Water solubility
Administrative data
Link to relevant study record(s)
- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2013-11-04 to 2013-11-20
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study without detailed documentation
- Qualifier:
- according to guideline
- 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.
