Water solubility
Administrative data
Link to relevant study record(s)
- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Basic data given in peer reviewed journal (also assessed by OECD)
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Excess TPP was agitated in purified water for 48 h, allowed to stand in the dark for 1 week to permit phase seperation. The water phase was centrifuged and extracted with dichloromethane. Analysis was with GC/FID
- GLP compliance:
- not specified
- Type of method:
- flask method
- Specific details on test material used for the study:
- Commercial grade TPP
- Water solubility:
- 1.9 mg/L
- Temp.:
- 20 °C
- Remarks on result:
- other: pH not reported
- Details on results:
- Purified water used- exact pH not given
- Conclusions:
- Interpretation of results: slightly soluble (0.1-100 mg/L)
TPP can be considered as slighlty soluble in water - Executive summary:
- In a well documented study the water solubility of TPP has been determined as 1.9 mg/L
Reference
Purified water used- exact pH not given
Description of key information
The water solubility has been determined as 1.9 mg/L by Saeger et al.
Key value for chemical safety assessment
- Water solubility:
- 1.9 mg/L
- at the temperature of:
- 20 °C
Additional information
Various studies have been carried out to determine the water solubility of TPP. All studies indicate that TPP can be considered as slighly soluble in water. The three best documented studies give a water solubility of 1.9 - 2.1 mg/L at ambient temperatures.
