-tert-butyl monoperoxymaleate at the test temperature (20 °C). No further information is available to determine the exact reason for the decrease of the observed effect.
